I rebuilt the Utah Teapot as a continous surface, with nice blends between the handle and spout and body. No, I don't know why I did this.

Milan (Italian: Milano) is a city in northern Italy, capital of Lombardy, and the second-most populous city in Italy after Rome, with the city proper having a population of 1,372,810 while its metropolitan city has a population of 3,245,308. Its continuously built-up urban area (that stretches beyond the boundaries of the Metropolitan City of Milan) has a population estimated to be about 5,270,000 over 1,891 square kilometres (730 square miles). The wider Milan metropolitan area, known as Greater Milan, is a polycentric metropolitan region that extends over central Lombardy and eastern Piedmont and which counts an estimated total population of 7.5 million, making it by far the largest metropolitan area in Italy and the 54th largest in the world. Milan served as capital of the Western Roman Empire from 286 to 402 and the Duchy of Milan during the medieval period and early modern age.
Milan is considered a leading alpha global city, with strengths in the field of the art, commerce, design, education, entertainment, fashion, finance, healthcare, media, services, research and tourism. Its business district hosts Italy's stock exchange and the headquarters of national and international banks and companies. In terms of GDP, it has the third-largest economy among European cities after Paris and London, but the fastest in growth among the three, and is the wealthiest among European non-capital cities. Milan is considered part of the Blue Banana and one of the "Four Motors for Europe".
The city has been recognized as one of the world's four fashion capitals thanks to several international events and fairs, including Milan Fashion Week and the Milan Furniture Fair, which are currently among the world's biggest in terms of revenue, visitors and growth. It hosted the Universal Exposition in 1906 and 2015. The city hosts numerous cultural institutions, academies and universities, with 11% of the national total enrolled students. Milan is the destination of 8 million overseas visitors every year, attracted by its museums and art galleries that boast some of the most important collections in the world, including major works by Leonardo da Vinci. The city is served by a large number of luxury hotels and is the fifth-most starred in the world by Michelin Guide. The city is home to two of Europe's most successful football teams, A.C. Milan and F.C. Internazionale, and one of Italy's main basketball teams, Olimpia Milano.

The Galleria Vittorio Emanuele II is Italy's oldest active shopping mall and a major landmark of Milan, Italy. Housed within a four-story double arcade in the center of town, the Galleria is named after Victor Emmanuel II, the first king of the Kingdom of Italy. It was designed in 1861 and built by architect Giuseppe Mengoni between 1865 and 1867.
Rochester is a town and historic city in the unitary authority of Medway in Kent, England. It is situated at the lowest bridging point of the River Medway about 30 miles (50 km) from London.
Rochester was for many years a favourite of Charles Dickens, who owned nearby Gads Hill Place, Higham,[1] basing many of his novels on the area. The Diocese of Rochester, the second oldest in England, is based at Rochester Cathedral and was responsible for the founding of a school, now The King's School in 604 AD,[2] which is recognised as being the second oldest continuously running school in the world. Rochester Castle, built by Bishop Gundulf of Rochester, has one of the best preserved keepsin either England or France, and during the First Barons' War (1215–1217) in King John's reign, baronial forces captured the castle from Archbishop Stephen Langton and held it against the king, who then besieged it.[3]
Neighbouring Chatham, Gillingham, Strood and a number of outlying villages, together with Rochester, nowadays make up the MedwayUnitary Authority area. It was, until 1998,[4]under the control of Kent County Council and is still part of the ceremonial county of Kent, under the latest Lieutenancies Act.[5]
Toponymy[edit]
The Romano-British name for Rochester was Durobrivae, later Durobrivis c. 730 and Dorobrevis in 844. The two commonly cited origins of this name are that it either came from "stronghold by the bridge(s)",[6] or is the latinisation of the British word Dourbruf meaning "swiftstream".[7]Durobrivis was pronounced 'Robrivis. Bede copied down this name, c. 730, mistaking its meaning as Hrofi's fortified camp (OE Hrofes cæster). From this we get c. 730 Hrofæscæstre, 811 Hrofescester, 1086 Rovescester, 1610 Rochester.[6] The Latinised adjective 'Roffensis' refers to Rochester.[7]
Neolithic remains have been found in the vicinity of Rochester; over time it has been variously occupied by Celts, Romans, Jutes and/or Saxons. During the Celtic period it was one of the two administrative centres of the Cantiaci tribe. During the Roman conquest of Britain a decisive battle was fought at the Medway somewhere near Rochester. The first bridge was subsequently constructed early in the Roman period. During the later Roman period the settlement was walled in stone. King Ethelbert of Kent(560–616) established a legal system which has been preserved in the 12th century Textus Roffensis. In AD 604 the bishopric and cathedral were founded. During this period, from the recall of the legions until the Norman conquest, Rochester was sacked at least twice and besieged on another occasion.
The medieval period saw the building of the current cathedral (1080–1130, 1227 and 1343), the building of two castles and the establishment of a significant town. Rochester Castle saw action in the sieges of 1215 and 1264. Its basic street plan was set out, constrained by the river, Watling Street, Rochester Priory and the castle.
Rochester has produced two martyrs: St John Fisher, executed by Henry VIII for refusing to sanction the divorce of Catherine of Aragon; and Bishop Nicholas Ridley, executed by Queen Mary for being an English Reformation protestant.
The city was raided by the Dutch as part of the Second Anglo-Dutch War. The Dutch, commanded by Admiral de Ruijter, broke through the chain at Upnor[8] and sailed to Rochester Bridge capturing part of the English fleet and burning it.[9]
The ancient City of Rochester merged with the Borough of Chatham and part of the Strood Rural District in 1974 to form the Borough of Medway. It was later renamed Rochester-upon-Medway, and its City status transferred to the entire borough. In 1998 another merger with the rest of the Medway Towns created the Medway Unitary Authority. The outgoing council neglected to appoint ceremonial "Charter Trustees" to continue to represent the historic Rochester area, causing Rochester to lose its City status – an error not even noticed by council officers for four years, until 2002.[10][11]
Military History
Rochester has for centuries been of great strategic importance through its position near the confluence of the Thames and the Medway. Rochester Castle was built to guard the river crossing, and the Royal Dockyard's establishment at Chatham witnessed the beginning of the Royal Navy's long period of supremacy. The town, as part of Medway, is surrounded by two circles of fortresses; the inner line built during the Napoleonic warsconsists of Fort Clarence, Fort Pitt, Fort Amherst and Fort Gillingham. The outer line of Palmerston Forts was built during the 1860s in light of the report by the Royal Commission on the Defence of the United Kingdomand consists of Fort Borstal, Fort Bridgewood, Fort Luton, and the Twydall Redoubts, with two additional forts on islands in the Medway, namely Fort Hoo and Fort Darnet.
During the First World War the Short Brothers' aircraft manufacturing company developed the first plane to launch a torpedo, the Short Admiralty Type 184, at its seaplane factory on the River Medway not far from Rochester Castle. In the intervening period between the 20th century World Wars the company established a world-wide reputation as a constructor of flying boats with aircraft such as the Singapore, Empire 'C'-Class and Sunderland. During the Second World War, Shorts also designed and manufactured the first four-engined bomber, the Stirling.
The UK's decline in naval power and shipbuilding competitiveness led to the government decommissioning the RN Shipyard at Chatham in 1984, which led to the subsequent demise of much local maritime industry. Rochester and its neighbouring communities were hit hard by this and have experienced a painful adjustment to a post-industrial economy, with much social deprivation and unemployment resulting. On the closure of Chatham Dockyard the area experienced an unprecedented surge in unemployment to 24%; this had dropped to 2.4% of the local population by 2014.[12]
Former City of Rochester[edit]
Rochester was recognised as a City from 1211 to 1998. The City of Rochester's ancient status was unique, as it had no formal council or Charter Trustees nor a Mayor, instead having the office of Admiral of the River Medway, whose incumbent acted as de facto civic leader.[13] On 1 April 1974, the City Council was abolished under the Local Government Act 1972, and the territory was merged with the District of Medway, Borough of Chatham and most of Strood Rural District to form a new a local government district called the Borough of Medway, within the county of Kent. Medway Borough Council applied to inherit Rochester's city status, but this was refused; instead letters patent were granted constituting the area of the former Rochester local government district to be the City of Rochester, to "perpetuate the ancient name" and to recall "the long history and proud heritage of the said City".[14] The Home Officesaid that the city status may be extended to the entire borough if it had "Rochester" in its name, so in 1979, Medway Borough Council renamed the borough to Borough of Rochester-upon-Medway, and in 1982, Rochester's city status was transferred to the entire borough by letters patent, with the district being called the City of Rochester-upon-Medway.[13]
On 1 April 1998, the existing local government districts of Rochester-upon-Medway and Gillingham were abolished and became the new unitary authority of Medway. The Department of Environment, Transport and the Regions informed the city council that since it was the local government district that officially held City status under the 1982 Letters Patent, the council would need to appoint charter trustees to preserve its city status, but the outgoing Labour-run council decided not to appoint charter trustees, so the city status was lost when Rochester-upon-Medway was abolished as a local government district.[15][16][17] The other local government districts with City status that were abolished around this time, Bath and Hereford, decided to appoint Charter Trustees to maintain the existence of their own cities and the mayoralties. The incoming Medway Council apparently only became aware of this when, in 2002, it was advised that Rochester was not on the Lord Chancellor's Office's list of cities.[18][19]
In 2010, Medway Council started to refer to the "City of Medway" in promotional material, but it was rebuked and instructed not to do so in future by the Advertising Standards Authority.[20]
Governance[edit]
Civic history and traditions[edit]
Rochester and its neighbours, Chatham and Gillingham, form a single large urban area known as the Medway Towns with a population of about 250,000. Since Norman times Rochester had always governed land on the other side of the Medway in Strood, which was known as Strood Intra; before 1835 it was about 100 yards (91 m) wide and stretched to Gun Lane. In the 1835 Municipal Corporations Act the boundaries were extended to include more of Strood and Frindsbury, and part of Chatham known as Chatham Intra. In 1974, Rochester City Council was abolished and superseded by Medway Borough Council, which also included the parishes of Cuxton, Halling and Cliffe, and the Hoo Peninsula. In 1979 the borough became Rochester-upon-Medway. The Admiral of the River Medway was ex-officio Mayor of Rochester and this dignity transferred to the Mayor of Medway when that unitary authority was created, along with the Admiralty Court for the River which constitutes a committee of the Council.[21]
Like many of the mediaeval towns of England, Rochester had civic Freemen whose historic duties and rights were abolished by the Municipal Corporations Act 1835. However, the Guild of Free Fishers and Dredgers continues to the present day and retains rights, duties and responsibilities on the Medway, between Sheerness and Hawkwood Stone.[22] This ancient corporate body convenes at the Admiralty Court whose Jury of Freemen is responsible for the conservancy of the River as enshrined in current legislation. The City Freedom can be obtained by residents after serving a period of "servitude", i.e. apprenticeship (traditionally seven years), before admission as a Freeman. The annual ceremonial Beating of the Boundsby the River Medway takes place after the Admiralty Court, usually on the first Saturday of July.
Rochester first obtained City status in 1211, but this was lost due to an administrative oversight when Rochester was absorbed by the Medway Unitary Authority.[10] Subsequently, the Medway Unitary Authority has applied for City status for Medway as a whole, rather than merely for Rochester. Medway applied unsuccessfully for City status in 2000 and 2002 and again in the Queen's Diamond Jubilee Year of 2012.[23] Any future bid to regain formal City status has been recommended to be made under the aegis of Rochester-upon-Medway.
Ecclesiastical parishes[edit]
There were three medieval parishes: St Nicholas', St Margaret's and St Clement's. St Clement's was in Horsewash Lane until the last vicar died in 1538 when it was joined with St Nicholas' parish; the church last remaining foundations were finally removed when the railway was being constructed in the 1850s. St Nicholas' Church was built in 1421 beside the cathedral to serve as a parish church for the citizens of Rochester. The ancient cathedral included the Benedictine monastic priory of St Andrew with greater status than the local parishes.[24] Rochester's pre-1537 diocese, under the jurisdiction of the Church of Rome, covered a vast area extending into East Anglia and included all of Essex.[25]
As a result of the restructuring of the Church during the Reformation the cathedral was reconsecrated as the Cathedral Church of Christ and the Blessed Virgin Mary without parochial responsibilities, being a diocesan church.[26] In the 19th century the parish of St Peter's was created to serve the burgeoning city with the new church being consecrated in 1859. Following demographic shifts, St Peter's and St Margaret's were recombined as a joint benefice in 1953 with the parish of St Nicholas with St Clement being absorbed in 1971.[27] The combined parish is now the "Parish of St Peter with St Margaret", centred at the new (1973) Parish Centre in The Delce (St Peter's) with St Margaret's remaining as a chapel-of-ease. Old St Peter's was demolished in 1974, while St Nicholas' Church has been converted into the diocesan offices but remains consecrated. Continued expansion south has led to the creation of an additional more recent parish of St Justus (1956) covering The Tideway estate and surrounding area.[28]
A church dedicated to St Mary the Virgin at Eastgate, which was of Anglo-Saxon foundation, is understood to have constituted a parish until the Middle Ages, but few records survive.[29]
Geography
Rochester lies within the area, known to geologists, as the London Basin. The low-lying Hoo peninsula to the north of the town consists of London Clay, and the alluvium brought down by the two rivers—the Thames and the Medway—whose confluence is in this area. The land rises from the river, and being on the dip slope of the North Downs, this consists of chalksurmounted by the Blackheath Beds of sand and gravel.
As a human settlement, Rochester became established as the lowest river crossing of the River Medway, well before the arrival of the Romans.
It is a focal point between two routes, being part of the main route connecting London with the Continent and the north-south routes following the course of the Medway connecting Maidstone and the Weald of Kent with the Thames and the North Sea. The Thames Marshes were an important source of salt. Rochester's roads follow north Kent's valleys and ridges of steep-sided chalk bournes. There are four ways out of town to the south: up Star Hill, via The Delce,[30] along the Maidstone Road or through Borstal. The town is inextricably linked with the neighbouring Medway Towns but separate from Maidstone by a protective ridge known as the Downs, a designated area of Outstanding Natural Beauty.
At its most limited geographical size, Rochester is defined as the market town within the city walls, now associated with the historic medieval city. However, Rochester historically also included the ancient wards of Strood Intra on the river's west bank, and Chatham Intra as well as the three old parishes on the Medway's east bank.
The diocese of Rochester is another geographical entity which can be referred to as Rochester.
Climate[edit]
Rochester has an oceanic climate similar to much of southern England, being accorded Köppen Climate Classification-subtype of "Cfb" (Marine West Coast Climate).[31]
On 10 August 2003, neighbouring Gravesend recorded one of the highest temperatures since meteorogical records began in the United Kingdom, with a reading of 38.1 degrees Celsius (100.6 degrees Fahrenheit),[32]only beaten by Brogdale, near Faversham, 22 miles (35 km) to the ESE.[33] The weather station at Brogdale is run by a volunteer, only reporting its data once a month, whereas Gravesend, which has an official Met Office site at the PLA pilot station,[34] reports data hourly.
Being near the mouth of the Thames Estuary with the North Sea, Rochester is relatively close to continental Europe and enjoys a somewhat less temperate climate than other parts of Kent and most of East Anglia. It is therefore less cloudy, drier and less prone to Atlanticdepressions with their associated wind and rain than western regions of Britain, as well as being hotter in summer and colder in winter. Rochester city centre's micro-climate is more accurately reflected by these officially recorded figures than by readings taken at Rochester Airport.[35]
North and North West Kent continue to record higher temperatures in summer, sometimes being the hottest area of the country, eg. on the warmest day of 2011, when temperatures reached 33.1 degrees.[36]Additionally, it holds at least two records for the year 2010, of 30.9 degrees[37] and 31.7 degrees C.[38] Another record was set during England's Indian summer of 2011 with 29.9 degrees C., the highest temperature ever recorded in the UK for October.

Building
Rochester comprises numerous important historic buildings, the most prominent of which are the Guildhall, the Corn Exchange, Restoration House, Eastgate House, as well as Rochester Castle and Rochester Cathedral. Many of the town centre's old buildings date from as early as the 14th century up to the 18th century. The chapel of St Bartholomew's Hospital dates from the ancient priory hospital's foundation in 1078.
Economy
Thomas Aveling started a small business in 1850 producing and repairing agricultural plant equipment. In 1861 this became the firm of Aveling and Porter, which was to become the largest manufacturer of agricultural machinery and steam rollers in the country.[39] Aveling was elected Admiral of the River Medway (i.e. Mayor of Rochester) for 1869-70.
Culture[edit]
Sweeps Festival[edit]
Since 1980 the city has seen the revival of the historic Rochester Jack-in-the-Green May Day dancing chimney sweeps tradition, which had died out in the early 1900s. Though not unique to Rochester (similar sweeps' gatherings were held across southern England, notably in Bristol, Deptford, Whitstable and Hastings), its revival was directly inspired by Dickens' description of the celebration in Sketches by Boz.
The festival has since grown from a small gathering of local Morris dancesides to one of the largest in the world.[40] The festival begins with the "Awakening of Jack-in-the-Green" ceremony,[41] and continues in Rochester High Street over the May Bank Holiday weekend.
There are numerous other festivals in Rochester apart from the Sweeps Festival. The association with Dickens is the theme for Rochester's two Dickens Festivals held annually in June and December.[42] The Medway Fuse Festival[43] usually arranges performances in Rochester and the latest festival to take shape is the Rochester Literature Festival, the brainchild of three local writers.[44]
Library[edit]
A new public library was built alongside the Adult Education Centre, Eastgate. This enabled the registry office to move from Maidstone Road, Chatham into the Corn Exchange on Rochester High Street (where the library was formerly housed). As mentioned in a report presented to Medway Council's Community Services Overview and Scrutiny Committee on 28 March 2006, the new library opened in late summer (2006).[45]
Theatre[edit]
There is a small amateur theatre called Medway Little Theatre on St Margaret's Banks next to Rochester High Street near the railway station.[46] The theatre was formed out of a creative alliance with the Medway Theatre Club, managed by Marion Martin, at St Luke's Methodist Church on City Way, Rochester[47] between 1985 and 1988, since when drama and theatre studies have become well established in Rochester owing to the dedication of the Medway Theatre Club.[48]
Media[edit]
Local newspapers for Rochester include the Medway Messenger, published by the KM Group, and free newspapers such as Medway Extra(KM Group) and Yourmedway (KOS Media).
The local commercial radio station for Rochester is KMFM Medway, owned by the KM Group. Medway is also served by community radio station Radio Sunlight. The area also receives broadcasts from county-wide stations BBC Radio Kent, Heart and Gold, as well as from various Essex and Greater London radio stations.[49]
Sport[edit]
Football is played with many teams competing in Saturday and Sunday leagues.[50] The local football club is Rochester United F.C. Rochester F.C. was its old football club but has been defunct for many decades. Rugby is also played; Medway R.F.C. play their matches at Priestfields and Old Williamsonians is associated with Sir Joseph Williamson's Mathematical School.[51]
Cricket is played in the town, with teams entered in the Kent Cricket League. Holcombe Hockey Club is one of the largest in the country,[52]and is based at Holcombe Park. The men's and women's 1st XI are part of the England Hockey League.[53] Speedway was staged on a track adjacent to City Way that opened in 1932. Proposals for a revival in the early 1970s did not materialise and the Rochester Bombers became the Romford Bombers.[54]
Sailing and rowing are also popular on the River Medway with respective clubs being based in Rochester.[55][56]
Film[edit]
The 1959 James Bond Goldfinger describes Bond driving along the A2through the Medway Towns from Strood to Chatham. Of interest is the mention of "inevitable traffic jams" on the Strood side of Rochester Bridge, the novel being written some years prior to the construction of the M2 motorway Medway bypass.
Rochester is the setting of the controversial 1965 Peter Watkins television film The War Game, which depicts the town's destruction by a nuclear missile.[57] The opening sequence was shot in Chatham Town Hall, but the credits particularly thank the people of Dover, Gravesend and Tonbridge.
The 2011 adventure film Ironclad (dir. Jonathan English) is based upon the 1215 siege of Rochester Castle. There are however a few areaswhere the plot differs from accepted historical narrative.
Notable people[edit]
Charles Dickens
The historic city was for many years the favourite of Charles Dickens, who lived within the diocese at nearby Gads Hill Place, Higham, many of his novels being based on the area. Descriptions of the town appear in Pickwick Papers, Great Expectations and (lightly fictionalised as "Cloisterham") in The Mystery of Edwin Drood. Elements of two houses in Rochester, Satis House and Restoration House, are used for Miss Havisham's house in Great Expectations, Satis House.[58]
Sybil Thorndike
The actress Dame Sybil Thorndike and her brother Russell were brought up in Minor Canon Row adjacent to the cathedral; the daughter of a canon of Rochester Cathedral, she was educated at Rochester Grammar School for Girls. A local doctors' practice,[59] local dental practice[60] and a hall at Rochester Grammar School are all named after her.[61]
Peter Buck
Sir Peter Buck was Admiral of the Medway in the 17th century; knightedin 1603 he and Bishop Barlow hosted King James, the Stuart royal familyand the King of Denmark in 1606. A civil servant to The Royal Dockyardand Lord High Admiral, Buck lived at Eastgate House, Rochester.
Denis Redman
Major-General Denis Redman, a World War II veteran, was born and raised in Rochester and later became a founder member of REME, head of his Corps and a Major-General in the British Army.

Here are detailed photos of my Saks Cinderella doll. She is #1990 of 2500. I purchased her during the Cyber Monday sale (on November 26), so got her for $100 less than the list price. I received her today (Saturday December 1) from FedEx. She was double boxed, and the box and doll are in nearly perfect shape. There was a small mark on her nose that I rubbed off, and some stray hairs in her eyes that I removed with tweeters. Her bangs are very neat, as are her eyelashes. Her updo is in pretty good shape, but I'll see if I can make it neater when I debox her. Her dress is slightly bluish silver and is very voluminous. I love the iridescence of the gems in her dress. She looks so elegant and beautiful, and would definitely turn heads in a Royal Ball. She makes the 2012 Disney Store Cinderella LE doll look frumpy and cheap. She is still available from the Saks website.

Our beloved Peter Broderick invited Lubomyr to come to Berlin and teach him about his very special field "continuous music". Peter is in return showing him around Berlin to play & record with his friends. Today they did a session in Nils Frahm's studio. Lubomyr played a solo composition, Peter joined him for a complete new one, and Nils, Peter & Lubomyr ended the whole thing with a beautiful jam. What a treat!
Mural "Continuous City", Lodz, Poland
Author Sebastian Bozek. The point of reference was the city understood as a continuous, fluid structure, changing form, neither open nor closed, without beginning or end. The architectural structure of Łódź, which is currently undergoing an intensive process of transformation, was also an inspiration.
Samarkand is a city in southeastern Uzbekistan and among the oldest continuously inhabited cities in Central Asia. Samarkand is the capital of the Samarkand Region and a district-level city, that includes the urban-type settlements Kimyogarlar, Farhod and Khishrav. With 551,700 inhabitants (2021)] it is the third-largest city in Uzbekistan.
There is evidence of human activity in the area of the city dating from the late Paleolithic Era. Though there is no direct evidence of when Samarkand was founded, several theories propose that it was founded between the 8th and 7th centuries BC. Prospering from its location on the Silk Road between China, Persia and Europe, at times Samarkand was one of the largest cities in Central Asia, and was an important city of the empires of Greater Iran. By the time of the Persian Achaemenid Empire, it was the capital of the Sogdian satrapy. The city was conquered by Alexander the Great in 329 BC, when it was known as Markanda, which was rendered in Greek as Μαράκανδα. The city was ruled by a succession of Iranian and Turkic rulers until it was conquered by the Mongols under Genghis Khan in 1220.
The city is noted as a centre of Islamic scholarly study and the birthplace of the Timurid Renaissance. In the 14th century, Timur made it the capital of his empire and the site of his mausoleum, the Gur-e Amir. The Bibi-Khanym Mosque, rebuilt during the Soviet era, remains one of the city's most notable landmarks. Samarkand's Registan square was the city's ancient centre and is bounded by three monumental religious buildings. The city has carefully preserved the traditions of ancient crafts: embroidery, goldwork, silk weaving, copper engraving, ceramics, wood carving, and wood painting. In 2001, UNESCO added the city to its World Heritage List as Samarkand – Crossroads of Cultures.
Modern Samarkand is divided into two parts: the old city, which includes historical monuments, shops, and old private houses; and the new city, which was developed during the days of the Russian Empire and Soviet Union and includes administrative buildings along with cultural centres and educational institutions. On 15 and 16 September 2022, the city hosted the 2022 SCO summit.
Samarkand has a multicultural and plurilingual history that was significantly modified by the process of national delimitation in Central Asia. Many inhabitants of the city are native or bilingual speakers of the Tajik language, whereas Uzbek is the official language and Russian is also widely used in the public sphere, as per Uzbekistan's language policy.

After that event was over, there was more rain and the Tram/Train system was shut down for a week due to more flooding on November 30th, blocking the line through Rotherham for the container traffic; so it wasn't having a very auspicious start to proceedings. In addition, the ground at Tinsley, unused to the continuous heavy road traffic, had in places subsided, near and underneath the old Wood Lane road bridge causing a problem getting the heavy traffic in and out. The site looked a mess before all the rain but at least it was operating well, see-
www.flickr.com/photos/daohaiku/48990004171/
with 4 inbound and 4 outbound workings per 24 hours, after the heavy rain, it all looked ghastly. Now, with Newell & Wright having quit the site after the last move went out on December 9th, it actually looks worse than it did before they arrived with the small forest of silver birch having been cleared to make way for the container storage in the distance, towards the Sheffield Parkway. At top left, the line of wagons won the left, which had been shunted out of the way to permit the reversal process from the remaining section of the Yard to the right of the two large M&S buildings at lower left, are still there and I guess they may well be left as such for a while. All the infrastructure installed by N&W has been removed, the large concrete blocks show the edge of the inbound HGV road and their left, the section which collapsed and has had material piled in to solve the subsidence issue, it now has flooded trenches along it from the HGV tyre tracks. This was never meant to be used for this type of operation and though the Yard did flood occasionally in heavy rain, it was at the other side of the bridge near the control tower; the lie of the land here clearly looks as if it was never meant for this sort of operation; not without a deal of money spending on it to provide the necessary structural support? The flat storage space beyond looks little better and if there had been more rain, it looks like this all could have got a whole lot worse. It may well prove to be a stark reminder to anyone else wishing to use the place, that this is what they may well be faced with in times of adverse weather... it is after all, a hole in the ground!
At upper right, a 'Satsuma liveried' HGV passes east along the Sheffield Parkway underneath, a buffer stop has been installed at the end of the revitalised section of line and a new palisade fence has been put up to protect the terminal from thieves. The trackwork in the foreground on the left looks a little 'make-do-and-mend' and reflects, possibly, the temporary nature which this was deemed to be, though that is not what I was informed, from one of the local personell who stated it was to be a permanent installation as the terminal at Masbrough had now run out of space and resources to deal with the volume of traffic.
At lower left, in thankfully great lighting conditions which was prevalent for all the shots, the view looks north-west to the line coming in from the sidings, the last bit of the old Tinsley Yard, at the right-hand side of the large M&S buildings and from where the GBRf locomotives used to reverse their container traffic right along to the other end of the single line, see-

The dramatic skies say it all, what a disappointment after to being so enthusiastic about a new lease of life for the place... and just the sort of operation which could have done well there... so, no new line to Treeton for the traffic, no container flows through Kilnhurst and Rotherham Central, no more interest in operations along from Wood Lane on both sides...

Description from Corning Museum of Glass:
Continuous Mile took Liza Lou longer than a year to make with a team of more than 50 beadworkers from several townships in KwaZulu-Natal, South Africa. The monumental sculpture is composed of a coiled and stacked cotton rope, measuring a mile in length, sewn with more than 4.5 million glossy black glass beads. It is a work about work, about process, about finding meaning in the everyday, and about managing many hands to create something that could not be made by one person alone. Continuous Mile was produced in an edition of two in black, and an edition of two in white. Based in Los Angeles, Liza Lou emerged as a presence in the art world in 1996 with an exhibition at the New Museum of Contemporary Art, New York, of Kitchen, a sculptural tableau utilizing millions of beads, which took five years for her, working alone, to make. Architectural in scale, Kitchen introduced some of Lou’s recurring themes: labor, confinement, and human endurance. Her meticulous placement of individual beads and the scale of the project represent a heroic effort that honors centuries of uncelebrated women’s work. In 2002, Lou received a John D. and Catherine T. MacArthur Foundation Fellowship. With the goal of developing an economically sustainable project, she moved her studio in 2005 to Durban, South Africa, where she assembled a team of Zulu women, all skilled beadworkers, to enable her to continue creating her labor-intensive art works. She has explored diverse subjects throughout her career, beading a prison cell, a closet, representations of deities, portraits of the American presidents, a trailer, prayer rugs, images of Adam and Eve, a security fence rimmed in razor wire, a toilet, and a noose, all in life-size scale. Unsigned. Published: Eleanor Heartney and others, Liza Lou, New York: Skira/Rizzoli, 2011, pp. 218–221. The artist’s collaboration with South African beadworkers is described in her catalog Durban Diaries, London: White Cube, 2012.
The International Space Station (ISS) is a space station (habitable artificial satellite) in low Earth orbit. The ISS programme is a joint project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).[6][7] The ownership and use of the space station is established by intergovernmental treaties and agreements.[8]
The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields.[9][10][11] The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.[12] The ISS maintains an orbit with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft.[13] It circles the Earth in roughly 92 minutes and completes 15.5 orbits per day.[14]
The station is divided into two sections, the Russian Orbital Segment (ROS), which is operated by Russia, and the United States Orbital Segment (USOS), which is shared by many nations. Roscosmos has endorsed the continued operation of ISS through 2024,[15] but had previously proposed using elements of the Russian segment to construct a new Russian space station called OPSEK.[16]As of December 2018, the station is expected to operate until 2030.[17]
The first ISS component was launched in 1998, with the first long-term residents arriving on 2 November 2000.[18] Since then, the station has been continuously occupied for 18 years and 359 days.[19] This is the longest continuous human presence in low Earth orbit, having surpassed the previous record of 9 years and 357 days held by Mir. The latest major pressurised module was fitted in 2011, with an experimental inflatable space habitat added in 2016. Development and assembly of the station continues, with several major new Russian elements scheduled for launch starting in 2020. The ISS is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth.[20][21] The ISS consists of pressurised habitation modules, structural trusses, solar arrays, radiators, docking ports, experiment bays and robotic arms. Major ISS modules have been launched by Russian Proton and Soyuz rockets and US Space Shuttles.[22]
The ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations as well as Skylab from the US. The station is serviced by a variety of visiting spacecraft: the Russian Soyuz and Progress, the US Dragon and Cygnus, the Japanese H-II Transfer Vehicle,[6] and the European Automated Transfer Vehicle. The Dragon spacecraft allows the return of pressurised cargo to Earth (downmass), which is used for example to repatriate scientific experiments for further analysis. The Soyuz return capsule has minimal downmass capability next to the astronauts.
The ISS has been visited by astronauts, cosmonauts and space tourists from 18 different nations. As of 14 March 2019, 236 people from 18 countries had visited the space station, many of them multiple times. The United States sent 149 people, Russia sent 47, nine were Japanese, eight were Canadian, five were Italian, four were French, three were German, and there were one each from Belgium, Brazil, Denmark, Kazakhstan, Malaysia, the Netherlands, South Africa, United Arab Emirates, South Korea, Spain, Sweden, and the United Kingdom.[23]

Purpose
The ISS was originally intended to be a laboratory, observatory, and factory while providing transportation, maintenance, and a low Earth orbit staging base for possible future missions to the Moon, Mars, and asteroids. However, not all of the uses envisioned in the initial Memorandum of Understanding between NASA and Roskosmos have come to fruition.[24] In the 2010 United States National Space Policy, the ISS was given additional roles of serving commercial, diplomatic[25] and educational purposes.[26]
Scientific research

The ISS provides a platform to conduct scientific research, with power, data, cooling, and crew available to support experiments. Small uncrewed spacecraft can also provide platforms for experiments, especially those involving zero gravity and exposure to space, but space stations offer a long-term environment where studies can be performed potentially for decades, combined with ready access by human researchers.[27][28]
The ISS simplifies individual experiments by allowing groups of experiments to share the same launches and crew time. Research is conducted in a wide variety of fields, including astrobiology, astronomy, physical sciences, materials science, space weather, meteorology, and human research including space medicine and the life sciences.[9][10][11][29][30] Scientists on Earth have timely access to the data and can suggest experimental modifications to the crew. If follow-on experiments are necessary, the routinely scheduled launches of resupply craft allows new hardware to be launched with relative ease.[28] Crews fly expeditions of several months' duration, providing approximately 160 person-hours per week of labour with a crew of 6. However, a considerable amount of crew time is taken up by station maintenance.[9][31]
Perhaps the most notable ISS experiment is the Alpha Magnetic Spectrometer (AMS), which is intended to detect dark matter and answer other fundamental questions about our universe and is as important as the Hubble Space Telescope according to NASA. Currently docked on station, it could not have been easily accommodated on a free flying satellite platform because of its power and bandwidth needs.[32][33] On 3 April 2013, scientists reported that hints of dark matter may have been detected by the AMS.[34][35][36][37][38][39] According to the scientists, "The first results from the space-borne Alpha Magnetic Spectrometer confirm an unexplained excess of high-energy positrons in Earth-bound cosmic rays."
The space environment is hostile to life. Unprotected presence in space is characterised by an intense radiation field (consisting primarily of protons and other subatomic charged particles from the solar wind, in addition to cosmic rays), high vacuum, extreme temperatures, and microgravity.[40] Some simple forms of life called extremophiles,[41] as well as small invertebrates called tardigrades[42] can survive in this environment in an extremely dry state through desiccation.
Medical research improves knowledge about the effects of long-term space exposure on the human body, including muscle atrophy, bone loss, and fluid shift. This data will be used to determine whether high duration human spaceflight and space colonisation are feasible. As of 2006, data on bone loss and muscular atrophy suggest that there would be a significant risk of fractures and movement problems if astronauts landed on a planet after a lengthy interplanetary cruise, such as the six-month interval required to travel to Mars.[43][44]
Medical studies are conducted aboard the ISS on behalf of the National Space Biomedical Research Institute (NSBRI). Prominent among these is the Advanced Diagnostic Ultrasound in Microgravity study in which astronauts perform ultrasound scans under the guidance of remote experts. The study considers the diagnosis and treatment of medical conditions in space. Usually, there is no physician on board the ISS and diagnosis of medical conditions is a challenge. It is anticipated that remotely guided ultrasound scans will have application on Earth in emergency and rural care situations where access to a trained physician is difficult.[45][46][47]
Free fall

Gravity at the altitude of the ISS is approximately 90% as strong as at Earth's surface, but objects in orbit are in a continuous state of freefall, resulting in an apparent state of weightlessness.[48] This perceived weightlessness is disturbed by five separate effects:[49]
Drag from the residual atmosphere.
Vibration from the movements of mechanical systems and the crew.
Actuation of the on-board attitude control moment gyroscopes.
Thruster firings for attitude or orbital changes.
Gravity-gradient effects, also known as tidal effects. Items at different locations within the ISS would, if not attached to the station, follow slightly different orbits. Being mechanically interconnected these items experience small forces that keep the station moving as a rigid body.
Researchers are investigating the effect of the station's near-weightless environment on the evolution, development, growth and internal processes of plants and animals. In response to some of this data, NASA wants to investigate microgravity's effects on the growth of three-dimensional, human-like tissues, and the unusual protein crystals that can be formed in space.[10]
Investigating the physics of fluids in microgravity will provide better models of the behaviour of fluids. Because fluids can be almost completely combined in microgravity, physicists investigate fluids that do not mix well on Earth. In addition, examining reactions that are slowed by low gravity and low temperatures will improve our understanding of superconductivity.[10]
The study of materials science is an important ISS research activity, with the objective of reaping economic benefits through the improvement of techniques used on the ground.[50] Other areas of interest include the effect of the low gravity environment on combustion, through the study of the efficiency of burning and control of emissions and pollutants. These findings may improve current knowledge about energy production, and lead to economic and environmental benefits. Future plans are for the researchers aboard the ISS to examine aerosols, ozone, water vapour, and oxides in Earth's atmosphere, as well as cosmic rays, cosmic dust, antimatter, and dark matter in the universe.[10]
Exploration
A 3D plan of the Russia-based MARS-500 complex, used for ground-based experiments which complement ISS-based preparations for a human mission to Mars
The ISS provides a location in the relative safety of Low Earth Orbit to test spacecraft systems that will be required for long-duration missions to the Moon and Mars. This provides experience in operations, maintenance as well as repair and replacement activities on-orbit, which will be essential skills in operating spacecraft farther from Earth, mission risks can be reduced and the capabilities of interplanetary spacecraft advanced.[12] Referring to the MARS-500 experiment, ESA states that "Whereas the ISS is essential for answering questions concerning the possible impact of weightlessness, radiation and other space-specific factors, aspects such as the effect of long-term isolation and confinement can be more appropriately addressed via ground-based simulations".[51] Sergey Krasnov, the head of human space flight programmes for Russia's space agency, Roscosmos, in 2011 suggested a "shorter version" of MARS-500 may be carried out on the ISS.[52]
In 2009, noting the value of the partnership framework itself, Sergey Krasnov wrote, "When compared with partners acting separately, partners developing complementary abilities and resources could give us much more assurance of the success and safety of space exploration. The ISS is helping further advance near-Earth space exploration and realisation of prospective programmes of research and exploration of the Solar system, including the Moon and Mars."[53] A crewed mission to Mars may be a multinational effort involving space agencies and countries outside the current ISS partnership. In 2010, ESA Director-General Jean-Jacques Dordain stated his agency was ready to propose to the other four partners that China, India and South Korea be invited to join the ISS partnership.[54] NASA chief Charlie Bolden stated in February 2011, "Any mission to Mars is likely to be a global effort".[55] Currently, US federal legislation prevents NASA co-operation with China on space projects.[56]
Education and cultural outreach

The ISS crew provides opportunities for students on Earth by running student-developed experiments, making educational demonstrations, allowing for student participation in classroom versions of ISS experiments, and directly engaging students using radio, videolink and email.[6][57] ESA offers a wide range of free teaching materials that can be downloaded for use in classrooms.[58] In one lesson, students can navigate a 3-D model of the interior and exterior of the ISS, and face spontaneous challenges to solve in real time.[59]
JAXA aims to inspire children to "pursue craftsmanship" and to heighten their "awareness of the importance of life and their responsibilities in society."[60] Through a series of education guides, a deeper understanding of the past and near-term future of crewed space flight, as well as that of Earth and life, will be learned.[61][62] In the JAXA Seeds in Space experiments, the mutation effects of spaceflight on plant seeds aboard the ISS is explored. Students grow sunflower seeds which flew on the ISS for about nine months. In the first phase of Kibō utilisation from 2008 to mid-2010, researchers from more than a dozen Japanese universities conducted experiments in diverse fields.[63]

Cultural activities are another major objective. Tetsuo Tanaka, director of JAXA's Space Environment and Utilization Center, says "There is something about space that touches even people who are not interested in science."[64]
Amateur Radio on the ISS (ARISS) is a volunteer programme which encourages students worldwide to pursue careers in science, technology, engineering and mathematics through amateur radio communications opportunities with the ISS crew. ARISS is an international working group, consisting of delegations from nine countries including several countries in Europe as well as Japan, Russia, Canada, and the United States. In areas where radio equipment cannot be used, speakerphones connect students to ground stations which then connect the calls to the station.[65]
First Orbit is a feature-length documentary film about Vostok 1, the first crewed space flight around the Earth. By matching the orbit of the International Space Station to that of Vostok 1 as closely as possible, in terms of ground path and time of day, documentary filmmaker Christopher Riley and ESA astronaut Paolo Nespoli were able to film the view that Yuri Gagarin saw on his pioneering orbital space flight. This new footage was cut together with the original Vostok 1 mission audio recordings sourced from the Russian State Archive. Nespoli, during Expedition 26/27, filmed the majority of the footage for this documentary film, and as a result is credited as its director of photography.[66] The film was streamed through the website firstorbit.org in a global YouTube premiere in 2011, under a free licence.[67]
In May 2013, commander Chris Hadfield shot a music video of David Bowie's "Space Oddity" on board the station; the film was released on YouTube.[68] It was the first music video ever to be filmed in space.[69]
In November 2017, while participating in Expedition 52/53 on the ISS, Paolo Nespoli made two recordings (one in English the other in his native Italian) of his spoken voice, for use on Wikipedia articles. These were the first content made specifically for Wikipedia, in space.[70][71]
Manufacturing
Main article: Manufacturing of the International Space Station
ISS module Node 2 manufacturing and processing in the SSPF
Since the International Space Station is a multi-national collaborative project, the components for in-orbit assembly were manufactured in various countries around the world. Beginning in the mid 1990s, the U.S. components Destiny, Unity, the Integrated Truss Structure, and the solar arrays were fabricated at the Marshall Space Flight Center and the Michoud Assembly Facility. These modules were delivered to the Operations and Checkout Building and the Space Station Processing Facility for final assembly and processing for launch.[72]
The Russian modules, including Zarya and Zvezda, were manufactured at the Khrunichev State Research and Production Space Center in Moscow. Zvezda was initially manufactured in 1985 as a component for Mir-2, but was never launched and instead became the ISS Service Module.[73]
The European Space Agency Columbus module was manufactured at the European Space Research and Technology Centre (ESTEC) in the Netherlands, along with many other contractors throughout Europe.[74] The other ESA-built modules - Harmony, Tranquility, the Leonardo MPLM, and the Cupola - were initially manufactured at the Thales Alenia Space factory located at the Cannes Mandelieu Space Center. The structural steel hulls of the modules were transported by aircraft to the Kennedy Space Center SSPF for launch processing.[75]
The Japanese Experiment Module Kibō, was fabricated in various technology manufacturing facilities in Japan, at the NASDA (now JAXA) Tanegashima Space Center, and the Institute of Space and Astronautical Science. The Kibo module was transported by ship and flown by aircraft to the KSC Space Station Processing Facility.[76]
The Mobile Servicing System, consisting of the Canadarm2 and the Dextre grapple fixture, was manufactured at various factories in Canada and the United States under contract by the Canadian Space Agency. The mobile base system, a connecting framework for Canadarm2 mounted on rails, was built by Northrop Grumman.
Assembly
Main articles: Assembly of the International Space Station and List of ISS spacewalks
The assembly of the International Space Station, a major endeavour in space architecture, began in November 1998.[3] Russian modules launched and docked robotically, with the exception of Rassvet. All other modules were delivered by the Space Shuttle, which required installation by ISS and shuttle crewmembers using the Canadarm2 (SSRMS) and extra-vehicular activities (EVAs); as of 5 June 2011, they had added 159 components during more than 1,000 hours of EVA (see List of ISS spacewalks). 127 of these spacewalks originated from the station, and the remaining 32 were launched from the airlocks of docked Space Shuttles.[77] The beta angle of the station had to be considered at all times during construction.[78]
The first module of the ISS, Zarya, was launched on 20 November 1998 on an autonomous Russian Proton rocket. It provided propulsion, attitude control, communications, electrical power, but lacked long-term life support functions. Two weeks later, a passive NASA module Unity was launched aboard Space Shuttle flight STS-88 and attached to Zarya by astronauts during EVAs. This module has two Pressurised Mating Adapter (PMAs), one connects permanently to Zarya, the other allowed the Space Shuttle to dock to the space station. At that time, the Russian station Mir was still inhabited, and the ISS remained uncrewed for two years. On 12 July 2000, Zvezda was launched into orbit. Preprogrammed commands on board deployed its solar arrays and communications antenna. It then became the passive target for a rendezvous with Zarya and Unity: it maintained a station-keeping orbit while the Zarya-Unity vehicle performed the rendezvous and docking via ground control and the Russian automated rendezvous and docking system. Zarya's computer transferred control of the station to Zvezda's computer soon after docking. Zvezda added sleeping quarters, a toilet, kitchen, CO2 scrubbers, dehumidifier, oxygen generators, exercise equipment, plus data, voice and television communications with mission control. This enabled permanent habitation of the station.[79][80]
The first resident crew, Expedition 1, arrived in November 2000 on Soyuz TM-31. At the end of the first day on the station, astronaut Bill Shepherd requested the use of the radio call sign "Alpha", which he and cosmonaut Krikalev preferred to the more cumbersome "International Space Station".[81] The name "Alpha" had previously been used for the station in the early 1990s,[82] and its use was authorised for the whole of Expedition 1.[83] Shepherd had been advocating the use of a new name to project managers for some time. Referencing a naval tradition in a pre-launch news conference he had said: "For thousands of years, humans have been going to sea in ships. People have designed and built these vessels, launched them with a good feeling that a name will bring good fortune to the crew and success to their voyage."[84] Yuri Semenov, the President of Russian Space Corporation Energia at the time, disapproved of the name "Alpha" as he felt that Mir was the first modular space station, so the names "Beta" or "Mir 2" for the ISS would have been more fitting.[83][85][86]
Expedition 1 arrived midway between the flights of STS-92 and STS-97. These two Space Shuttle flights each added segments of the station's Integrated Truss Structure, which provided the station with Ku-band communication for US television, additional attitude support needed for the additional mass of the USOS, and substantial solar arrays supplementing the station's existing 4 solar arrays.[87]
Over the next two year, the station continued to expand. A Soyuz-U rocket delivered the Pirs docking compartment. The Space Shuttles Discovery, Atlantis, and Endeavour delivered the Destiny laboratory and Quest airlock, in addition to the station's main robot arm, the Canadarm2, and several more segments of the Integrated Truss Structure.
The expansion schedule was interrupted by the Space Shuttle Columbia disaster in 2003 and a resulting hiatus in flights. The Space Shuttle was grounded until 2005 with STS-114 flown by Discovery.[88]
Assembly resumed in 2006 with the arrival of STS-115 with Atlantis, which delivered the station's second set of solar arrays. Several more truss segments and a third set of arrays were delivered on STS-116, STS-117, and STS-118. As a result of the major expansion of the station's power-generating capabilities, more pressurised modules could be accommodated, and the Harmony node and Columbus European laboratory were added. These were soon followed by the first two components of Kibō. In March 2009, STS-119 completed the Integrated Truss Structure with the installation of the fourth and final set of solar arrays. The final section of Kibō was delivered in July 2009 on STS-127, followed by the Russian Poisk module. The third node, Tranquility, was delivered in February 2010 during STS-130 by the Space Shuttle Endeavour, alongside the Cupola, followed in May 2010 by the penultimate Russian module, Rassvet. Rassvet was delivered by Space Shuttle Atlantis on STS-132 in exchange for the Russian Proton delivery of the US-funded Zarya module in 1998.[89] The last pressurised module of the USOS, Leonardo, was brought to the station in February 2011 on the final flight of Discovery, STS-133.[90] The Alpha Magnetic Spectrometer was delivered by Endeavour on STS-134 the same year.[91]
As of June 2011, the station consisted of 15 pressurised modules and the Integrated Truss Structure. Five modules are still to be launched, including the Nauka with the European Robotic Arm, the Prichal module, and two power modules called NEM-1 and NEM-2.[92] As of March 2019, Russia's future primary research module Nauka is set to launch in the summer of 2020, along with the European Robotic Arm which will be able to relocate itself to different parts of the Russian modules of the station.[93]
The gross mass of the station changes over time. The total launch mass of the modules on orbit is about 417,289 kg (919,965 lb) (as of 3 September 2011).[94] The mass of experiments, spare parts, personal effects, crew, foodstuff, clothing, propellants, water supplies, gas supplies, docked spacecraft, and other items add to the total mass of the station. Hydrogen gas is constantly vented overboard by the oxygen generators.
The ISS is a third generation[95] modular space station.[96] Modular stations can allow modules to be added to or removed from the existing structure, allowing greater flexibility.
Below is a diagram of major station components. The blue areas are pressurised sections accessible by the crew without using spacesuits. The station's unpressurised superstructure is indicated in red. Other unpressurised components are yellow. The Unity node joins directly to the Destiny laboratory. For clarity, they are shown apart.
Zarya
Zarya as seen by Space Shuttle Endeavour during STS-88
Zarya (Russian: Заря́, lit. 'Dawn'), also known as the Functional Cargo Block or FGB (from the Russian: "Функционально-грузовой блок", lit. 'Funktsionalno-gruzovoy blok' or ФГБ), is the first module of the ISS to be launched.[97] The FGB provided electrical power, storage, propulsion, and guidance to the ISS during the initial stage of assembly. With the launch and assembly in orbit of other modules with more specialized functionality, Zarya is now[when?] primarily used for storage, both inside the pressurized section and in the externally mounted fuel tanks. The Zarya is a descendant of the TKS spacecraft designed for the Russian Salyut program. The name Zarya, which means sunrise,[97] was given to the FGB because it signified the dawn of a new era of international cooperation in space. Although it was built by a Russian company, it is owned by the United States.[98]
Zarya was built from December 1994 to January 1998 at the Khrunichev State Research and Production Space Center (KhSC) in Moscow.[97]
Zarya was launched on 20 November 1998 on a Russian Proton rocket from Baikonur Cosmodrome Site 81 in Kazakhstan to a 400 km (250 mi) high orbit with a designed lifetime of at least 15 years. After Zarya reached orbit, STS-88 launched on 4 December 1998 to attach the Unity module.
Unity

Main article: Unity (ISS module)
The Unity connecting module, also known as Node 1, is the first U.S.-built component of the ISS. It connects the Russian and United States segments of the station, and is where crew eat meals together.
The module is cylindrical in shape, with six berthing locations (forward, aft, port, starboard, zenith, and nadir) facilitating connections to other modules. Unity measures 4.57 metres (15.0 ft) in diameter, is 5.47 metres (17.9 ft) long, made of steel, and was built for NASA by Boeing in a manufacturing facility at the Marshall Space Flight Center in Huntsville, Alabama. Unity is the first of the three connecting modules; the other two are Harmony and Tranquility.
Unity was carried into orbit as the primary cargo of the Space Shuttle Endeavour on STS-88, the first Space Shuttle mission dedicated to assembly of the station. On 6 December 1998, the STS-88 crew mated the aft berthing port of Unity with the forward hatch of the already orbiting Zarya module. This was the first connection made between two station modules.
Zvezda

Main article: Zvezda (ISS module)
Zvezda (Russian: Звезда́, meaning "star"), Salyut DOS-8, also known as the Zvezda Service Module, is a module of the ISS. It was the third module launched to the station, and provides all of the station's life support systems, some of which are supplemented in the USOS, as well as living quarters for two crew members. It is the structural and functional center of the Russian Orbital Segment, which is the Russian part of the ISS. Crew assemble here to deal with emergencies on the station.[99][100][101]
The basic structural frame of Zvezda, known as "DOS-8", was initially built in the mid-1980s to be the core of the Mir-2 space station. This means that Zvezda is similar in layout to the core module (DOS-7) of the Mir space station. It was in fact labeled as Mir-2 for quite some time in the factory. Its design lineage thus extends back to the original Salyut stations. The space frame was completed in February 1985 and major internal equipment was installed by October 1986.
The rocket used for launch to the ISS carried advertising; it was emblazoned with the logo of Pizza Hut restaurants,[102][103][104] for which they are reported to have paid more than US$1 million.[105] The money helped support Khrunichev State Research and Production Space Center and the Russian advertising agencies that orchestrated the event.[106]
On 26 July 2000, Zvezda became the third component of the ISS when it docked at the aft port of Zarya. (U.S. Unity module had already been attached to the Zarya.) Later in July, the computers aboard Zarya handed over ISS commanding functions to computers on Zvezda.[107]
Destiny

Main article: Destiny (ISS module)
The Destiny module, also known as the U.S. Lab, is the primary operating facility for U.S. research payloads aboard the International Space Station (ISS).[108][109] It was berthed to the Unity module and activated over a period of five days in February, 2001.[110] Destiny is NASA's first permanent operating orbital research station since Skylab was vacated in February 1974.
The Boeing Company began construction of the 14.5-tonne (32,000 lb) research laboratory in 1995 at the Michoud Assembly Facility and then the Marshall Space Flight Center in Huntsville, Alabama.[108] Destiny was shipped to the Kennedy Space Center in Florida in 1998, and was turned over to NASA for pre-launch preparations in August 2000. It launched on 7 February 2001 aboard the Space Shuttle Atlantis on STS-98.[110]
Quest
Quest Joint Airlock Module
Main article: Quest Joint Airlock
The Quest Joint Airlock, previously known as the Joint Airlock Module, is the primary airlock for the ISS. Quest was designed to host spacewalks with both Extravehicular Mobility Unit (EMU) spacesuits and Orlan space suits. The airlock was launched on STS-104 on 14 July 2001. Before Quest was attached, Russian spacewalks using Orlan suits could only be done from the Zvezda service module, and American spacewalks using EMUs were only possible when a Space Shuttle was docked. The arrival of Pirs docking compartment on September 16, 2001 provided another airlock from which Orlan spacewalks can be conducted.[citation needed]
Pirs and Poisk

Main articles: Pirs (ISS module) and Poisk (ISS module)
Pirs (Russian: Пирс, lit. 'pier') and Poisk (Russian: По́иск, lit. 'search') are Russian airlock modules, each having 2 identical hatches. An outward-opening hatch on the Mir space station failed after it swung open too fast after unlatching, because of a small amount of air pressure remaining in the airlock.[111] All EVA hatches on the ISS open inwards and are pressure-sealing. Pirs was used to store, service, and refurbish Russian Orlan suits and provided contingency entry for crew using the slightly bulkier American suits. The outermost docking ports on both airlocks allow docking of Soyuz and Progress spacecraft, and the automatic transfer of propellants to and from storage on the ROS.[112]
Pirs was launched on 14 September 2001, as ISS Assembly Mission 4R, on a Russian Soyuz-U rocket, using a modified Progress spacecraft, Progress M-SO1, as an upper stage. Poisk was launched on 10 November 2009[113][114] attached to a modified Progress spacecraft, called Progress M-MIM2, on a Soyuz-U rocket from Launch Pad 1 at the Baikonur Cosmodrome in Kazakhstan.
Harmony

Main article: Harmony (ISS module)
Harmony, also known as Node 2, is the "utility hub" of the ISS. It connects the laboratory modules of the United States, Europe and Japan, as well as providing electrical power and electronic data. Sleeping cabins for four of the six crew are housed here.[115]
Harmony was successfully launched into space aboard Space Shuttle flight STS-120 on October 23, 2007.[116][117] After temporarily being attached to the port side of the Unity node,[118][119] it was moved to its permanent location on the forward end of the Destiny laboratory on November 14, 2007.[120] Harmony added 2,666 cubic feet (75.5 m3) to the station's living volume, an increase of almost 20 percent, from 15,000 cu ft (420 m3) to 17,666 cu ft (500.2 m3). Its successful installation meant that from NASA's perspective, the station was "U.S. Core Complete".
Tranquility

Main article: Tranquility (ISS module)
Tranquility, also known as Node 3, is a module of the ISS. It contains environmental control systems, life support systems, a toilet, exercise equipment, and an observation cupola.
ESA and the Italian Space Agency had Tranquility built by Thales Alenia Space. A ceremony on November 20, 2009 transferred ownership of the module to NASA.[121] On February 8, 2010, NASA launched the module on the Space Shuttle's STS-130 mission.
Columbus
The Columbus module on the ISS
Main article: Columbus (ISS module)
Columbus is a science laboratory that is part of the ISS and is the largest single contribution to the ISS made by the European Space Agency (ESA).
Like the Harmony and Tranquility modules, the Columbus laboratory was constructed in Turin, Italy by Thales Alenia Space. The functional equipment and software of the lab was designed by EADS in Bremen, Germany. It was also integrated in Bremen before being flown to the Kennedy Space Center (KSC) in Florida in an Airbus Beluga. It was launched aboard Space Shuttle Atlantis on 7 February 2008 on flight STS-122. It is designed for ten years of operation. The module is controlled by the Columbus Control Centre, located at the German Space Operations Centre, part of the German Aerospace Center in Oberpfaffenhofen near Munich, Germany.
The European Space Agency has spent €1.4 billion (about US$2 billion) on building Columbus, including the experiments that will fly in it and the ground control infrastructure necessary to operate them.[122]

Main article: Cupola (ISS module)
The Cupola is an ESA-built observatory module of the ISS. Its name derives from the Italian word cupola, which means "dome". Its seven windows are used to conduct experiments, dockings and observations of Earth. It was launched aboard Space Shuttle mission STS-130 on 8 February 2010 and attached to the Tranquility (Node 3) module. With the Cupola attached, ISS assembly reached 85 percent completion. The Cupola's central window has a diameter of 80 cm (31 in).[124]
Rassvet

Rassvet (Russian: Рассве́т; lit. "dawn"), also known as the Mini-Research Module 1 (MRM-1) (Russian: Малый исследовательский модуль, МИМ 1) and formerly known as the Docking Cargo Module (DCM), is a component of the ISS. The module's design is similar to the Mir Docking Module launched on STS-74 in 1995. Rassvet is primarily used for cargo storage and as a docking port for visiting spacecraft. It was flown to the ISS aboard Space Shuttle Atlantis on the STS-132 mission on May 14, 2010,[125] and was connected to the ISS on May 18.[126] The hatch connecting Rassvet with the ISS was first opened on May 20.[127] On 28 June 2010, the Soyuz TMA-19 spacecraft performed the first docking with the module.[128]
Leonardo
Leonardo Permanent Multipurpose Module
Main article: Leonardo (ISS module)
The Leonardo Permanent Multipurpose Module (PMM) is a module of the ISS. It was flown into space aboard the Space Shuttle on STS-133 on 24 February 2011 and installed on 1 March. Leonardo is primarily used for storage of spares, supplies and waste on the ISS, which was until then stored in many different places within the space station. The Leonardo PMM was a Multi-Purpose Logistics Module (MPLM) before 2011, but was modified into its current configuration. It was formerly one of three MPLM used for bringing cargo to and from the ISS with the Space Shuttle. The module was named for Italian polymath Leonardo da Vinci.

The Bigelow Expandable Activity Module (BEAM) is an experimental expandable space station module developed by Bigelow Aerospace, under contract to NASA, for testing as a temporary module on the ISS from 2016 to at least 2020. It arrived at the ISS on 10 April 2016,[129] was berthed to the station on 16 April, and was expanded and pressurized on 28 May 2016.
International Docking Adapter
IDA-1 upright
Main article: International Docking Adapter
The International Docking Adapter (IDA) is a spacecraft docking system adapter developed to convert APAS-95 to the NASA Docking System (NDS)/International Docking System Standard (IDSS). An IDA is placed on each of the ISS' two open Pressurized Mating Adapters (PMAs), both of which are connected to the Harmony module.
IDA-1 was lost during the launch failure of SpaceX CRS-7 on 28 June 2015.[130][131][132]
IDA-2 was launched on SpaceX CRS-9 on 18 July 2016.[133] It was attached and connected to PMA-2 during a spacewalk on 19 August 2016.[134] First docking was achieved with the arrival of Crew Dragon Demo-1 on 3 March 2019. [135]
IDA-3 was launched on the SpaceX CRS-18 mission in July 2019.[136] IDA-3 is constructed mostly from spare parts to speed construction.[137] It was attached and connected to PMA-3 during a spacewalk on 21 August 2019. [138]
Unpressurised elements
ISS Truss Components breakdown showing Trusses and all ORUs in situ
The ISS has a large number of external components that do not require pressurisation. The largest of these is the Integrated Truss Structure (ITS), to which the station's main solar arrays and thermal radiators are mounted.[139] The ITS consists of ten separate segments forming a structure 108.5 m (356 ft) long.[3]
The station was intended to have several smaller external components, such as six robotic arms, three External Stowage Platforms (ESPs) and four ExPRESS Logistics Carriers (ELCs).[140][141] While these platforms allow experiments (including MISSE, the STP-H3 and the Robotic Refueling Mission) to be deployed and conducted in the vacuum of space by providing electricity and processing experimental data locally, their primary function is to store spare Orbital Replacement Units (ORUs). ORUs are parts that can be replaced when they fail or pass their design life, including pumps, storage tanks, antennas, and battery units. Such units are replaced either by astronauts during EVA or by robotic arms.[142] Several shuttle missions were dedicated to the delivery of ORUs, including STS-129,[143] STS-133[144] and STS-134.[145] As of January 2011, only one other mode of transportation of ORUs had been utilised – the Japanese cargo vessel HTV-2 – which delivered an FHRC and CTC-2 via its Exposed Pallet (EP).[146][needs update]
Construction of the Integrated Truss Structure over New Zealand.
There are also smaller exposure facilities mounted directly to laboratory modules; the Kibō Exposed Facility serves as an external 'porch' for the Kibō complex,[147] and a facility on the European Columbus laboratory provides power and data connections for experiments such as the European Technology Exposure Facility[148][149] and the Atomic Clock Ensemble in Space.[150] A remote sensing instrument, SAGE III-ISS, was delivered to the station in February 2017 aboard CRS-10,[151] and the NICER experiment was delivered aboard CRS-11 in June 2017.[152] The largest scientific payload externally mounted to the ISS is the Alpha Magnetic Spectrometer (AMS), a particle physics experiment launched on STS-134 in May 2011, and mounted externally on the ITS. The AMS measures cosmic rays to look for evidence of dark matter and antimatter.[153][154]
The commercial Bartolomeo External Payload Hosting Platform, manufactured by Airbus, is due to launch in May 2019 aboard a commercial ISS resupply vehicle and be attached to the European Columbus module. It will provide a further 12 external payload slots, supplementing the eight on the ExPRESS Logistics Carriers, ten on Kibō, and four on Columbus. The system is designed to be robotically serviced and will require no astronaut intervention. It is named after Christopher Columbus's younger brother.[155][156][157]
Robotic arms and cargo cranes
Commander Volkov stands on Pirs with his back to the Soyuz whilst operating the manual Strela crane holding photographer Kononenko.
Dextre, like many of the station's experiments and robotic arms, can be operated from Earth and perform tasks while the crew sleeps.
The Integrated Truss Structure serves as a base for the station's primary remote manipulator system, called the Mobile Servicing System (MSS), which is composed of three main components. Canadarm2, the largest robotic arm on the ISS, has a mass of 1,800 kilograms (4,000 lb) and is used to dock and manipulate spacecraft and modules on the USOS, hold crew members and equipment in place during EVAs and move Dextre around to perform tasks.[158] Dextre is a 1,560 kg (3,440 lb) robotic manipulator with two arms, a rotating torso and has power tools, lights and video for replacing orbital replacement units (ORUs) and performing other tasks requiring fine control.[159] The Mobile Base System (MBS) is a platform which rides on rails along the length of the station's main truss. It serves as a mobile base for Canadarm2 and Dextre, allowing the robotic arms to reach all parts of the USOS.[160] To gain access to the Russian Segment a grapple fixture was added to Zarya on STS-134, so that Canadarm2 can inchworm itself onto the ROS.[161] Also installed during STS-134 was the 15 m (50 ft) Orbiter Boom Sensor System (OBSS), which had been used to inspect heat shield tiles on Space Shuttle missions and can be used on station to increase the reach of the MSS.[161] Staff on Earth or the station can operate the MSS components via remote control, performing work outside the station without space walks.
Japan's Remote Manipulator System, which services the Kibō Exposed Facility,[162] was launched on STS-124 and is attached to the Kibō Pressurised Module.[163] The arm is similar to the Space Shuttle arm as it is permanently attached at one end and has a latching end effector for standard grapple fixtures at the other.
The European Robotic Arm, which will service the Russian Orbital Segment, will be launched alongside the Multipurpose Laboratory Module in 2017.[164] The ROS does not require spacecraft or modules to be manipulated, as all spacecraft and modules dock automatically and may be discarded the same way. Crew use the two Strela (Russian: Стрела́; lit. Arrow) cargo cranes during EVAs for moving crew and equipment around the ROS. Each Strela crane has a mass of 45 kg (99 lb).
Planned componments
Nauka

Main article: Nauka (ISS module)
Nauka (Russian: Нау́ка; lit. Science), also known as the Multipurpose Laboratory Module (MLM), (Russian: Многофункциональный лабораторный модуль, or МЛМ), is a component of the ISS which has not yet been launched into space. The MLM is funded by the Roscosmos State Corporation. In the original ISS plans, Nauka was to use the location of the Docking and Stowage Module. Later, the DSM was replaced by the Rassvet module and it was moved to Zarya's nadir port. Planners anticipate Nauka will dock at Zvezda's nadir port, replacing Pirs.[165]
The launch of Nauka, initially planned for 2007, has been repeatedly delayed for various reasons. As of September 2019, the launch to the ISS is assigned to no earlier than December 2020.[166] After this date, the warranties of some of Nauka's systems will expire.
Prichal
Mockup of the Prichal module at the Yuri Gagarin Cosmonaut Training Center
Main article: Prichal (ISS module)
Prichal, also known as Uzlovoy Module or UM (Russian: Узловой Модуль "Причал", Nodal Module Berth),[167] is a 4-tonne (8,800 lb)[168] ball-shaped module that will allow docking of two scientific and power modules during the final stage of the station assembly, and provide the Russian segment additional docking ports to receive Soyuz MS and Progress MS spacecraft. UM is due to be launched in 2022.[169] It will be integrated with a special version of the Progress cargo ship and launched by a standard Soyuz rocket, docking to the nadir port of the Nauka module. One port is equipped with an active hybrid docking port, which enables docking with the MLM module. The remaining five ports are passive hybrids, enabling docking of Soyuz and Progress vehicles, as well as heavier modules and future spacecraft with modified docking systems. The node module was intended to serve as the only permanent element of the cancelled OPSEK.[170][171]
Science Power Modules 1 and 2
Science Power Module 1 (SPM-1, also known as NEM-1) Science Power Module 2 (SPM-2, also known as NEM-2) are modules planned to arrive at the ISS in 2022.[169][172][173] It is going to dock to the Prichal module, which is planned to be attached to the Nauka module.[173] If Nauka is cancelled, then the Prichal, SPM-1, and SPM-2 would dock at the zenith port of Zvezda. SPM-1 and SPM-2 would also be required components for the OPSEK space station.[174]
Bishop Airlock Module
Main article: Bishop Airlock Module
The NanoRacks Bishop Airlock Module is a commercially-funded airlock module intended to be launched to the ISS on SpaceX CRS-21 in August 2020.[175][176] The module is being built by NanoRacks, Thales Alenia Space, and Boeing.[177] It will be used to deploy CubeSats, small satellites, and other external payloads for NASA, CASIS, and other commercial and governmental customers.[178]
Cancelled componments
The cancelled Habitation module under construction at Michoud in 1997
Several modules planned for the station were cancelled over the course of the ISS programme. Reasons include budgetary constraints, the modules becoming unnecessary, and station redesigns after the 2003 Columbia disaster. The US Centrifuge Accommodations Module would have hosted science experiments in varying levels of artificial gravity.[179] The US Habitation Module would have served as the station's living quarters. Instead, the sleep stations are now spread throughout the station.[180] The US Interim Control Module and ISS Propulsion Module would have replaced the functions of Zvezda in case of a launch failure.[181] Two Russian Research Modules were planned for scientific research.[182] They would have docked to a Russian Universal Docking Module.[183] The Russian Science Power Platform would have supplied power to the Russian Orbital Segment independent of the ITS solar arrays.
Systems
Life support
Main articles: ISS ECLSS and Chemical oxygen generator
The critical systems are the atmosphere control system, the water supply system, the food supply facilities, the sanitation and hygiene equipment, and fire detection and suppression equipment. The Russian Orbital Segment's life support systems are contained in the Zvezda service module. Some of these systems are supplemented by equipment in the USOS. The MLM Nauka laboratory has a complete set of life support systems.
Atmospheric control systems
A flowchart diagram showing the components of the ISS life support system.
The interactions between the components of the ISS Environmental Control and Life Support System (ECLSS)
The atmosphere on board the ISS is similar to the Earth's.[184] Normal air pressure on the ISS is 101.3 kPa (14.69 psi);[185] the same as at sea level on Earth. An Earth-like atmosphere offers benefits for crew comfort, and is much safer than a pure oxygen atmosphere, because of the increased risk of a fire such as that responsible for the deaths of the Apollo 1 crew.[186] Earth-like atmospheric conditions have been maintained on all Russian and Soviet spacecraft.[187]
The Elektron system aboard Zvezda and a similar system in Destiny generate oxygen aboard the station.[188] The crew has a backup option in the form of bottled oxygen and Solid Fuel Oxygen Generation (SFOG) canisters, a chemical oxygen generator system.[189] Carbon dioxide is removed from the air by the Vozdukh system in Zvezda. Other by-products of human metabolism, such as methane from the intestines and ammonia from sweat, are removed by activated charcoal filters.[189]
Part of the ROS atmosphere control system is the oxygen supply. Triple-redundancy is provided by the Elektron unit, solid fuel generators, and stored oxygen. The primary supply of oxygen is the Elektron unit which produces O
2 and H
2 by electrolysis of water and vents H2 overboard. The 1 kW (1.3 hp) system uses approximately one litre of water per crew member per day. This water is either brought from Earth or recycled from other systems. Mir was the first spacecraft to use recycled water for oxygen production. The secondary oxygen supply is provided by burning O
2-producing Vika cartridges (see also ISS ECLSS). Each 'candle' takes 5–20 minutes to decompose at 450–500 °C (842–932 °F), producing 600 litres (130 imp gal; 160 US gal) of O
2. This unit is manually operated.[190]
The US Orbital Segment has redundant supplies of oxygen, from a pressurised storage tank on the Quest airlock module delivered in 2001, supplemented ten years later by ESA-built Advanced Closed-Loop System (ACLS) in the Tranquility module (Node 3), which produces O
2 by electrolysis.[191] Hydrogen produced is combined with carbon dioxide from the cabin atmosphere and converted to water and methane.
Power and thermal control
Main articles: Electrical system of the International Space Station and External Active Thermal Control System
Russian solar arrays, backlit by sunset
One of the eight truss mounted pairs of USOS solar arrays
Double-sided solar arrays provide electrical power to the ISS. These bifacial cells collect direct sunlight on one side and light reflected off from the Earth on the other, and are more efficient and operate at a lower temperature than single-sided cells commonly used on Earth.[192]
The Russian segment of the station, like most spacecraft, uses 28 volt low voltage DC from four rotating solar arrays mounted on Zarya and Zvezda. The USOS uses 130–180 V DC from the USOS PV array, power is stabilised and distributed at 160 V DC and converted to the user-required 124 V DC. The higher distribution voltage allows smaller, lighter conductors, at the expense of crew safety. The two station segments share power with converters.
The USOS solar arrays are arranged as four wing pairs, for a total production of 75 to 90 kilowatts.[193] These arrays normally track the sun to maximise power generation. Each array is about 375 m2 (4,036 sq ft) in area and 58 m (190 ft) long. In the complete configuration, the solar arrays track the sun by rotating the alpha gimbal once per orbit; the beta gimbal follows slower changes in the angle of the sun to the orbital plane. The Night Glider mode aligns the solar arrays parallel to the ground at night to reduce the significant aerodynamic drag at the station's relatively low orbital altitude.[194]
The station originally used rechargeable nickel–hydrogen batteries (NiH
2) for continuous power during the 35 minutes of every 90-minute orbit that it is eclipsed by the Earth. The batteries are recharged on the day side of the orbit. They had a 6.5-year lifetime (over 37,000 charge/discharge cycles) and were regularly replaced over the anticipated 20-year life of the station.[195] Starting in 2016, the nickel–hydrogen batteries were replaced by lithium-ion batteries, which are expected to last until the end of the ISS program.[196]
The station's large solar panels generate a high potential voltage difference between the station and the ionosphere. This could cause arcing through insulating surfaces and sputtering of conductive surfaces as ions are accelerated by the spacecraft plasma sheath. To mitigate this, plasma contactor units (PCU)s create current paths between the station and the ambient plasma field.[197]
ISS External Active Thermal Control System (EATCS) diagram
The station's systems and experiments consume a large amount of electrical power, almost all of which is converted to heat. To keep the internal temperature within workable limits, a passive thermal control system (PTCS) is made of external surface materials, insulation such as MLI, and heat pipes. If the PTCS cannot keep up with the heat load, an External Active Thermal Control System (EATCS) maintains the temperature. The EATCS consists of an internal, non-toxic, water coolant loop used to cool and dehumidify the atmosphere, which transfers collected heat into an external liquid ammonia loop. From the heat exchangers, ammonia is pumped into external radiators that emit heat as infrared radiation, then back to the station.[198] The EATCS provides cooling for all the US pressurised modules, including Kibō and Columbus, as well as the main power distribution electronics of the S0, S1 and P1 trusses. It can reject up to 70 kW. This is much more than the 14 kW of the Early External Active Thermal Control System (EEATCS) via the Early Ammonia Servicer (EAS), which was launched on STS-105 and installed onto the P6 Truss.[199]
Communications and computers

The communications systems used by the ISS
* Luch satellite and the Space Shuttle are not currently[when?] in use
Radio communications provide telemetry and scientific data links between the station and Mission Control Centres. Radio links are also used during rendezvous and docking procedures and for audio and video communication between crew members, flight controllers and family members. As a result, the ISS is equipped with internal and external communication systems used for different purposes.[200]
The Russian Orbital Segment communicates directly with the ground via the Lira antenna mounted to Zvezda.[6][201] The Lira antenna also has the capability to use the Luch data relay satellite system.[6] This system fell into disrepair during the 1990s, and so was not used during the early years of the ISS,[6][202][203] although two new Luch satellites—Luch-5A and Luch-5B—were launched in 2011 and 2012 respectively to restore the operational capability of the system.[204] Another Russian communications system is the Voskhod-M, which enables internal telephone communications between Zvezda, Zarya, Pirs, Poisk, and the USOS and provides a VHF radio link to ground control centres via antennas on Zvezda's exterior.[205]
The US Orbital Segment (USOS) makes use of two separate radio links mounted in the Z1 truss structure: the S band (audio) and Ku band (audio, video and data) systems. These transmissions are routed via the United States Tracking and Data Relay Satellite System (TDRSS) in geostationary orbit, allowing for almost continuous real-time communications with NASA's Mission Control Center (MCC-H) in Houston.[22][6][200] Data channels for the Canadarm2, European Columbus laboratory and Japanese Kibō modules were originally also routed via the S band and Ku band systems, with the European Data Relay System and a similar Japanese system intended to eventually complement the TDRSS in this role.[22][206] Communications between modules are carried on an internal wireless network.[207]
An array of laptops in the US lab
Laptop computers surround the Canadarm2 console
UHF radio is used by astronauts and cosmonauts conducting EVAs and other spacecraft that dock to or undock from the station.[6] Automated spacecraft are fitted with their own communications equipment; the ATV uses a laser attached to the spacecraft and the Proximity Communications Equipment attached to Zvezda to accurately dock with the station.[208][209]
The ISS is equipped with about 100 IBM/Lenovo ThinkPad and HP ZBook 15 laptop computers. The laptops have run Windows 95, Windows 2000, Windows XP, Windows 7, Windows 10 and Linux operating systems.[210] Each computer is a commercial off-the-shelf purchase which is then modified for safety and operation including updates to connectors, cooling and power to accommodate the station's 28V DC power system and weightless environment. Heat generated by the laptops does not rise but stagnates around the laptop, so additional forced ventilation is required. Laptops aboard the ISS are connected to the station's wireless LAN via Wi-Fi, which connects to the ground via Ku band. This provides speeds of 10 Mbit/s download and 3 Mbit/s upload from the station, comparable to home DSL connection speeds.[211][212] Laptop hard drives occasionally fail and must be replaced.[213] Other computer hardware failures include instances in 2001, 2007 and 2017; some of these failures have required EVAs to replace computer modules in externally mounted devices.[214][215][216][217]
The operating system used for key station functions is the Debian Linux distribution.[218] The migration from Microsoft Windows was made in May 2013 for reasons of reliability, stability and flexibility.[219]
In 2017, an SG100 Cloud Computer was launched to the ISS as part of OA-7 mission.[220] It was manufactured by NCSIST and designed in collaboration with Academia Sinica, and National Central University under contract for NASA.[221]
Operations
Expeditions and private flights

ISS was slowly assembled over a decade of spaceflights and crews
Each permanent crew is given an expedition number. Expeditions run up to six months, from launch until undocking, an 'increment' covers the same time period, but includes cargo ships and all activities. Expeditions 1 to 6 consisted of 3 person crews, Expeditions 7 to 12 were reduced to the safe minimum of two following the destruction of the NASA Shuttle Columbia. From Expedition 13 the crew gradually increased to 6 around 2010.[222][223] With the arrival of the US Commercial Crew vehicles in the late 2010s, expedition size may be increased to seven crew members, the number ISS is designed for.[224][225]
Gennady Padalka, member of Expeditions 9, 19/20, 31/32, and 43/44, and Commander of Expedition 11, has spent more time in space than anyone else, a total of 878 days, 11 hours, and 29 minutes.[226] Peggy Whitson has spent the most time in space of any American, totalling 665 days, 22 hours, and 22 minutes during her time on Expeditions 5, 16, and 50/51/52.[227]
Travellers who pay for their own passage into space are termed spaceflight participants by Roscosmos and NASA, and are sometimes referred to as space tourists, a term they generally dislike.[note 1] All seven were transported to the ISS on Russian Soyuz spacecraft. When professional crews change over in numbers not divisible by the three seats in a Soyuz, and a short-stay crewmember is not sent, the spare seat is sold by MirCorp through Space Adventures. When the space shuttle retired in 2011, and the station's crew size was reduced to 6, space tourism was halted, as the partners relied on Russian transport seats for access to the station. Soyuz flight schedules increase after 2013, allowing 5 Soyuz flights (15 seats) with only two expeditions (12 seats) required.[233] The remaining seats are sold for around US$40 million to members of the public who can pass a medical exam. ESA and NASA criticised private spaceflight at the beginning of the ISS, and NASA initially resisted training Dennis Tito, the first person to pay for his own passage to the ISS.[note 2]
Anousheh Ansari became the first Iranian in space and the first self-funded woman to fly to the station. Officials reported that her education and experience make her much more than a tourist, and her performance in training had been "excellent."[234] Ansari herself dismisses the idea that she is a tourist. She did Russian and European studies involving medicine and microbiology during her 10-day stay. The documentary Space Tourists follows her journey to the station, where she fulfilled "an age-old dream of man: to leave our planet as a "normal person" and travel into outer space."[235]
In 2008, spaceflight participant Richard Garriott placed a geocache aboard the ISS during his flight.[236] This is currently the only non-terrestrial geocache in existence.[237] At the same time, the Immortality Drive, an electronic record of eight digitised human DNA sequences, was placed aboard the ISS.[238]
Orbit
Graph showing the changing altitude of the ISS from November 1998 until November 2018
Animation of ISS orbit from 14 September 2018 to 14 November 2018. Earth is not shown.
The ISS is maintained in a nearly circular orbit with a minimum mean altitude of 330 km (205 mi) and a maximum of 410 km (255 mi), in the centre of the thermosphere, at an inclination of 51.6 degrees to Earth's equator. This orbit was selected because it is the lowest inclination that can be directly reached by Russian Soyuz and Progress spacecraft launched from Baikonur Cosmodrome at 46° N latitude without overflying China or dropping spent rocket stages in inhabited areas.[239][240] It travels at an average speed of 27,724 kilometres per hour (17,227 mph), and completes 15.54 orbits per day (93 minutes per orbit).[2][14] The station's altitude was allowed to fall around the time of each NASA shuttle flight to permit heavier loads to be transferred to the station. After the retirement of the shuttle, the nominal orbit of the space station was raised in altitude.[241][242] Other, more frequent supply ships do not require this adjustment as they are substantially higher performance vehicles.[28][243]
Orbital boosting can be performed by the station's two main engines on the Zvezda service module, or Russian or European spacecraft docked to Zvezda's aft port. The ATV is constructed with the possibility of adding a second docking port to its aft end, allowing other craft to dock and boost the station. It takes approximately two orbits (three hours) for the boost to a higher altitude to be completed.[243] Maintaining ISS altitude uses about 7.5 tonnes of chemical fuel per annum[244] at an annual cost of about $210 million.[245]

The Russian Orbital Segment contains the Data Management System, which handles Guidance, Navigation and Control (ROS GNC) for the entire station.[246] Initially, Zarya, the first module of the station, controlled the station until a short time after the Russian service module Zvezda docked and was transferred control. Zvezda contains the ESA built DMS-R Data Management System.[247] Using two fault-tolerant computers (FTC), Zvezda computes the station's position and orbital trajectory using redundant Earth horizon sensors, Solar

Samarkand is a city in southeastern Uzbekistan and among the oldest continuously inhabited cities in Central Asia. Samarkand is the capital of the Samarkand Region and a district-level city, that includes the urban-type settlements Kimyogarlar, Farhod and Khishrav. With 551,700 inhabitants (2021)] it is the third-largest city in Uzbekistan.
There is evidence of human activity in the area of the city dating from the late Paleolithic Era. Though there is no direct evidence of when Samarkand was founded, several theories propose that it was founded between the 8th and 7th centuries BC. Prospering from its location on the Silk Road between China, Persia and Europe, at times Samarkand was one of the largest cities in Central Asia, and was an important city of the empires of Greater Iran. By the time of the Persian Achaemenid Empire, it was the capital of the Sogdian satrapy. The city was conquered by Alexander the Great in 329 BC, when it was known as Markanda, which was rendered in Greek as Μαράκανδα. The city was ruled by a succession of Iranian and Turkic rulers until it was conquered by the Mongols under Genghis Khan in 1220.
The city is noted as a centre of Islamic scholarly study and the birthplace of the Timurid Renaissance. In the 14th century, Timur made it the capital of his empire and the site of his mausoleum, the Gur-e Amir. The Bibi-Khanym Mosque, rebuilt during the Soviet era, remains one of the city's most notable landmarks. Samarkand's Registan square was the city's ancient centre and is bounded by three monumental religious buildings. The city has carefully preserved the traditions of ancient crafts: embroidery, goldwork, silk weaving, copper engraving, ceramics, wood carving, and wood painting. In 2001, UNESCO added the city to its World Heritage List as Samarkand – Crossroads of Cultures.
Modern Samarkand is divided into two parts: the old city, which includes historical monuments, shops, and old private houses; and the new city, which was developed during the days of the Russian Empire and Soviet Union and includes administrative buildings along with cultural centres and educational institutions. On 15 and 16 September 2022, the city hosted the 2022 SCO summit.
Samarkand has a multicultural and plurilingual history that was significantly modified by the process of national delimitation in Central Asia. Many inhabitants of the city are native or bilingual speakers of the Tajik language, whereas Uzbek is the official language and Russian is also widely used in the public sphere, as per Uzbekistan's language policy.
In a culture that is continuously accelerating, filters have become a primal commodity. We use them both to open and to close ourselves to or from any kind of possible information. Filters are ubiquitous. However, we only realize their presence when we lack them or when they fail our expectations. On the other hand, modern digital cultures are inseparable from keywords like functionality, s...moothness, order and progress. Interaction designers, programmers and interface developers all work together to understand and execute these mantras. But to really understand these keywords, they have to be defined in relation to what they are not. A successful product designer does not design for the average customer, but instead for the marginal, extreme customer; because when taking the margins as the rule, the middle will take care of itself. ! This is why studying the qualities of disfunction, irregularities, breaks, disorder, damage or even demolition are as important in the development of a new technological product as the researching of its perfect flows and this is also one of the reasons why I think it is important to study failure. The concepts of perfection and failure are a tradeoff of each other. If we want to understand and pursue perfection - we can find this in the pursuit of failure.
The exhibition Filtering Failure investigates (the connections between) the procedural terms ‘filtering’ and ‘failure’ and how in (lo-fi) digital arts these terms are being re-invented and re-used. The exhibition asks how Filtering and Failure co-exist; and how these processes influence each other.
The exhibition includes new and older works from the avant-garde of glitch artists. These works show the filtering of failure as a generative process, but also to unfold a genre that includes many the different envelopes of personal ways of dealing with failure.
Filering Failure is curated by Julian van Aalderen and Rosa Menkman.

Why wear a continuous glucose monitor?
Too much glucose in your bloodstream is toxic, too little is fatal. Our bodies prioritize by keeping us sick and alive (with obesity, high blood pressure, heart disease, diabetes) in the former condition, and manufacturing glucose in the latter. Because of this, too much blood glucose is common, too little blood glucose is rare.
A continuous glucose monitor is another - provides minute by minute information about how the body handles this tightly controlled metabolite. Currently, these are used for people with diabetes (unfortunately a greater % of the population), eventually, as is being discussed, this technology may be embedded in the Apple Watch.
In terms of the product, I am fascinated by the color combinations chosen - the blue and yellow are clearly a complementary pair, making the device itself a color harmony.

The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. The surrounding area is contained within the Baaj Nwaavjo I'tah Kukveni – Ancestral Footprints of the Grand Canyon National Monument. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery.
Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.
For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site, and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.

Grand Canyon National Park is a national park of the United States located in northwestern Arizona, the 15th site to have been named as a national park. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which is often considered one of the Wonders of the World. The park, which covers 1,217,262 acres (1,901.972 sq mi; 4,926.08 km2) of unincorporated area in Coconino and Mohave counties, received more than 4.7 million recreational visitors in 2023. The Grand Canyon was designated a World Heritage Site by UNESCO in 1979. The park celebrated its 100th anniversary on February 26, 2019.

Douglas Historic Cemeteries - Pioneers of Alaska
A 1995 historic sites and structures inventory identified three non-continuous cemetery sites on Douglas, known generally as the Douglas Catholic Cemetery, Eagles Cemetery, and the Douglas Indian Cemetery.
All three cemeteries are located along Douglas Highway within a mile and a half of each other. While documenting the cemeteries, it was uncovered that two of the cemeteries were actually made up of a grouping of smaller cemeteries.
The Catholic Cemetery includes the Catholic Cemetery, the Odd Fellows Cemetery, the Masons Cemetery, the Native Cemetery, the Asian Cemetery, and the Russian Orthodox Cemetery.
The Eagles Cemetery is made up of the Douglas City Cemetery, the Eagles Cemetery, and the Servian Cemetery.
There was no cemetery in Douglas in the early 1880's and 1890's. In 1887 there were no newspapers except in Juneau and little mention was made of deaths in Douglas or Treadwell, unless it was a major mine accident. The Douglas Island News was established in 1898 and vital statistics were recorded.
One article states that Douglas people were buried in Juneau before 1900. Some may have been buried in the "Ridge Cemetery" (Chicken Ridge) as early as 1887 and in the Evergreen Cemetery which was developed in 1888-89. A few deaths were recorded in 1899, and in August of 1900 people were reported as being "buried in the old cemetery." It is not clear whether or not they meant Douglas. There may have been some burials near the outskirts of town before the establishment of the "new" cemetery.
The first issue of the Douglas Island News in 1898 stated that a movement to start a cemetery occurred at a public meeting. In the August 1900 issue the editor commented, "In constructing a cemetery on Douglas Island a very peculiar condition presents itself Will Douglas citizens bury their dead on Douglas Island?" He goes on to say that there "are numerous graves tended and fenced by Douglas relatives (in Juneau) and would families want to be separated." The old cemetery was known all over Alaska as the Juneau-Douglas Cemetery. Yet the citizens of Douglas wanted their own burial ground.
In 1899 mining engineer W.A Sanders, W.A Thompson, and Minnie Ross Holman applied for a patent to mining claims which took in the northwest end of the town of Douglas, including streets and buildings. The ground consisted of over 50 acres which included 13 lode claims and some mill sites. A committee was formed to protest this patent.
Sanders agreed that if the committee did not protest his application for patent he would deed back "all lots, easement of streets, etc. and other points in which his patent interfered with the town of Douglas." This was later agreed to in writing.
The committee asked for ground for a cemetery. Sanders agreed to give the people of Douglas "the dry knoll this side of Lawson Creek" if they would not object to his patent.
He also agreed to build a road to the grounds, but declined to put it in writing and said his word was good.
Immediately after the meeting, a Cemetery Committee consisting of P.H. Fox, M.J. O'Connor, Reverand Peplogle and W.C. Boyd took possession of the knoll and ran a line from Third Street in Douglas to the area.
Shortly after Sander's verbal agreement the Cemetery Committee hired three men and started clearing a trail, which later became a gravel road, from Third Street in Douglas to the knoll.
The land claimed was "to the left' of the gravel road on the bench from the gulch where the road strikes the bench, to Lawson Creek." The road was approximately one-half mile in a straight line. About 30 feet of planking was done from the end of Third Street to the "Old Indian Graveyard" (Douglas Indian Cemetery) and three small bridges were constructed. Two acres were cleared and between four and five acres were enclosed by a wire fence. This description fits the location of the current City Cemetery.
Though W.A Sanders was a noted mining engineer, it was felt among the citizens of Douglas the Sanders' claims were not valid because he was a resident of Nova Scotia, Canada. Apparently the patent office did not agree. In 1900, Sanders obtained a patent to part of the mining claims.
He kept his written word and deeded back the land and buildings, but refused to honor his verbal agreement regarding the cemetery, in fact he denied making it.
Eventually he admitted he had made the agreement but "he wasn't going to buy land and pay out money for it and then give it away." Mr. Sanders was informed that the people of Douglas had earned the cemetery ground because they did not interfere with his patent. They even offered to pay him the government price of $5.00 an acre. He did not feel that was enough. It is not stated what the final outcome was.
Sanders did post no trespassing notices as late as 1903 threatening to prosecute any person using the ground for burial purposes, but they soon disappeared. Douglas residents claimed that they had been in "legal and peaceable possession of the premises for about three years."
Fund drives began in 1900 to raise money to pay for the gravel road and other improvements. Over $1,000 was collected in two months through musical benefits and subscriptions. Donations were as high as $30 per individual when the average day's wage was around $3.00.
The cemetery land was eventually divided into nine sections which were sold to various groups. The main ones being the City Cemetery, Eagles, Odd Fellows, Masons, and Catholics. Smaller sections were dedicated to the Servians, Asians, Natives, Russian Orthodox and one source claims there were separate sections for prostitutes and suicides.
In November 1900 pioneer Douglas resident W.C. Boyd was appointed clerk for the Cemetery Committee and was to keep all records. He also was in charge of the road gang and later appointed as grave digger because previous diggers were not "observing the plan of the streets and alleys as marked out."
Persons wishing to bury their dead in the Douglas Cemetery were required to apply for a permit with the description of the deceased, name, age, and birth place. Records were kept for future use.
A charge of $5.00 was made for a burial permit and a plot (this fee was still in affect as late as 1933). Families could secure a lot sufficient for five burials for $10.00. Societies (lodges, etc.) could obtain a lot from $50.00 upwards, depending upon the size. The ground was to be cleared and fenced and a yearly fee was charged for road repairs and other maintenance.
One source reported that in 1907 there was unrest at Treadwell because of rumors that if a man died and had no relatives, his body would end up in the mill tailings piles. That same year John Yamanoi, a Japanese kitchen worker was murdered. A week later the "Treadwell Funeral Riots" began. The men demanded special caskets and funerals complete with the Treadwell Band, marked graves and notification of their deaths to their relatives. In 1913 the Treadwell Company agreed to funeral expenses not to exceed $125 per interment.
There were over eight mining related deaths at the Treadwell mines in 1901. The greatest loss of life was on March 2, 1910 at 11:30 PM on the 1,100 foot level of the Mexican Mine when the powder magazine exploded. The men were gathered at their station wiring to be hoisted to the surface for their midnight meal. All 36 men died except one who was badly injured. At the 900 foot level a man was killed by the shock of the explosion and others were injured.
Numerous graves have been found in the city cemetery and one in the native cemetery of these mining accident victims. The average age of the 1910 victims was twenty and most of them appeared to be single. The men were from all over the world including Austria, Italy, England, Norway, and Finland Only two were listed as being from the United States.
There were no morticians as we know them today. Cabinet shops were established that included the making of furniture and caskets. The owners of these shops became the undertakers for the town. Advertisements were in the Douglas Island News reading "Undertaking ... Manufacturers of Furniture, Carpentering, Jobbing, Store & Office Fixtures."
Others read, "Douglas Undertaking Parlors, Funeral Directors and Embalmers." Some of these undertakers were H.V. Sully, POA Juneau Igloo Charter Member John.A McKanna, T.P. Sheldon, and L.G. Thomas and Merle Thomas. Some of the deceased were shipped to Juneau to C.W. Young and POA Juneau Igloo President Charles W. Carter and then returned to Douglas for burial.
Laura McCarley, author of "Treadwell, Alaska" says that blanket burials in unmarked graves were the standard practice of the mining companies. She also reports that the new Douglas cemetery, presumably the City Cemetery, was laid out in 20' by 20' plots, with streets and alley ways and that a German cabinet maker and hardware merchant, John Feusi, went into
the undertaking business. Reportedly a partially blind Tlingit from the Taku Village, Frank Weaver, was carving tombstones out of Tolkeen Marble.
An undetermined number of graves in the Servian, Asian, and Native cemeteries were moved when the Bureau of Public Roads constructed Douglas Highway to Cowee Creek in 1934. A news article stated that the bodies were interred in the present City Cemetery.
In February 1937 disaster struck as a fire burned businesses on Front Street and moved up D Street into the heart of the townsite along Third Street. Blocks of business property were destroyed along with the school, city offices, churches, and many residences. Among the items burned were the city records dating back to the 1890's.
Among them were vital statistics records from 1909 to 1920; old cemetery records by W. Boyd from 1900 to 1910; numerous burial lists, records and papers; revised cemetery record 1927; and chart and burial lot plat of the cemetery.
In 1967, due to a road project, eight graves containing 13 bodies in the Douglas Indian Cemetery were removed and interred at Evergreen Cemetery in Juneau.
In 1972 graves were disturbed at the Eagles Cemetery due to the widening of Douglas Highway. About 25 graves were moved to Alaska Memorial Park in the Mendenhall Valley. The exact number of burial sites disturbed or moved is difficult to document as the records are not readily accessible or don't exist.
In the early 1970's the City and Borough of Juneau agreed to survey cemetery land in Douglas as part of an effort to investigate, clear title to the property, and gather information to acquire, survey and maintain the cemeteries.
One assemblyman agreed that an inventory should be made and that the city should assume responsibility for the Douglas land. It was even suggested that additional land around the cemetery be purchased to accommodate new burial sites.
It was also suggested that individuals who had relatives in the cemetery be asked to maintain the grave sites or donate money to have them maintained.
The Ross Estate was to be contacted and asked for transfer of ownership of the cemetery land. If they could not be contacted, a quiet title action was to be initiated and the grave sites were to be inventoried. There is no evidence that the Ross Estate was ever contacted and the quiet title action has never been completed.
In July of 1979 foundations were being constructed for a private home allegedly on the western edge of the City Cemetery. The owners of the property in question reportedly took extraordinary measures to make certain there was no problem. A group of Douglas residents were extremely upset, and tried to halt construction.
The attorney for the individuals said there was no evidence that the site was part of the Douglas Cemetery, even though the house is surrounded by graves.
Investigations were made by the Alaska State Troopers and the State Attorney General's office. An archaeologist was also called in to investigate.
It was later proved that the house was not within the cemetery boundaries. The proof sought was a quiet title action, dated in 1964, by the O.T. Corporation versus the City of Douglas that indicated the land was not part of a cemetery.
In the judgement and decree of the court the O.T. Corporation got title to the lot which was eventually sold. The lot was described as adjacent to but not in a cemetery.
During the controversy, numerous Douglas residents turned out to clean away the brush and debris in the Douglas Cemetery. Residents also asked the Borough Assembly to stop the construction project, but this request was turned down.

High Dynamic Range (HDR)
High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different, narrower range, exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, referred to as LDR, resulting in the loss of detail in highlights or shadows.
The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs. HDR images can also be acquired using special image sensors, such as an oversampled binary image sensor.
Due to the limitations of printing and display contrast, the extended luminosity range of an HDR image has to be compressed to be made visible. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved local contrast (or exaggerated for artistic effect).
In photography, dynamic range is measured in exposure value (EV) differences (known as stops). An increase of one EV, or 'one stop', represents a doubling of the amount of light. Conversely, a decrease of one EV represents a halving of the amount of light. Therefore, revealing detail in the darkest of shadows requires high exposures, while preserving detail in very bright situations requires very low exposures. Most cameras cannot provide this range of exposure values within a single exposure, due to their low dynamic range. High-dynamic-range photographs are generally achieved by capturing multiple standard-exposure images, often using exposure bracketing, and then later merging them into a single HDR image, usually within a photo manipulation program). Digital images are often encoded in a camera's raw image format, because 8-bit JPEG encoding does not offer a wide enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).
Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must first be digitized, so that they can later be processed using software HDR methods.
In most imaging devices, the degree of exposure to light applied to the active element (be it film or CCD) can be altered in one of two ways: by either increasing/decreasing the size of the aperture or by increasing/decreasing the time of each exposure. Exposure variation in an HDR set is only done by altering the exposure time and not the aperture size; this is because altering the aperture size also affects the depth of field and so the resultant multiple images would be quite different, preventing their final combination into a single HDR image.
An important limitation for HDR photography is that any movement between successive images will impede or prevent success in combining them afterwards. Also, as one must create several images (often three or five and sometimes more) to obtain the desired luminance range, such a full 'set' of images takes extra time. HDR photographers have developed calculation methods and techniques to partially overcome these problems, but the use of a sturdy tripod is, at least, advised.
Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging method grows, several camera manufactures are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95 and Canon PowerShot S100 offer similar features in a smaller format.. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the accent being on retaing a realistic effect . Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.
Camera characteristics such as gamma curves, sensor resolution, noise, photometric calibration and color calibration affect resulting high-dynamic-range images.
Color film negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range
Tone mapping
Tone mapping reduces the dynamic range, or contrast ratio, of an entire image while retaining localized contrast. Although it is a distinct operation, tone mapping is often applied to HDRI files by the same software package.
Several software applications are available on the PC, Mac and Linux platforms for producing HDR files and tone mapped images. Notable titles include
Adobe Photoshop
Aurora HDR
Dynamic Photo HDR
HDR Efex Pro
HDR PhotoStudio

Information stored in high-dynamic-range images typically corresponds to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors as they should appear on a monitor or a paper print. Therefore, HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information stored in the fixed number of bits), which is usually called gamma encoding or gamma correction. The values stored for HDR images are often gamma compressed (power law) or logarithmically encoded, or floating-point linear values, since fixed-point linear encodings are increasingly inefficient over higher dynamic ranges.
HDR images often don't use fixed ranges per color channel—other than traditional images—to represent many more colors over a much wider dynamic range. For that purpose, they don't use integer values to represent the single color channels (e.g., 0-255 in an 8 bit per pixel interval for red, green and blue) but instead use a floating point representation. Common are 16-bit (half precision) or 32-bit floating point numbers to represent HDR pixels. However, when the appropriate transfer function is used, HDR pixels for some applications can be represented with a color depth that has as few as 10–12 bits for luminance and 8 bits for chrominance without introducing any visible quantization artifacts.
History of HDR photography
The idea of using several exposures to adequately reproduce a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, as the luminosity range was too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive.
Mid 20th century
Manual tone mapping was accomplished by dodging and burning – selectively increasing or decreasing the exposure of regions of the photograph to yield better tonality reproduction. This was effective because the dynamic range of the negative is significantly higher than would be available on the finished positive paper print when that is exposed via the negative in a uniform manner. An excellent example is the photograph Schweitzer at the Lamp by W. Eugene Smith, from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to reproduce the tonal range of the scene, which ranges from a bright lamp (relative to the scene) to a dark shadow.
Ansel Adams elevated dodging and burning to an art form. Many of his famous prints were manipulated in the darkroom with these two methods. Adams wrote a comprehensive book on producing prints called The Print, which prominently features dodging and burning, in the context of his Zone System.
With the advent of color photography, tone mapping in the darkroom was no longer possible due to the specific timing needed during the developing process of color film. Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods.
Color film capable of directly recording high-dynamic-range images was developed by Charles Wyckoff and EG&G "in the course of a contract with the Department of the Air Force". This XR film had three emulsion layers, an upper layer having an ASA speed rating of 400, a middle layer with an intermediate rating, and a lower layer with an ASA rating of 0.004. The film was processed in a manner similar to color films, and each layer produced a different color. The dynamic range of this extended range film has been estimated as 1:108. It has been used to photograph nuclear explosions, for astronomical photography, for spectrographic research, and for medical imaging. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid-1950s.
Late 20th century
Georges Cornuéjols and licensees of his patents (Brdi, Hymatom) introduced the principle of HDR video image, in 1986, by interposing a matricial LCD screen in front of the camera's image sensor, increasing the sensors dynamic by five stops. The concept of neighborhood tone mapping was applied to video cameras by a group from the Technion in Israel led by Dr. Oliver Hilsenrath and Prof. Y.Y.Zeevi who filed for a patent on this concept in 1988.
In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera that combined two images captured by a sensor3435 or simultaneously3637 by two sensors of the camera. This process is known as bracketing used for a video stream.
In 1991, the first commercial video camera was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Georges Cornuéjols.
Also in 1991, Georges Cornuéjols introduced the HDR+ image principle by non-linear accumulation of images to increase the sensitivity of the camera: for low-light environments, several successive images are accumulated, thus increasing the signal to noise ratio.
In 1993, another commercial medical camera producing an HDR video image, by the Technion.
Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations (across the entire image), and then tone mapping the result. Global HDR was first introduced in 19931 resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995 by Steve Mann and Rosalind Picard.
On October 28, 1998, Ben Sarao created one of the first nighttime HDR+G (High Dynamic Range + Graphic image)of STS-95 on the launch pad at NASA's Kennedy Space Center. It consisted of four film images of the shuttle at night that were digitally composited with additional digital graphic elements. The image was first exhibited at NASA Headquarters Great Hall, Washington DC in 1999 and then published in Hasselblad Forum, Issue 3 1993, Volume 35 ISSN 0282-5449.
The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Steve Mann developed and patented the global-HDR method for producing digital images having extended dynamic range at the MIT Media Laboratory. Mann's method involved a two-step procedure: (1) generate one floating point image array by global-only image operations (operations that affect all pixels identically, without regard to their local neighborhoods); and then (2) convert this image array, using local neighborhood processing (tone-remapping, etc.), into an HDR image. The image array generated by the first step of Mann's process is called a lightspace image, lightspace picture, or radiance map. Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision, and other image processing operations.
21st century
In 2005, Adobe Systems introduced several new features in Photoshop CS2 including Merge to HDR, 32 bit floating point image support, and HDR tone mapping.
On June 30, 2016, Microsoft added support for the digital compositing of HDR images to Windows 10 using the Universal Windows Platform.
HDR sensors
Modern CMOS image sensors can often capture a high dynamic range from a single exposure. The wide dynamic range of the captured image is non-linearly compressed into a smaller dynamic range electronic representation. However, with proper processing, the information from a single exposure can be used to create an HDR image.
Such HDR imaging is used in extreme dynamic range applications like welding or automotive work. Some other cameras designed for use in security applications can automatically provide two or more images for each frame, with changing exposure. For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. Some of the sensor may even combine the two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.

Infrared Photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs. The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared.
The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering, respectively, compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black.
Until the early 20th century, infrared photography was not possible because silver halide emulsions are not sensitive to longer wavelengths than that of blue light (and to a lesser extent, green light) without the addition of a dye to act as a color sensitizer. The first infrared photographs (as distinct from spectrographs) to be published appeared in the February 1910 edition of The Century Magazine and in the October 1910 edition of the Royal Photographic Society Journal to illustrate papers by Robert W. Wood, who discovered the unusual effects that now bear his name. The RPS co-ordinated events to celebrate the centenary of this event in 2010. Wood's photographs were taken on experimental film that required very long exposures; thus, most of his work focused on landscapes. A further set of infrared landscapes taken by Wood in Italy in 1911 used plates provided for him by CEK Mees at Wratten & Wainwright. Mees also took a few infrared photographs in Portugal in 1910, which are now in the Kodak archives.
Infrared-sensitive photographic plates were developed in the United States during World War I for spectroscopic analysis, and infrared sensitizing dyes were investigated for improved haze penetration in aerial photography. After 1930, new emulsions from Kodak and other manufacturers became useful to infrared astronomy.
Infrared photography became popular with photography enthusiasts in the 1930s when suitable film was introduced commercially. The Times regularly published landscape and aerial photographs taken by their staff photographers using Ilford infrared film. By 1937 33 kinds of infrared film were available from five manufacturers including Agfa, Kodak and Ilford. Infrared movie film was also available and was used to create day-for-night effects in motion pictures, a notable example being the pseudo-night aerial sequences in the James Cagney/Bette Davis movie The Bride Came COD.
False-color infrared photography became widely practiced with the introduction of Kodak Ektachrome Infrared Aero Film and Ektachrome Infrared EIR. The first version of this, known as Kodacolor Aero-Reversal-Film, was developed by Clark and others at the Kodak for camouflage detection in the 1940s. The film became more widely available in 35mm form in the 1960s but KODAK AEROCHROME III Infrared Film 1443 has been discontinued.
Infrared photography became popular with a number of 1960s recording artists, because of the unusual results; Jimi Hendrix, Donovan, Frank and a slow shutter speed without focus compensation, however wider apertures like f/2.0 can produce sharp photos only if the lens is meticulously refocused to the infrared index mark, and only if this index mark is the correct one for the filter and film in use. However, it should be noted that diffraction effects inside a camera are greater at infrared wavelengths so that stopping down the lens too far may actually reduce sharpness.
Most apochromatic ('APO') lenses do not have an Infrared index mark and do not need to be refocused for the infrared spectrum because they are already optically corrected into the near-infrared spectrum. Catadioptric lenses do not often require this adjustment because their mirror containing elements do not suffer from chromatic aberration and so the overall aberration is comparably less. Catadioptric lenses do, of course, still contain lenses, and these lenses do still have a dispersive property.
Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film. The Kodak HIE film was sensitive to 900 nm.
As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved." At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.
Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the marketneeds update with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.
Color infrared transparency films have three sensitized layers that, because of the way the dyes are coupled to these layers, reproduce infrared as red, red as green, and green as blue. All three layers are sensitive to blue so the film must be used with a yellow filter, since this will block blue light but allow the remaining colors to reach the film. The health of foliage can be determined from the relative strengths of green and infrared light reflected; this shows in color infrared as a shift from red (healthy) towards magenta (unhealthy). Early color infrared films were developed in the older E-4 process, but Kodak later manufactured a color transparency film that could be developed in standard E-6 chemistry, although more accurate results were obtained by developing using the AR-5 process. In general, color infrared does not need to be refocused to the infrared index mark on the lens.
In 2007 Kodak announced that production of the 35 mm version of their color infrared film (Ektachrome Professional Infrared/EIR) would cease as there was insufficient demand. Since 2011, all formats of color infrared film have been discontinued. Specifically, Aerochrome 1443 and SO-734.
There is no currently available digital camera that will produce the same results as Kodak color infrared film although the equivalent images can be produced by taking two exposures, one infrared and the other full-color, and combining in post-production. The color images produced by digital still cameras using infrared-pass filters are not equivalent to those produced on color infrared film. The colors result from varying amounts of infrared passing through the color filters on the photo sites, further amended by the Bayer filtering. While this makes such images unsuitable for the kind of applications for which the film was used, such as remote sensing of plant health, the resulting color tonality has proved popular artistically.
Color digital infrared, as part of full spectrum photography is gaining popularity. The ease of creating a softly colored photo with infrared characteristics has found interest among hobbyists and professionals.
In 2008, Los Angeles photographer, Dean Bennici started cutting and hand rolling Aerochrome color Infrared film. All Aerochrome medium and large format which exists today came directly from his lab. The trend in infrared photography continues to gain momentum with the success of photographer Richard Mosse and multiple users all around the world.
Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras. Thus, to improve image quality and protect privacy, many digital cameras employ infrared blockers. Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.
An alternative method of DSLR infrared photography is to remove the infrared blocker in front of the sensor and replace it with a filter that removes visible light. This filter is behind the mirror, so the camera can be used normally - handheld, normal shutter speeds, normal composition through the viewfinder, and focus, all work like a normal camera. Metering works but is not always accurate because of the difference between visible and infrared refraction. When the IR blocker is removed, many lenses which did display a hotspot cease to do so, and become perfectly usable for infrared photography. Additionally, because the red, green and blue micro-filters remain and have transmissions not only in their respective color but also in the infrared, enhanced infrared color may be recorded.
Since the Bayer filters in most digital cameras absorb a significant fraction of the infrared light, these cameras are sometimes not very sensitive as infrared cameras and can sometimes produce false colors in the images. An alternative approach is to use a Foveon X3 sensor, which does not have absorptive filters on it; the Sigma SD10 DSLR has a removable IR blocking filter and dust protector, which can be simply omitted or replaced by a deep red or complete visible light blocking filter. The Sigma SD14 has an IR/UV blocking filter that can be removed/installed without tools. The result is a very sensitive digital IR camera.
While it is common to use a filter that blocks almost all visible light, the wavelength sensitivity of a digital camera without internal infrared blocking is such that a variety of artistic results can be obtained with more conventional filtration. For example, a very dark neutral density filter can be used (such as the Hoya ND400) which passes a very small amount of visible light compared to the near-infrared it allows through. Wider filtration permits an SLR viewfinder to be used and also passes more varied color information to the sensor without necessarily reducing the Wood effect. Wider filtration is however likely to reduce other infrared artefacts such as haze penetration and darkened skies. This technique mirrors the methods used by infrared film photographers where black-and-white infrared film was often used with a deep red filter rather than a visually opaque one.
Another common technique with near-infrared filters is to swap blue and red channels in software (e.g. photoshop) which retains much of the characteristic 'white foliage' while rendering skies a glorious blue.
Several Sony cameras had the so-called Night Shot facility, which physically moves the blocking filter away from the light path, which makes the cameras very sensitive to infrared light. Soon after its development, this facility was 'restricted' by Sony to make it difficult for people to take photos that saw through clothing. To do this the iris is opened fully and exposure duration is limited to long times of more than 1/30 second or so. It is possible to shoot infrared but neutral density filters must be used to reduce the camera's sensitivity and the long exposure times mean that care must be taken to avoid camera-shake artifacts.
Fuji have produced digital cameras for use in forensic criminology and medicine which have no infrared blocking filter. The first camera, designated the S3 PRO UVIR, also had extended ultraviolet sensitivity (digital sensors are usually less sensitive to UV than to IR). Optimum UV sensitivity requires special lenses, but ordinary lenses usually work well for IR. In 2007, FujiFilm introduced a new version of this camera, based on the Nikon D200/ FujiFilm S5 called the IS Pro, also able to take Nikon lenses. Fuji had earlier introduced a non-SLR infrared camera, the IS-1, a modified version of the FujiFilm FinePix S9100. Unlike the S3 PRO UVIR, the IS-1 does not offer UV sensitivity. FujiFilm restricts the sale of these cameras to professional users with their EULA specifically prohibiting "unethical photographic conduct".
Phase One digital camera backs can be ordered in an infrared modified form.
Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared (see Infrared spectrum#Commonly used sub-division scheme). They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera#Uncooled infrared detectors). These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well.
