Erfurt is the capital and largest city in the state of Thuringia, central Germany. It lies in the southern part of the Thuringian Basin, within the wide valley of the Gera river. It is located 100 km (62 mi) south-west of Leipzig, 300 km (186 mi) south-west of Berlin, 400 km (249 mi) north of Munich and 250 km (155 mi) north-east of Frankfurt. Together with neighbouring cities Weimar and Jena it forms the central metropolitan area of Thuringia with approximately 500,000 inhabitants.
Erfurt's old town is one of the most intact medieval cities in Germany having survived World War II with little damage. Tourist attractions include the Krämerbrücke (Merchants' bridge), the ensemble of Erfurt Cathedral and Severikirche (St Severus's Church) and Petersberg Citadel, one of the largest and best preserved town fortresses in Europe. The city's economy is based on agriculture, horticulture and microelectronics. Its central location has led to it becoming a logistics hub for Germany and central Europe. Erfurt hosts the second-largest trade fair in eastern Germany (after Leipzig) as well as the public television children’s channel KiKa.
At the west end of downtown Camas is a large Georgia-Pacific paper-mill from which the high school teams get their name "the Papermakers". Accordingly, the city is about 20 miles east (upwind) from Portland, Oregon. Historically, the commercial base of the city was almost solely the paper mill; however, the diversity of industries has been enhanced considerably in recent years by the influx of several white-collar, high-tech companies including Hewlett-Packard, Sharp Microelectronics, Linear Technology, WaferTech and Underwriters Labs.

This is an Erasable Programmable Read Only Memory (EPROM for short). Our computers in 1980's used to employ these chips to hold the BIOS. Nowadays we use FLASH chips. The thinnest electrical tracks on the chip must be 2 microns thick. You can see them if you view the photo in original size. Did you notice 2732 (the part number) in the upper right corner of the chip?
Sorry if you are not into electronics. In this photography group my aim is to demonstrate that one can capture such submillimeter features by using macro lenses. I used a 70 mm SIGMA macro lens. Of course a tripod, timed shutter to prevent camera shake and a LED light source are necessary for a successful shot.

A miniature vacuum tube (valve), popularized in the 1950s, next to the circuit board from a USB switch, an example of surface-mount technology using sophisticated integrated circuits, technologies introduced in the 1980s and continually refined since.
Each chip contains one million or more microscopic transistors, a small number of each roughly functionally comparable to what one tube did. Imagine replicating the function of this circuit using tubes, and you'll end up with something taking up a convention center's worth of space, consuming an astounding amount of power to run and cool, and basically being a reliability nightmare compared to what modern microelectronics can achieve nowadays.

This natural colour image from Sentinel-2A on 29 August features the area of Les Deux Alpes and surroundings, in France. A ski resort in the French Isère department, the village of Les Deux Alpes sits at 1650 m with its ski lifts running up to 3600 m.
Located near Western Europe’s largest mountain, Mont Blanc, it accesses the greatest skiable glacier in Europe and is France’s second oldest ski resort.
The relief differences in the area are clear thanks to Sentinel-2’s high-resolution multispectral instrument. The brownish colours represent those parts of the mountains without vegetation or settlements. The village of Le Bourg-d’Oisans is clearly visible in the centre of the image, with agricultural plots around it.
The grey area on the top left corner is the city of Grenoble, in the Rhône-Alps region of southeastern France. It sits along the Isère River, at 214 m above sea level.
Home to some 160 000 people, Grenoble’s history goes back 2000 years. Today it is a leading scientific research centre, renowned for research in nuclear physics and microelectronics.
Among various bodies of water, the Lac Monteynard-Avignonet is clearly visible, snaking its way down the image. This is a 10 km-long and, in some places, 300 m-wide artificial reservoir created in 1961. Often windy and rippled, the lake is considered to be one of the best places for wind and kite surfing in Europe.
Sentinel-2A has been in orbit since 23 June as a polar-orbiting, high-resolution satellite for land monitoring, providing imagery of vegetation, soil and water cover, inland waterways and coastal areas.

Do you still use a film camera? How about a point and shoot camera? What about a DSLR? Technology is quickly changing; here is a picture of what the future holds:
The Internet of Bio-Nano Things will bridge the gap between microelectronics and biological systems; it will transform the systems of our bodies into smart devices. The free flow of data between electronic and biological worlds will represent a completely new paradigm shift, a shift to transhumanism.
In our biological systems, we have redox molecules that are capable of transferring electrons. Imagine all the data we will tap into and control. We will use a microbial network, plugged into an external electronic system, so that we’ll be able to control biological functions in real time. We will use an electronic system along with engineered microbial cells to create an electronically controlled biological network called the 666 BioLAN.
If you’re not a computer nerd, LAN means: Local Area Network. It consists of a series of computers and smart devices, which are connected together to form a network in a local location. Similarly, the 666 BioLAN will use a network of engineered cells, which will convert data delivered through an electronic input, thus stimulating a biological response. In turn, this biological response will transmit data across a microbial network, so that it can carry out network functions.
The Living Electrode is a special component of this system. It was created by binding engineered cells to the surface of a gold electrode. This Living Electrode facilitates a redox reaction, which is needed to translate electronic signals into data, so that it can be read by a biological system.
It’s a hybrid system that combines electronics and biology. It’s digitally programmed, but biologically executed. In electrogenetics we use electronic signals to activate gene expression, so that we can enable data transfer from electronics to biology and back. We will use electronics to control biological processes.
This process has already begun. We have introduced new gene editing technologies into the Covid-19 vaccines. We are also introducing these same gene editing technologies into the animal and plant populations. Our goal is to edit all life on earth, so that we can patent and control it. We use Spike Proteins to weaken the immune system, so that Graphene Oxide nano-particles can enter the cells of the body. We are using Graphene to slowly build nano-networks and nano-antennas inside the human body.
We will soon introduce a Social Credit Score System so that, in order to participate in society (buy food and pay rent), the population will have to comply with the latest vaccine mandates. In a few years, when these Graphene Networks are fully complete, each person will receive the mandatory Pentium 6.66 GHz Chip. Once people are microchipped with this Beast Chip, they will no longer be human, they will be transhuman. We will take neuromorphic computing to the next level. We will use technology to evolve into gods. Take the Mark, worship the Beast. Humans are now obsolete!
Matthew 24:12-13 “Because of the increase of wickedness, the love of most will grow cold, but the one who stands firm to the end will be saved.”

Multiple integrated circuits destined to serve as the brains of Europe’s future space missions, etched together onto single pieces of silicon.
These 20-cm diameter wafers each contain 35 replicas of five different space chips, each incorporating as many as 10 million transistors or basic circuit switches.
Laid down within a microchip, these designs endow a space mission with the ability to perform various specialised tasks such as data handling, communications processing or attitude control.
To save money on the high cost of fabrication, various chips designed by different companies and destined for multiple ESA projects are crammed onto the same silicon wafers, etched into place at specialised semiconductor manufacturing plants.
Subjected to various testing procedures the chips on the wafer are chopped up and packaged for use, then mounted on printed circuit boards for connection with other microelectronic components aboard a satellite. Visitors to ESA’s ESTEC technical centre can see some of these silicon wafers exhibited along the establishment’s main corridor.
Since 2002, ESA’s Microelectronics section has maintained a catalogue of ‘building blocks’ for chip designs, known as intellectual property cores, available to European industry through ESA licence. For more information, check this recently updated overview of which ESA IP cores are available and how they can be requested and licenced.

This historical chip is tagged twice: "copyright Intel 1974" and
"2708", the latter indicates an EPROM (memory chip) with 1K byte (!). This was very High Tech, 50 years ago! You would need around 2000+ such chips, to store ONE simple jpeg picture of today's cameras.
The curcuit has a (quartz-) glass window, which allows to erase the bits stored, using UV light. The picture shown here has been shot through this window (thus image quality is less than optimal).

A close-up of the next-generation microprocessor that will serve a wide variety of future space missions.
Standard terrestrial chips wouldn’t last very long in orbit under the harsh blast of space radiation. So ESA has had a long history of working with industry on specially ‘rad-hardened’ designs for space.
This GR740 microprocessor, developed by Cobham Gaisler in Sweden and manufactured by France-based STMicroelectronics, is a quadcore design combining four embedded LEON4 cores. The LEON4 is the latest member of a series of chips that began with the LEON2-FT, developed at ESA from the second half of the 1990s.
For more information on the device and ESA’s role in microprocessor development, watch our video interview with ESA microelectronics engineer Roland Weigand.

This tiny fingernail-length space thruster chip runs on the greenest propellant of all: water.
Designed to manoeuvre the smallest classes of satellite, the operation of this Iridium Catalysed Electrolysis CubeSat Thruster (ICE-Cube Thruster) developed with Imperial College in the UK is based on electrolysis.
Avoiding any need for bulky gaseous propellant storage, an associated electrolyser runs a 20-watt current through water to produce hydrogen and oxygen to propel the thruster.
The ICE-Cube Thruster is so small in scale – with its combustion chamber and nozzle measuring less than 1mm in length – that it could only be assembled using a MEMS (Micro-Electrical Mechanical Systems) approach, borrowing methods from the microelectronics sector.
A test campaign achieved 1.25 millinewtons of thrust at a specific impulse of 185 seconds on a sustained basis. Testing took place through an ESA General Support Technology Programme De-Risk activity, to prove the thruster’s feasibility in a laboratory testing.
The experimental data gathered during this activity will help guide development of a flight-representative ‘Engineering Model’ of the propulsion system, including the electrolyser.

This is one of my all-time favorite images of one of my all-time favorite interlocking towers. This is a scene of the 1908-vintage Improved Saxby & Farmer interlocking machine. The location is Chicago's 75th Street Tower, where the participants were the Baltimore & Ohio Chicago Terminal (B&OCT), Pennsylvania (Panhandle), Belt Railway of Chicago (BRC) and Wabash.
Over the last three or four years of the tower's existence, I struck up a friendship with a few of the operators who worked there. Through their "open door policy", I got to experience the wonders of a nearly fully-mechanical interlocking plant in the final years of the 20th century. I got to pull levers and found that they did indeed require strong arms. I'll remember hearing the pipeline leadout set in motion below the floor with the motion of my hands on the lever, and remember watching out the window and seeing the semaphore blade rise skyward with the movement of the lever gripped by my hands.
Along with the opportunity to experience this mechanical marvel that lived long beyond its years, the "open door policy" granted me by the railroaders of 75th Street Tower allowed me to make a comprehensive photographic documentation of the tower and the outside plant. I spent evenings on the operating floor and downstairs in the locking room with my camera, tripod, and lights trying to capture this tower before technology caught up with it.
My visits became more and more frequent in 1997 as it became clear that 75th Street's days were numbered. This anachronism had been long on the list to be replaced, but the impetus for its closure wound up being Union Pacific's desire for its trains to travel between its ex-MoPac yard in the south suburbs and Proviso Yard on UP's recently-acquired ex-C&NW lines. This new routing via the Belt and B&OCT required a new connection in the northeast quadrant of the 75th Street plant, and was the final "straw that broke the camel's back" that precipitated the long-deferred closing of the tower.
This image was taken on November 14, 1997, just two weeks before the transition from 19th century mechanical interlocking to modern microelectronics. The sand finally ran out of 75th Street Tower's hourglass with the plant being taken out of service on Friday, November 28, 1997. The cutover took the balance of Thanksgiving weekend. When the last operator went home and locked the tower door on Sunday afternoon, November 30, 1997, an era had truly come to an end.
Arati Prabhakar has always been drawn to the edge of the known. From her early years as an electrical engineer to her tenure at the helm of DARPA, she has spent a lifetime navigating the liminal space where science meets bold ambition. When I photographed her at her gracious home on May 9, 2022, I found a setting that mirrored her intellectual curiosity: a telescope perched on the deck, aimed at the vast unknown.
Born in India and raised in Texas, Prabhakar was the first woman to earn a PhD in applied physics from Caltech. But her journey was never one of mere academic pursuit—she was an engineer with the soul of an explorer. She cut her teeth at DARPA in the 1980s, returned decades later to lead it, and brought that same daring spirit to Silicon Valley, where she shaped the trajectory of emerging technologies.
At the time of our conversation, she had been tapped to lead the White House Office of Science and Technology Policy (OSTP), a role that would place her at the intersection of science and governance, helping shape the nation’s response to the defining challenges of the era—pandemic preparedness, climate resilience, artificial intelligence, and the stewardship of emerging technologies. Over tea, she spoke about DARPA’s approach—how it thrived on risk, demanding visionary thinking rather than incremental advances. She recounted her work fostering innovations in AI, microelectronics, and bioengineering, not as a detached observer, but as a true believer in the power of technology to reshape the world.
Our conversation drifted between policy, physics, and the delicate art of steering a country’s research agenda. At the heart of it all was a scientist who understood both the beauty and burden of responsibility that comes with wielding technological power. In that moment, framed by the quiet of her home, she was not just a scientist or a policymaker—she was a navigator of the future, peering through the lens of discovery, always searching for what comes next.
ELSA (Italy) RFID access control tag using a GM Hughes Microelectronics (Scotland) H223 chip. Hughes were an early RFID innovator, with chip design in Scotland and the US, tag manufacturing in Spain and a separate Hughes Identification Devices business in the US (which became the company HID). HID is still very widely used for access control.
The above was an early tag. It wasn't before 2000 that I had an access control card for work, similar to the HID one in the link at the bottom.

Tiny integrated circuits destined for space missions, etched onto a single wafer of silicon, examined under a magnifier.
To save money on the high cost of fabrication, various chips designed by different companies and destined for multiple ESA projects are crammed onto the same silicon wafers, etched into place at specialised semiconductor manufacturing plants or ‘fabs’.
Once manufactured, the chips, still on the wafer, are tested. The wafers are then chopped up. They become ready for use when placed inside protective packages – just like standard terrestrial microprocessors – and undergo final quality tests.
Through little metal pins or balls sticking out of their packages these miniature brains are then connected to other circuit elements – such as sensors, actuators, memory or power systems – used across the satellite.
Considering the time and money needed to develop complex chips like these, ESA’s Microelectronics section maintains a catalogue of chip designs, known as Intellectual Property (IP) cores, available to European industry through ESA licence.
Think of these IP cores as the tiniest mission ‘building blocks’: specialised designs to perform particular tasks in space, laid down within a microchip. These range from single ‘simpler’ functions such as decoding signals from Earth to control the satellite to highly complex computer tasks such as operating a complete spacecraft.

Dennis Trident / Plaxton President number 640 (SK52 OGY) leaves Riccarton,
the leafy campus of Heriot Watt University.
When I'm waiting for buses to photograph here I sometimes feel a little
self-conscious as everyone I see coming and going from the various buildings
is some twenty years (at least) younger than me! Ah well never mind I hope
they all do well to get their degrees while I can carry on doing my little bit
of historic research too!
The Riccarton estate was the historic home of the Gibson-Craig family and
strong reminders of the family's love of trees, plants and landscaping
remain. The sleek low rise buildings are surrounded by mature woods and
playing fields, and at their centre is a striking loch. To one side lies the
expanding Research Park, which makes industry a part of campus life, indeed
Heriot-Watt has always had a strong business focus.
The Riccarton Campus houses petroleum and offshore engineering research, the
Scotch Whisky Research Institute, and the newly founded National
Microelectronics Institute (NMI), all of special significance for the
Scottish economy.

States with the highest proportions of German Americans tend to be those of the upper Midwest, including Iowa, Minnesota, Nebraska, Wisconsin, and the Dakotas; all at over one-third.
German Americans (German: Deutschamerikaner) are Americans who have full or partial German ancestry.
With an estimated size of approximately 44 million in 2016, German Americans are the largest of the self-reported ancestry groups by the US Census Bureau in its American Community Survey.
In the 1990 U.S. Census, 58 million Americans claimed to be solely or partially of German descent.
German-Americans account for about one third of the total ethnic German population in the world.
German Americans established the first kindergartens in the United States, introduced the Christmas tree tradition, and introduced popular foods such as hot dogs and hamburgers to America.
The great majority of people with some German ancestry have become Americanized and can hardly be distinguished by the untrained eye; fewer than 5% speak German.

The influence of German cuisine is seen in the cuisine of the United States throughout the country, especially regarding pastries, meats and sausages, and above all, beer. Frankfurters (or "wieners", originating from Frankfurt am Main and Vienna, respectively), hamburgers, bratwurst, sauerkraut, and strudel are common dishes.
German bakers introduced the pretzel, which is popular across the United States.
Germans introduced America to lager, the most-produced beer style in the United States, and have been the dominant ethnic group in the beer industry since 1850.
The oldest extant brewery in the United States is D. G. Yuengling & Son of Pottsville, Pennsylvania (approximately 80 miles northwest of Philadelphia), founded in 1829 by an immigrant from Aldingen (near Tuttlingen) in what is today Baden-Württemberg;
the brewery's flagship product remains a 19th-century German-style amber lager.
By the late 19th century, Milwaukee, with a large population of German origin, was once the home to four of the world's largest breweries owned by ethnic Germans (Schlitz, Blatz, Pabst, and Miller) and was the number one beer producing city in the world for many years.
Almost half of all current beer sales in the United States can be attributed to German immigrants, Capt. A. Pabst, Eberhard Anheuser, and Adolphus Busch, who founded Anheuser-Busch in St. Louis in 1860.
Later German immigrants figured prominently in the rebirth of craft brews following Prohibition, culminating in the microbrew movement that swept the U.S. beginning in the late 1980s.

The Old Town Hall is a municipal building in West Street, Gateshead, England.
History
The first town hall in Gateshead was in Bush Yard. The council subsequently established itself in a building in Greenesfield in 1844. The foundation stone for the current building was laid in 1868: a stand collapsed during the ceremony killing a member of the public. The current building was designed in the Italianate style by John Johnstone who had also designed Newcastle Town Hall. Construction work on the Gateshead building was delayed after preparatory work penetrated a coal seam leading to the collapse of nearby properties and the building was eventually completed in 1870. The design involved a symmetrical main frontage with seven bays facing onto West Street; the central section of three bays, which slightly projected forward, featured a round headed doorway on the ground floor, and three stained glass windows on the first floor: there was an ornately carved pediment with a statue depicting justice at roof level.
The old town hall also served as a magistrates' court and a police station. In 1892 an ornamental clock (By Gillett & Johnston), which is Grade II listed and stands in front of the town hall, was presented to Gateshead by the mayor, Walter de Lancey Willson, on the occasion of him being elected for a third time. He was also one of the founders of Walter Willson's, a chain of grocers in the North East and Cumbria. Queen Elizabeth II, accompanied by the Duke of Edinburgh, crossed the Tyne Bridge from the north and signed the town hall visitors' book at a small table on the south side of the bridge on 29 October 1954.
The building remained the headquarters of the Metropolitan Borough of Gateshead until the council moved to Gateshead Civic Centre in Regent Street in 1987. The town hall was occupied by the Microelectronics Applications Research Institute ('MARI') who established their head office in the building from 1987 to 2001. It was then briefly used by the management of Sage Gateshead while they waited for their new building at Gateshead Quays to be competed in December 2004.
The Tyneside Cinema occupied the town hall under a short term lease while a restoration and renovation project was undertaken on their premises in Newcastle upon Tyne between November 2006 and May 2008. The main performance hall in the old town hall was refurbished in 2009 and the building was managed by Sage Gateshead from January 2013. In 2018 it was acquired by "Dinosauria" which has announced plans to convert it into an "unnatural history museum".
Gateshead is a town in the Gateshead Metropolitan Borough of Tyne and Wear, England. It is on the River Tyne's southern bank. The town's attractions include the twenty metre tall Angel of the North sculpture on the town's southern outskirts, The Glasshouse International Centre for Music and the Baltic Centre for Contemporary Art. The town shares the Millennium Bridge, Tyne Bridge and multiple other bridges with Newcastle upon Tyne.
Historically part of County Durham, under the Local Government Act 1888 the town was made a county borough, meaning it was administered independently of the county council.
In the 2011 Census, the town had a population of 120,046 while the wider borough had 200,214.
History
Gateshead is first mentioned in Latin translation in Bede's Ecclesiastical History of the English People as ad caput caprae ("at the goat's head"). This interpretation is consistent with the later English attestations of the name, among them Gatesheued (c. 1190), literally "goat's head" but in the context of a place-name meaning 'headland or hill frequented by (wild) goats'. Although other derivations have been mooted, it is this that is given by the standard authorities.
A Brittonic predecessor, named with the element *gabro-, 'goat' (c.f. Welsh gafr), may underlie the name. Gateshead might have been the Roman-British fort of Gabrosentum.
Early
There has been a settlement on the Gateshead side of the River Tyne, around the old river crossing where the Swing Bridge now stands, since Roman times.
The first recorded mention of Gateshead is in the writings of the Venerable Bede who referred to an Abbot of Gateshead called Utta in 623. In 1068 William the Conqueror defeated the forces of Edgar the Ætheling and Malcolm king of Scotland (Shakespeare's Malcolm) on Gateshead Fell (now Low Fell and Sheriff Hill).
During medieval times Gateshead was under the jurisdiction of the Bishop of Durham. At this time the area was largely forest with some agricultural land. The forest was the subject of Gateshead's first charter, granted in the 12th century by Hugh du Puiset, Bishop of Durham. An alternative spelling may be "Gatishevede", as seen in a legal record, dated 1430.
Industrial revolution
Throughout the Industrial Revolution the population of Gateshead expanded rapidly; between 1801 and 1901 the increase was over 100,000. This expansion resulted in the spread southwards of the town.
In 1854, a catastrophic explosion on the quayside destroyed most of Gateshead's medieval heritage, and caused widespread damage on the Newcastle side of the river.
Sir Joseph Swan lived at Underhill, Low Fell, Gateshead from 1869 to 1883, where his experiments led to the invention of the electric light bulb. The house was the first in the world to be wired for domestic electric light.
In the 1889 one of the largest employers (Hawks, Crawshay and Company) closed down and unemployment has since been a burden. Up to the Second World War there were repeated newspaper reports of the unemployed sending deputations to the council to provide work. The depression years of the 1920s and 1930s created even more joblessness and the Team Valley Trading Estate was built in the mid-1930s to alleviate the situation.
Regeneration
In the late noughties, Gateshead Council started to regenerate the town, with the long-term aim of making Gateshead a city. The most extensive transformation occurred in the Quayside, with almost all the structures there being constructed or refurbished in this time.
In the early 2010s, regeneration refocused on the town centre. The £150 million Trinity Square development opened in May 2013, it incorporates student accommodation, a cinema, health centre and shops. It was nominated for the Carbuncle Cup in September 2014. The cup was however awarded to another development which involved Tesco, Woolwich Central.
Governance
In 1835, Gateshead was established as a municipal borough and in 1889 it was made a county borough, independent from Durham County Council.
In 1870, the Old Town Hall was built, designed by John Johnstone who also designed the previously built Newcastle Town Hall. The ornamental clock in front of the old town hall was presented to Gateshead in 1892 by the mayor, Walter de Lancey Willson, on the occasion of him being elected for a third time. He was also one of the founders of Walter Willson's, a chain of grocers in the North East and Cumbria. The old town hall also served as a magistrate's court and one of Gateshead's police stations.
Current
In 1974, following the Local Government Act 1972, the County Borough of Gateshead was merged with the urban districts of Felling, Whickham, Blaydon and Ryton and part of the rural district of Chester-le-Street to create the much larger Metropolitan Borough of Gateshead.
Geography
The town of Gateshead is in the North East of England in the ceremonial county of Tyne and Wear, and within the historic boundaries of County Durham. It is located on the southern bank of the River Tyne at a latitude of 54.57° N and a longitude of 1.35° W. Gateshead experiences a temperate climate which is considerably warmer than some other locations at similar latitudes as a result of the warming influence of the Gulf Stream (via the North Atlantic drift). It is located in the rain shadow of the North Pennines and is therefore in one of the driest regions of the United Kingdom.
One of the most distinguishing features of Gateshead is its topography. The land rises 230 feet from Gateshead Quays to the town centre and continues rising to a height of 525 feet at Queen Elizabeth Hospital in Sheriff Hill. This is in contrast to the flat and low lying Team Valley located on the western edges of town. The high elevations allow for impressive views over the Tyne valley into Newcastle and across Tyneside to Sunderland and the North Sea from lookouts in Windmill Hills and Windy Nook respectively.
The Office for National Statistics defines the town as an urban sub-division. The latest (2011) ONS urban sub-division of Gateshead contains the historical County Borough together with areas that the town has absorbed, including Dunston, Felling, Heworth, Pelaw and Bill Quay.
Given the proximity of Gateshead to Newcastle, just south of the River Tyne from the city centre, it is sometimes incorrectly referred to as being a part of Newcastle. Gateshead Council and Newcastle City Council teamed up in 2000 to create a unified marketing brand name, NewcastleGateshead, to better promote the whole of the Tyneside conurbation.
Economy
Gateshead is home to the MetroCentre, the largest shopping mall in the UK until 2008; and the Team Valley Trading Estate, once the largest and still one of the larger purpose-built commercial estates in the UK.
Arts
The Baltic Centre for Contemporary Art has been established in a converted flour mill. The Glasshouse International Centre for Music, previously The Sage, a Norman Foster-designed venue for music and the performing arts opened on 17 December 2004. Gateshead also hosted the Gateshead Garden Festival in 1990, rejuvenating 200 acres (0.81 km2) of derelict land (now mostly replaced with housing). The Angel of the North, a famous sculpture in nearby Lamesley, is visible from the A1 to the south of Gateshead, as well as from the East Coast Main Line. Other public art include works by Richard Deacon, Colin Rose, Sally Matthews, Andy Goldsworthy, Gordon Young and Michael Winstone.
Traditional and former
The earliest recorded coal mining in the Gateshead area is dated to 1344. As trade on the Tyne prospered there were several attempts by the burghers of Newcastle to annex Gateshead. In 1576 a small group of Newcastle merchants acquired the 'Grand Lease' of the manors of Gateshead and Whickham. In the hundred years from 1574 coal shipments from Newcastle increased elevenfold while the population of Gateshead doubled to approximately 5,500. However, the lease and the abundant coal supplies ended in 1680. The pits were shallow as problems of ventilation and flooding defeated attempts to mine coal from the deeper seams.
'William Cotesworth (1668-1726) was a prominent merchant based in Gateshead, where he was a leader in coal and international trade. Cotesworth began as the son of a yeoman and apprentice to a tallow - candler. He ended as an esquire, having been mayor, Justice of the Peace and sheriff of Northumberland. He collected tallow from all over England and sold it across the globe. He imported dyes from the Indies, as well as flax, wine, and grain. He sold tea, sugar, chocolate, and tobacco. He operated the largest coal mines in the area, and was a leading salt producer. As the government's principal agent in the North country, he was in contact with leading ministers.
William Hawks originally a blacksmith, started business in Gateshead in 1747, working with the iron brought to the Tyne as ballast by the Tyne colliers. Hawks and Co. eventually became one of the biggest iron businesses in the North, producing anchors, chains and so on to meet a growing demand. There was keen contemporary rivalry between 'Hawks' Blacks' and 'Crowley's Crew'. The famous 'Hawks' men' including Ned White, went on to be celebrated in Geordie song and story.
In 1831 a locomotive works was established by the Newcastle and Darlington Railway, later part of the York, Newcastle and Berwick Railway. In 1854 the works moved to the Greenesfield site and became the manufacturing headquarters of North Eastern Railway. In 1909, locomotive construction was moved to Darlington and the rest of the works were closed in 1932.
Robert Stirling Newall took out a patent on the manufacture of wire ropes in 1840 and in partnership with Messrs. Liddell and Gordon, set up his headquarters at Gateshead. A worldwide industry of wire-drawing resulted. The submarine telegraph cable received its definitive form through Newall's initiative, involving the use of gutta-percha surrounded by strong wires. The first successful Dover–Calais cable on 25 September 1851, was made in Newall's works. In 1853, he invented the brake-drum and cone for laying cable in deep seas. Half of the first Atlantic cable was manufactured in Gateshead. Newall was interested in astronomy, and his giant 25-inch (640 mm) telescope was set up in the garden at Ferndene, his Gateshead residence, in 1871.
Architecture
JB Priestley, writing of Gateshead in his 1934 travelogue English Journey, said that "no true civilisation could have produced such a town", adding that it appeared to have been designed "by an enemy of the human race".
Victorian
William Wailes the celebrated stained-glass maker, lived at South Dene from 1853 to 1860. In 1860, he designed Saltwell Towers as a fairy-tale palace for himself. It is an imposing Victorian mansion in its own park with a romantic skyline of turrets and battlements. It was originally furnished sumptuously by Gerrard Robinson. Some of the panelling installed by Robinson was later moved to the Shipley Art gallery. Wailes sold Saltwell Towers to the corporation in 1876 for use as a public park, provided he could use the house for the rest of his life. For many years the structure was essentially an empty shell but following a restoration programme it was reopened to the public in 2004.
Post millennium
The council sponsored the development of a Gateshead Quays cultural quarter. The development includes the Gateshead Millennium Bridge, erected in 2001, which won the prestigious Stirling Prize for Architecture in 2002.
Former brutalism
The brutalist Trinity Centre Car Park, which was designed by Owen Luder, dominated the town centre for many years until its demolition in 2010. A product of attempts to regenerate the area in the 1960s, the car park gained an iconic status due to its appearance in the 1971 film Get Carter, starring Michael Caine. An unsuccessful campaign to have the structure listed was backed by Sylvester Stallone, who played the main role in the 2000 remake of the film. The car park was scheduled for demolition in 2009, but this was delayed as a result of a disagreement between Tesco, who re-developed the site, and Gateshead Council. The council had not been given firm assurances that Tesco would build the previously envisioned town centre development which was to include a Tesco mega-store as well as shops, restaurants, cafes, bars, offices and student accommodation. The council effectively used the car park as a bargaining tool to ensure that the company adhered to the original proposals and blocked its demolition until they submitted a suitable planning application. Demolition finally took place in July–August 2010.
The Derwent Tower, another well known example of brutalist architecture, was also designed by Owen Luder and stood in the neighbourhood of Dunston. Like the Trinity Car Park it also failed in its bid to become a listed building and was demolished in 2012. Also located in this area are the Grade II listed Dunston Staithes which were built in 1890. Following the award of a Heritage Lottery Fund grant of almost £420,000 restoration of the structure is expected to begin in April 2014.
Sport
Gateshead International Stadium regularly holds international athletics meetings over the summer months, and is home of the Gateshead Harriers athletics club. It is also host to rugby league fixtures, and the home ground of Gateshead Football Club. Gateshead Thunder Rugby League Football Club played at Gateshead International Stadium until its purchase by Newcastle Rugby Limited and the subsequent rebranding as Newcastle Thunder. Both clubs have had their problems: Gateshead A.F.C. were controversially voted out of the Football League in 1960 in favour of Peterborough United, whilst Gateshead Thunder lost their place in Super League as a result of a takeover (officially termed a merger) by Hull F.C. Both Gateshead clubs continue to ply their trade at lower levels in their respective sports, thanks mainly to the efforts of their supporters. The Gateshead Senators American Football team also use the International Stadium, as well as this it was used in the 2006 Northern Conference champions in the British American Football League.
Gateshead Leisure Centre is home to the Gateshead Phoenix Basketball Team. The team currently plays in EBL League Division 4. Home games are usually on a Sunday afternoon during the season, which runs from September to March. The team was formed in 2013 and ended their initial season well placed to progress after defeating local rivals Newcastle Eagles II and promotion chasing Kingston Panthers.
In Low Fell there is a cricket club and a rugby club adjacent to each other on Eastwood Gardens. These are Gateshead Fell Cricket Club and Gateshead Rugby Club. Gateshead Rugby Club was formed in 1998 following the merger of Gateshead Fell Rugby Club and North Durham Rugby Club.
Transport
Gateshead is served by the following rail transport stations with some being operated by National Rail and some being Tyne & Wear Metro stations: Dunston, Felling, Gateshead Interchange, Gateshead Stadium, Heworth Interchange, MetroCentre and Pelaw.
Tyne & Wear Metro stations at Gateshead Interchange and Gateshead Stadium provide direct light-rail access to Newcastle Central, Newcastle Airport , Sunderland, Tynemouth and South Shields Interchange.
National Rail services are provided by Northern at Dunston and MetroCentre stations. The East Coast Main Line, which runs from London Kings Cross to Edinburgh Waverley, cuts directly through the town on its way between Newcastle Central and Chester-le-Street stations. There are presently no stations on this line within Gateshead, as Low Fell, Bensham and Gateshead West stations were closed in 1952, 1954 and 1965 respectively.
Road
Several major road links pass through Gateshead, including the A1 which links London to Edinburgh and the A184 which connects the town to Sunderland.
Gateshead Interchange is the busiest bus station in Tyne & Wear and was used by 3.9 million bus passengers in 2008.
Cycle routes
Various bicycle trails traverse the town; most notably is the recreational Keelmans Way (National Cycle Route 14), which is located on the south bank of the Tyne and takes riders along the entire Gateshead foreshore. Other prominent routes include the East Gateshead Cycleway, which connects to Felling, the West Gateshead Cycleway, which links the town centre to Dunston and the MetroCentre, and routes along both the old and new Durham roads, which take cyclists to Birtley, Wrekenton and the Angel of the North.
Religion
Christianity has been present in the town since at least the 7th century, when Bede mentioned a monastery in Gateshead. A church in the town was burned down in 1080 with the Bishop of Durham inside.[citation needed] St Mary's Church was built near to the site of that building, and was the only church in the town until the 1820s. Undoubtedly the oldest building on the Quayside, St Mary's has now re-opened to the public as the town's first heritage centre.
Many of the Anglican churches in the town date from the 19th century, when the population of the town grew dramatically and expanded into new areas. The town presently has a number of notable and large churches of many denominations.
Judaism
The Bensham district is home to a community of hundreds of Jewish families and used to be known as "Little Jerusalem". Within the community is the Gateshead Yeshiva, founded in 1929, and other Jewish educational institutions with international enrolments. These include two seminaries: Beis Medrash L'Morot and Beis Chaya Rochel seminary, colloquially known together as Gateshead "old" and "new" seminaries.
Many yeshivot and kollels also are active. Yeshivat Beer Hatorah, Sunderland Yeshiva, Nesivos Hatorah, Nezer Hatorah and Yeshiva Ketana make up some of the list.
Islam
Islam is practised by a large community of people in Gateshead and there are 2 mosques located in the Bensham area (in Ely Street and Villa Place).
Twinning
Gateshead is twinned with the town of Saint-Étienne-du-Rouvray near Rouen in France, and the city of Komatsu in Japan.

Taken with a Sony A77 using an 18-200mm (at 200mm) plus a reversed 50mm lens to produce this extreme macro.
Magnification factor is about 3.35x. This was just a test shot to see how well the reversed and stacked 50mm would work for macro, but it came out looking nice enough to post. Focusing was just by making minute adjustments to the tripod legs, depth of field is negligible.. must get a macro focusing rail..

[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]
Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project
-------------------------------------------------- -------------
Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.
Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.
1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.
Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant
High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.
Nuclear-powered spaceship for Use of nuclear power are three kinds:
The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.
The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,
Plasma Engine
Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "
The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.
Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.
Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.
3, high-performance nuclear rocket
Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.
Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works.
Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust.
A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.
Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction.
Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.
Of course there are various research and development of rocket technology and technical solutions to try.
It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.
Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future _-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

2. radiation. Space radiation is one of the greatest threats to the safety of the astronauts, including X-rays, γ-rays, cosmic rays and high-speed solar particles. Better than aluminum protective effect of high polymer composite materials.
3. Air. Perhaps the oxygen needed to rely on oxidation-reduction reaction of hydrogen and ilmenite production of water, followed by water electrolysis to generate oxygen. Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.
4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.
Plantar molt
After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space
Bone and muscle loss
Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.
Space Blindness
Space Blindness refers astronaut decreased vision.
Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.
Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.
Osteoporosis and its complications ranked first in the space of disease risk.
Long-term health risks associated with flying Topics
The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.
Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.
Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections
Radiation hazards and protection
1) radiation medicine, biology and pathway effects Features
Radiation protection for interplanetary flight, since the lack of protective effect of Earth's magnetic field, and by the irradiation time is longer, the possibility of increased radiation hazard.
Analysis of space flight medical problems that may occur, loss of appetite topped the list, sleep disorders, fatigue and insomnia, in addition, space sickness, musculoskeletal system problems, eye problems, infections problems, skin problems and cardiovascular problems
---------------------------------------------------------
Development of diagnostic techniques in orbit, the development of the volume of power consumption, features a wide range of diagnostic techniques, such as applied research of ultrasound diagnostic techniques in the abdominal thoracic trauma, bone, ligament damage, dental / sinus infections and other complications and integrated;
Actively explore in orbit disposal of medical technology, weightlessness surgical methods, development of special surgical instruments, the role of narcotic drugs and the like.
——————————————————————————————-
However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding
With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.
Space sickness
In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.
Robot surgeons
Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.
Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.
Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.
These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.
In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.
Fuel storage
In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.
This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.
Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.
When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards
Mars
Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.
Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.
Super rigid parachute to help slow the landing vehicle.
Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very
Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.
In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.
The moon is sterile. Mars is another case entirely.
With dust treatment measures.
Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.
Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.
Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.
Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crust
The outermost layer of the crust.
Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.
Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.
In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.
Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core
The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].
Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Lunar surface relative content of each element (% by weight)
Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.
Lunar landscape
Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.
Regolith
TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.
Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology
Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project
[
"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.
In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.
In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.
Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.
Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.
.
After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.
Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.
The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.
Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.
Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.
Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.
Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown
Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.
Water quality monitoring sampling system:
Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.
Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.
Equipment cooling water system:
Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.
Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.
Safety Injection System: The main components of this system is the high-pressure injection pump.
Radioactive waste treatment systems:
Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.
Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.
