Built in 1929, this 17-story Art Deco-style former passenger railroad station was designed by Fellheimer & Wagner to replace the multiple previous train stations and termini in Buffalo, which were scattered throughout the city and belonged to different railroads. The structure stands on the site of the old Union Depot built in 1874, which closed in the early 1920s. The station began construction in 1925 when the New York Central Railroad settled on building their new union terminal in Buffalo at the site, with the station being built to accommodate the expected growth of Buffalo from a city of about 550,000 people to one with 1.5 million people, and to accommodate continued growth in passenger numbers. However, both of these projections never materialized, with the city’s population growth and the railroad’s passenger numbers growth, already slowing in the 1920s, slowing further due to the Great Depression during the 1930s, and then beginning a long, steady decline, only being briefly buoyed by World War II before falling out of favor as automobile travel proved more flexible and air travel more swift than train travel. Due to these circumstances, the terminal was overbuilt and never reached its full capacity during its operations, only coming close during World War II due to resource shortages and mass mobilization of the United States during wartime. The terminal was offered for sale by the New York Central Railroad for one million dollars in 1956, but found no buyers, with continuing declines in passenger numbers, coupled with the decline in the population of Buffalo itself, leading to several services being ended during the 1950s and 1960s. In 1966, the railroad, in an effort to save costs and downsize their facilities, demolished several outbuildings in the complex, and in 1968, the once powerful New York Central Railroad, a husk of its former self, merged with the Pennsylvania Railroad in an attempt to consolidate their expenses and save both companies, but this merger proved unsuccessful, leading to their bankruptcy in 1976, with both railroads absorbed into the public-private partnership known as Conrail.
In the meantime, Amtrak was formed in 1971 to provide passenger rail service in the United States, operating out of the terminal until 1979, with the agency facing budgetary limitations that did not allow them to renovate the aging structure, which, when coupled with the massive expenses of keeping the building comfortable, dry, and well-lit, led to the agency building two smaller stations in Buffalo during the 1970s to replace it. The terminal was subsequently purchased by Anthony T. Fedele, whom managed to maintain the building in decent condition, but was unable to find any interested developers to reuse the building, and eventually fell behind on taxes, leading to the building being seized at foreclosure so the taxes could be recouped by the government. During the time it was owned by Fedele, the building was vacated by Conrail’s offices between 1980 and 1984, and was listed on the National Register of Historic Places in 1984, with the final operations at the terminal, the interlocking towers that once signaled trains arriving at the station, being shut down in 1985. In 1986, the building was purchased at auction by Thomas Telesco, whom did not maintain the building, selling off many artifacts and fixtures from its interior, and proposing grandiose and unrealistic schemes of what he would do with the building, including being a stop on a high-speed rail line between New York and Toronto. The building was then sold to Bernie Tuchman and Samuel Tuchman, with the building seeing further elements removed and sold, and the building continuing to decay.
In 1997, the terminal, then in poor condition, was purchased by Scott Field of the Preservation Coalition of Erie County, whom paid for the building’s back taxes, and shortly thereafter, formed the Central Terminal Restoration Corporation, transferring ownership of the building to the organization. The building was stabilized and secured under the stewardship of the Central Terminal Restoration Corporation, which opened the building for public tours in 2003, and holds many fundraising events at the station every year. The building has been preserved, but a restoration or adaptive reuse of the structure has so far remained elusive.
The building features a brown brick exterior with an octagonal corner tower, with a large barrel-roofed main concourse structure wrapping around the tower to the south and east. The facade of the tower features multiple setbacks, chamfered corners, corner clock faces at the roofline above the twelfth floor, a rotunda with large archways and buttresses atop the tower with a decorative trim crown at the parapet, vertical window bays that stretch from the building’s base to the roofline, large entrances with metal canopies, large transoms, and stone surrounds, pilasters, and stone trim and caps atop the parapets. The main concourse portion of the building features large arched curtain walls at the ends of its barrel vaulted roof, a cavernous barrel vaulted interior, large metal canopies over the entrances, and a tunnel underneath that once allowed traffic on Curtiss Street to run beneath the building, though this has been closed since the 1980s due to the building’s decay, with a light court between the waiting room and a low-rise office block in the front, which sits just east of the tower and presents a similar facade treatment to that of the tower, with vertically accentuated window bays and pilasters. The rear of the building is more spartan in appearance, with a scar from the former location of the entrance to the train concourse to the rear, with the connecting structure having been removed following the discontinuation of railroad services at the building in 1979. The train concourse features multiple platforms with Art Deco-style aluminum canopies with sleek columns, thin-profile roofs, and rounded ends, with the train concourse featuring arched clerestory windows and a gabled roof, and being in a rather advanced state of deterioration with vegetation having grown throughout the structure and the surrounding abandoned tracks between the platforms. Attached to the southwest corner of the main building is the baggage building, a simpler six-story Art Deco-style structure with a buff brick exterior, a penthouse above the main entrance to the building, pilasters, vertically accentuated window bays, steel windows, stone spandrel panels, stone trim, and stone parapet caps, with long canopies along the base of the front and rear of the building that protected incoming and outgoing mail and baggage from inclement weather. To the west of the baggage building is the one-story mail processing building, which features a similar facade treatment, with the main difference besides height being the rooftop monitor windows in the middle of the building’s roof. Southwest of the baggage and mail processing building, sitting close to Memorial Drive, is a structure that formerly housed the Railway Express Agency, which is more utilitarian than the rest of the surviving complex, and is in an advanced state of decay, with the demolition of the structure being planned to take place sometime this decade. The structure features large window bays with steel windows, stucco cladding on the brick structure, and the remnants of canopies on the north and south facades of the first floor, with a long and low one-story wing to the rear.
The complex is one of the largest designed by Fellheimer & Wagner, and has maintained a remarkable state of preservation in its original form with few changes since its construction, besides some damage from the years of decay and neglect in the 1980s and 1990s. Another notable structure by the firm, and one of the most well-known railroad stations in the world, is Grand Central Terminal in New York City, which was also built for the New York Central Railroad. In addition to Grand Central Terminal, the firm also designed terminals that are more similar in appearance to the Buffalo Central Terminal, including Union Station in South Bend, Indiana, and Cincinnati Union Terminal, with Grand Central Terminal, Buffalo Central Terminal, and Cincinnati Union Terminal being among the largest, most impressive, and most significant railroad stations ever built in the United States. The station, though unrestored, is still impressive, and hopefully will be eventually adaptively reused for an economically sustainable function.
This is a photograph from the East of Ireland Marathon Series Marathon held at Stapelstown, Donadea, Naas, Co. Kildare, Ireland at 09:00 on Saturday 21st of September 2013. This is the first East of Ireland Marathon Series race outside of Dublin and also the first to have been run on rural roads and is race 5 of the East of Ireland Marathon Series 2013.
There was beautiful but warm weather in Stapelstown for the marathon which made conditions tougher than expected. The course brought runners on a loop from the village over towards Prosperous, Co. Kildare, and then back to the finish/refreshment area. The event was very well organised and whilst these races operate with a degree of self sufficiency for runners there was adequate marshalling, course marking, and refreshments available. Well done to all.
The East Of Ireland Marathon Series aims to make marathons affordable and convienient for the runners of Ireland. The serires organisers aim to promote marathon running and to make the process as stress free and enjoyable as possible. All courses are measured to full AAI standards and have a minimum of 10 Entrants. The marathons are self sufficent to a degree although there are limited supplies of water available on the day of the race. There will be no extra frills like chip timing and finish gantrys. However all finishing times are accurately and officially recorded. This is to keep the price down and keep the races as affordable as possible. The East of Ireland Marathon series is all inclusive and welcomes runners who are new to marathon running as well as experienced veterans.
This photograph is part of a Flickr set of photographs we took at this event. The Flickr set is available here [http://www.flickr.com/photos/peterm7/sets/72157635665725976/]. This set includes photographs from the start, in-race, and finish of the race.

Overall Race Summary
Participants: The East of Ireland marathon series stricly limits the number of participants. There were about 50 participants in the race today.
Weather: There was warm sunny weather for the race with competitors finding the humid conditions very tough as the race progress on around mid day. There was no real wind but a breeze which did help keep runners cool.
Course: The race started at St. Kevin's GAA and proceeded west into Stapelstown Village and reached a turnaround point which brought runners back to the starting point. This meant that runners then had to complete four complete loops of the 6.09 mile loop outlined below. This loop then proceeded directly southwards towards Prosperous but makes a sharp right turn before Properous village. This brings runners onto the Ballynafagh road and northwards back towards Stapelstown village. Runners then run down through the village (passing the finish and refreshment area) to complete the loop. The course is on traffic open country roads.

I ran in the race - but my photograph doesn't appear here in your Flickr set! What gives?
As mentioned above we take these photographs as a hobby and as a voluntary contribution to the running community in Ireland. Very often we have actually ran in the same race and then switched to photographer mode after we finished the race. Consequently, we feel that we have no obligations to capture a photograph of every participant in the race. However, we do try our very best to capture as many participants as possible. But this is sometimes not possible for a variety of reasons:
►You were hidden behind another participant as you passed our camera
►Weather or lighting conditions meant that we had some photographs with blurry content which we did not upload to our Flickr set
►There were too many people - some races attract thousands of participants and as amateur photographs we cannot hope to capture photographs of everyone
►We simply missed you - sorry about that - we did our best!
You can email us petermooney78 AT gmail DOT com to enquire if we have a photograph of you which didn't make the final Flickr selection for the race. But we cannot promise that there will be photograph there. As alternatives we advise you to contact the race organisers to enquire if there were (1) other photographs taking photographs at the race event or if (2) there were professional commercial sports photographers taking photographs which might have some photographs of you available for purchase. You might find some links for further information above.
Don't like your photograph here?
That's OK! We understand!
If, for any reason, you are not happy or comfortable with your picture appearing here in this photoset on Flickr then please email us at petermooney78 AT gmail DOT com and we will remove it as soon as possible. We give careful consideration to each photograph before uploading.
I want to tell people about these great photographs!
Great! Thank you! The best link to spread the word around is probably www.flickr.com/peterm7/sets
As expected the food was served on a tiered stand. The plate at the top contained most of the sandwiches and salty items (except for the sponge cake). It had the egg salad, bloaters, and cream cheese sandwiches. Sadly, it didn't contain cucumber sandwiches.
The second tier contained the scones. They were served with clotted cream and jam.
The last plate contained the sweet items. No Battenberg or fruit cake for us. Instead, we had lemon poppy seed cupcakes, macaroons and pecan squares. The plate contained a small dish of chocolate sauce.
Found some monarch eggs on our milkweed. We brought them inside to see if we can raise some butterflies.
'Expecting' was inspired by the close arrival of my first grandchild. It brings back like yesterday the anticipation of a new little bundle of love as I reflect on my own three children represented by the three birds nestled in the arm of the woman. Words of her inner thoughts peep through layers of paint on her swollen stomach.
This piece is 12x24" and is ready to be hung with the sides staple free and painted.
Expect things to get messy every time a toilet gets clogged. Good thing that most toilet clogging problems are simple and, most of the time, would not need the help of an emergency plumber. We have compiled simple steps to fix a clogged toilet in Cambridge. Your toilet will be...
Much Hadham is a lovely church being much larger than one would expect for its village setting. The church guidebook acknowledges this and points out that the site was owned by the Bishops of London since some date after 952 AD when it was gifted by Saxon Queen Ethelfleda in her will - first to her sister and her brother-in-law Brithnoth, the alderman of Essex - and then to the Bishop after her relative's deaths. I think this is same Brithnoth (spelled variously) who died leading the Saxon resistance against the Vikings at the Battle of Maldon in 991 - see my Maldon church set earlier.
www.flickr.com/photos/barryslemmings/sets/72157630026001994/ to see the full set.
A Bishops' Palace was built nearby and the presence of that palace, and the desire of various London bishops for a more substantial church, led to the construction of the present church which the guidebook admits would not look out of place in a well-to-do town like Ware or Hertford. The building is 121 feet long and the tower is topped with a stiletto-like thin spire called a 'Hertfordshire Spike'.
Dedicated to St Andrew, the present church was almost certainly a Saxo-Norman site but nothing survives today earlier than about 1225. Frustratingly no documents survive before the 19th century as the records should have been in Fulham Palace's archives and should have been transferred to the Guildhall Library in London. Fulham Palace is the main London home of the Bishops of London. An on-site investigation has revealed three phases of construction which - for argument's sake - have been called 13th, 14th and 15th century. It is not possible to ascribe accurate dates to these phases (so far) but future dendrochronology could be used to date the roof timbers with some accuracy and might result in a clearer architectural history.
The oldest part of the church is a weathered door which has now been moved inside and is thought to date to about 1225. It was moved about 100 years later and cut down to fit. Sometime after 1225 the chancel was greatly expanded and this may have been enlarged to allow the bishop and his chaplains to carry out the elaborate rituals which would not fit into a narrow Norman-style chancel. This chancel is Early English in style. Some time later the expansion of the nave was commenced (say 1240-1250) with the building of the south aisle. The first three arches on the south side set the scale for this work and may have been the work of a London mason supplied by the Bishop. This enlargement work continued until around 1280 with two more simpler arches being built on the south side.
Moving into the 14th century (the Decorated style) windows were improved and the north aisle was commenced. In common with many other churches in England the Black Death, in the 1340s, would have brought a halt to any other work as a substantial proportion of the population died along with many skilled artisans. In some English churches it is possible to see where this work halted during the plague. Work at Much Hadham restarted in the Perpendicular style (1390 to 1450). The 90-foot tall west tower carries the arms of Bishop Braybrooke (died 1404) so his arms may date that work at least. Also added were the south porch, a clerestory to the nave and the enlarged east window.
The main furnishings of the church such as the font, some pews, the screen and stalls also date to the 15th century. The pulpit looks like it was made from medieval material but was probably constructed during in the reign of Elizabeth I.
Mark and Michelle - expecting a new bundle of joy at the end of January. This session was done too early. Michelle wasnt showing much. A very fun couple to work with. We tried to schedule a 2nd session without any luck. FUN NOTE: I was the first to know the baby's name!!!!
I expected to see the blue ocean and tropical landscape. However, I was surprised at how many unexpected artistic touches I found around every corner. Honolulu, I love you!
Wow I don't think anyone expected this.
I was in bed about 11.30pm last night, just gone over to sleep when I got a text message from a friend saying he was dead, but I thought it was another one of these crap jokes that go around from time to time about him. I expected to get the rest of this "joke" but it never came so I went down stairs to put Sky News on and there it was. I couldn't believe what I was seeing, I wondered if the reports were blown up, but no it's all true!
I'm not a huge fan, I thought Billie Jean is the best thing he did, also the albums Off The Wall and Thriller are the best I think but after that from Bad onwards I think he lost a little of his magic. The media are speculating right now on what caused his heart attack saying it was prescription drugs, they are talking about his life and bringing up all the controversy that featured in his later years and dragging up all of the bad parts of his life as well as the good stuff. They are even talking about the fact he changed from black to white, leaving his roots behind!
Last night they were comparing his death to John Lennon but as they said, you can't do that as Lennon was murdered. I think it reminds me more of when Elvis Presley died, although I was about 12 when he died but I remember people crying about his death. Let's hope they find out the truth soon and they let him rest in peace

The past 4 days have been spent in wonderful Iceland and I took far too many shots, so expect to see A LOT of Iceland shots in the coming weeks :p I also should point out that we booked this trip months before the collapse of their economy!
This was taken on the first night we were there. Taking advice from Tripadvisor.com, we booked a trip with Sigi at Superjeep and he took us out hunting these mysterious lights. In order to see these things, you need to have a clear night and also are reliant on there being solar flares a couple of days before you are there. Sadly the sun has not been flaring much recently and combined with a cloudy(ish) night we didn't get to see any lights. My camera, on the other hand, did!
I promise I haven't tweaked this in photoshop, the green is natural as is the big dipper in the top left. It's grainy due to the high iso and looked better in my camera screen, but I'm still happy with it considering the human eye couldn't see it :)
Über 3.000 Menschen demonstrierten am 29. Januar 2011 für den Erhalt des seit über 20 Jahren existierenden Hausprojektes Liebig 14. Nach verfassungswidrigen Vorkontrollen und Festnahmen durch die Polizei und einem Redebeitrag setzte sich die Demonstration am Kottbusser Tor in Richtung Warschauer Straße lautstark in Bewegung. Viele an der Demorroute liegende Hausprojekte und Mieter_innen solidarisierten sich mit Transparenten mit der Liebig 14. Die etwa 650 Polizist_innen übten sich die meiste Zeit in Zurückhaltung, nahmen jedoch kurz vor dem Frankfurter Tor einige Menschen fest, was zu Flaschen-, Böller-, und Steinwürfen aus der Demonstration heraus führte.
An der Ecke Rigaerstraße/Liebigstraße sorgten Musik, Feuerwerk und Bengalos auf den Dächern für gute Stimmung unter den Demonstrant_innen. Anschließend wurde die wieder anrückende Polizei mit Steinen, Flaschen und Böllern auf Abstand gehalten und Barrikaden aus Bauzäunen und Dixi-Klos auf der Rigaerstraße errichtet. Die Polizei ging mit aller Härte gegen Demonstrant_innen vor, verletzte dabei willkürlich mehrere Menschen und nahm etwa 20 fest.
Die Demonstration dürfte einen kleinen Vorgeschmack auf die am 2. Februar drohende Räumung der Liebig 14 darstellen...
Singer-songwriters are generally not a huge draw for me. They have to jump over some pretty high hurdles for me to want to listen closer. I take words pretty seriously, and I expect chords, music, and delivery to engage my intellect and musical passion simultaneously. That's why this fellow--name of Bruce Cockburn (pronounced "Coh-burn," thank you very much!)--took me by surprise. I remember clearly hearing my brother-in-law's copy of this album. The jazz bass on "Incandescent Blue" by Robert Boucher really caught my ears. I liked how Cockburn keeps things open so the bass can offer commentary.
Canadian Cockburn has fashioned a long and highly creative career in a world that steadfastly ignores him. I believe "If I Had a Rocket Launcher" got him a slice of notoriety, but for the most part his vulnerable and honest exploration of life from the viewpoint of--for want of better words--a leftist spirituality seems to be too much for the Industry. Intelligence is oft considered a detriment in vast domains of infotainment, and the guy is probably too principled to compromise for the sake of stardom.
At any rate, Dancing in the Dragon's Jaws was a sweet introduction. Unabashed melody, wonder, optimism, and a poet's eye graces the grooves in the vinyl. After living off a cassette for many years, I picked up my long-playing phonograph copy from the long-lamentedly-gone Aron's records in Hollywood for a whopping 29 cents (which demonstrates how much Cockburn's valued by the world at large).
In his own notes Cockburn claims the content of some the songs herein were influenced by the writings of Charles Williams, whose admirers included W.H Auden, T.S. Eliot, and who was one of the so-called Inklings, a group which included J.R.R. Tolkein and C.S. Lewis. Novelist Williams
www.crossroad.to/Excerpts/books/lewis/inklings-williams.htm
was a complex thinker, who rubbed shoulders with Golden Dawn and Rosy Cross initiates while staunchly maintaining his Anglican adherence. As editor of Oxford University Press, he introduced the works of Søren Kierkegaard to the English-speaking world.
There is an over-arching manichaeism
en.wikipedia.org/wiki/Manichaeism
to Williams' works, and also in Bruce Cockburn's. Perhaps that's part of why I find the singer so compelling, whether or not I can always agree with him. He channels a force for good, which goes straight to his voice and lights a kind of fire. May that fire warm us and keep him--and us--dancing in this dragon jaw of a world!

Expect media blitz next weekend.
Incidentally, this means I shall have to post the English edition to young Daniel in Miami, because there is a simplified Amercan version they get. Also I have just found out the audio version in the US is read by someone other than Stephen Fry! Better send him CDs too.
Sunday.
Last day of 12 days off, and a day in which we were expected to have heavy thundery showers all afternoon, so had better do something in the morning.
And after breakfast that something was to go to Sandwich Bay, because of Lizard Orchids and check on the Marsh helleborines.
Jools wanted to go swimming, so I said I'd drop her off at the pool on the way, as Sandwich is a 15 minute blast away, so the plan was set.
It was a cloudy start, so there'd be no butterflies or dragonflies, and Jools had found my pass for the estate which I had to exchange for a sticker, meaning free entry all year as long as I park at the observatory.
There was the Women's Open Gold tournament on, so for a while I thought I might not be able to get across the course, but turned out that was at the other links course.
Yay.
I walked over the meadow and past the ringing area, and into the area of dune slacks at the Helleborines grow in. And at first I saw none, then once I got my orchid eye in, I saw hundreds of rosettes all around, some putting up a spike in the usual helleborine way.
There were dozens of Southern Marsh around to, which I learned this week, along with the Northern Marsh, have had their species status downgraded to sub-species, that of Broad Leaved Marsh Orchid (Dactylorhiza majalis).
Confusing.
Anyway, from there I took the path across the three fairways of the golf course, dodging flying balls and dressed in ridiculous clothes of pastel shades, heading for the safety of the gate onto the Strand.
On the way there were several Lizard spikes, and so more on the dunes beside the road. I snap many, but after a while was happy, so turned back for the car.
On the way back I saw another plant I had been looking for, Grass vetchling, a tall, willowy plant with a single pink pea-shaped flower, and being a windless day, was able to get a good shot of the flower.
Back then to the observatory, and as the sun had come out, a few butterflies were seen: Large Skipper, Small Skipper, Small tortoiseshell, and a single Dainty damsel having ventured far from her pond.
I went inside to get a drink, and met with John who helped arrange our trip to Svalbard, and we swapped news of things I saw on the trip after the one he did. We were very lucky, as we saw seven bears, his cruise saw just the one, and no Beluga.
Time was slipping, so I bid him farewell, and drove back to Whitfield where Jools was having a coffee in Subway.
I found three orchids she said, so we went to look, and three tall CSO spikes were growing in the formal border in front of the self-storage place.
We had to rush home, as Jen was back home, and back with Sylv, and we had been invited for Sunday dinner at one. So, we had to dash home so Jools could change, then drive to Whitfield to be on time.
Once there we admired the new skylight Mike had installed because the old one leaked, and we swapped news of things we have done. We regaled them with tales of the frozen north, of course.
Dinner was roast lamb, which was welcome, even if it was very hot in the house with both ovens going. We ate well, drank wine and made merry.
After eating, we could hear the rain falling, and we had left washing out on the line, so we made our excuses and went home.
The storm radar showed storms over Normandy, slowly drifting north and east, but slowly due to the light winds. We heard rumbles, but no storm arrived, though the rain did fall for hours.
We had butter fried asparagus for supper, before I watched yet more football: Spain v Croatia. Which isn't the last game of last season, as England play on Monday. And for those asking when the new season starts, I believe that to be Saturday when the preliminary rounds of the Champion's League start.
sigh.

The Southern Marsh-orchid is tolerant of a wide range of predominantly alkaline habitats, but occasionally it strays into mildly acidic parts of bogs and damp heaths. Best known in the south and often found on riversides and in damp meadows, this orchid also grows in abandoned quarries, on roadside verges and in some old industrial sites; in suitable places it can occur in large numbers. Dactylorhiza praetermissa is extremely variable in appearance and readily hybridises with spotted orchids, causing much confusion during identification. A 'typical' plant would be a robust, thick-stemmed orchid with broad unmarked leaves and relatively large pink-to-purple flowers. It is worth bearing in mind, however, that very small plants can also occur in drier marginal habitats such as chalk grassland. In Britain and Ireland, the Southern Marsh-orchid flowers between mid May and mid July. This species is endemic to Europe, and on the mainland it can be found in Scandinavia, northern France and southwards as far as northern Italy.
Plant: 20 to 70cm tall, but the larger plants may be due to hybridisation with other species. The stem is markedly stout, green and hollow.
Leaves: up to 9 flat sheathing leaves, which are greyish-green and unmarked and which vary greatly in width. There are also up to 3 narrower and more pointed leaves higher on the stem.
Bracts: green, washed purple.
Flowers: pink to purple; normally between 20 and 60 on a single inflorescence but up to 100 on very large plants. The upper sepal and petals form a loose hood over the lip, which is broad and almost circular, shallowly tri-lobed, with broad and rounded lateral lobes that often appear 'folded backwards' and a small, pointed central lobe. The lip is mainly pink, becoming white towards the base, and its centre is finely marked with dots and dashes.
Subspecies: none.
Varieties: Dactylorhiza praetermissa var. albiflora has white flowers and is rare. Dactylorhiza praetermissa var. macrantha has large flowers on a lax spike and its flower lips have a larger central lobe; it is found with Narrow-leaved Marsh-orchid Dactylorhiza traunsteinerioides and could be an intermediate between the two species. Dactylorhiza praetermissa var. bowmanii is a slender plant with narrower and fewer leaves and is sometimes confused with Narrow-leaved Marsh-orchid Dactylorhiza traunsteineriodes; it has been reported from Hampshire and Dorset.

Didn't expect to see this magnificent Western when I turned up at Plymouth station but which Western was it? I thought it was Western Renown as that's what it said on the name plate but on the other side of the train the name plate had Western Champion. (See my photo - Champion?) Anyone able to enlighten me on this one?
On the 11th April 2018 I visited Hythe village for the very first time. Not really knowing what to expect I found it a very beautiful village on the banks of the Southampton water. Hythe is a town near Southampton, Hampshire. It is located by the shore of Southampton Water, and has a ferry service connecting it to Southampton. Hythe has a small shopping area, a pier, and a very picturesque marina for yachts.
The name Hythe means landing place or haven. Hythe is recorded in a Parliamentary roll from 1293. The Hythe ferry to Southampton is marked on a map by Christopher Saxton of 1575, and on a map by John Harrison in 1788. Hythe was part of the parish of Fawley, although it became a separate parish in 1841. The current church, of Saint John the Baptist, was erected in 1874. It is of red brick with Bath Stone dressings. There were at one time even stocks in the village.
Thanks in part to the British Power Boat Company and it’s excellent access to the English Channel, during World War II Hythe was used as a port for the little ships of the Royal Navy as they were then known, the Motor Torpedo Boats and the RAF Air Sea Rescue Boats. In 1960, The Hovercraft Development Company and Sir Christopher Cockerell, who was the founder, moved to Hythe, he did in fact live in one of the houses near to the marina. There was also a small Royal Air Force base in Hythe known as RAF Hythe. Until its closure in September 2006 it was used by the United States Army to service and maintain watercraft.
Hythe was a village up to the 1950’s, but the expansion of Fawley Refinery, now closed, led to a demand for more houses for workers, and Hythe and Dibden Purlieu were allowed to expand into a small town. In 1983, following the growth of Hythe, the parish of Dibden was renamed to Hythe and Dibden, to reflect the importance of Hythe as a new focal point of the Parish
Hythe has a small shopping area clustered around the High Street, which includes a Waitrose Supermarket, a public library, several charity shops, and various small independent retail shops and cafes. The Hythe Pier, Railway and Ferry operates across Southampton Water to Southampton, and is the oldest working pier train in the world. Hythe's position makes it a good viewing point for watching ocean liners arriving and departing at the port of Southampton, which attracts ship spotters to the area. Hythe has a marina, at which a large number of yachts and boats are moored. Large and expensive houses are situated around the marina, overlooking the waterside. This is controlled by large lock gates at the entrance leading out to Southampton Water.
The pier, railway and ferry service are currently operated by Blue Funnel Ferries of Southampton. In October 2016 the previous owners ( White Horse Ferries ) warned their staff of potential redundancy which suggested an uncertain future from the pier and ferry service. After months of talks, Mr. Lee Rayment of Blue Funnel Ferries completed negotiations to acquire the Pier, Train and Ferry with operations starting on 21 April 2017. The railway is the oldest continuously operating public pier train in the world. Hythe Pier stretches 700 yards ( 640 metres ) from the centre of Hythe to the deep water channel of Southampton Water. It is approximately 16 feet ( 4.9 metres) wide, and carries a pedestrian walkway and cycle~way on its northern side and the Hythe Pier Railway on its southern side. During normal high tides the pier is 4 feet ( 1.2 metres ) above the surface of the water. In 1922 the railway was finally reconstructed and electrified, attaining its current form as seen today. The track is laid to 2 ft ( 610 mm ) narrow gauge and is electrified at 250 V DC by a third rail on the seaward side of the track.
You were expecting St. Peter? Well, not in this part of Heaven....

Fangruida: human landing on Mars 10 cutting-edge technology
[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.

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.

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.
Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites
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.
Hierarchy
The crust
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.

Calcium 8%
Aluminum 7%
Magnesium 6%
Other 3%
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.

I didn't expect the skin behind the neck to be so loose in adult cats. I thought it was a kitten thing :)
I did not expect to see an ivy covered building on the beach. I know it is a nightmare to take care of in the tropics. I think of all the bugs and critters that we have, slithering all over the wall. But it is beautiful.
