As for working in a vacuum, I very much doubt that a conventional DSLR would work correctly -- if it worked at all, it probably wouldn't work for very long. You'd probably get outgassing from the lubricants used in the mechanical parts, there's a good chance the shutter would stick in place either due to that or other vacuum effects, the temperatures involved would probably go outside the camera's design parameters, and most likely the CCD would overheat.[a href=\"index.php?act=findpost&pid=149445\"][{POST_SNAPBACK}][/a]
To prepare a camera for use in the Arctic/Antarctic [in the off season!], you winterise it. This means removing all the lubricants, as they are not effective at such low temperatures. You would do the same for the mechanical aspects of DSLRs in space, if they have to go outside, that is.

I remember reading a report (a day or two before the D3 was officially announced) that NASA had purchased a large number of Nikon D2xs.

Not sure if these are for the space projects, anyway I think they are great pictures because of the content and the fact that they seemed to have been leaked all over the web! I wonder who'll be the first to get in trouble with copyright abuse!!!!!
