The Times has got an awesome slideshow up featuring a collection of spacesuits, presented in both photographed and X-rayed form. Some were actually used on missions, others never left the planet, some look hi-tech, others look like you shouldn't wear them in a rainstorm. They're all part of the Smithsonian's collection, and they're reportedly planning a traveling exhibition for Spring 2011, though no information yet exists on their website.
In the meantime, check out the images and related article, the latter of which features a cool blown-up shot with call-outs.
