Astronauts Train in Maine
NASA's Jack Fischer, astronaut class of 2009, is waiting for his chance to fly into space. But before anyone can get strapped to a rocket and sent into the near-vacuum of space, an astronaut has to prove he or she can survive down here on the ground. Fischer recently tweeted this photo from his wilderness training in Maine, where astronaut candidates learn to work together and trust each other, much like they'll have to later 200 miles high performing spacewalks in low-Earth orbit.
