During a Google+ Hangout NASA announced its newest class of astronaut trainees. The eight candidates selected to the 2013 astronaut class were chosen from a pool of 63-hundred applications -- the second largest NASA has ever received. In August, the group will begin a wide array of technical training at Johnson Space Center, other NASA centers and space agencies around the world.
