Spaceman Mike Massimino
Retired NASA astronaut Mike Massimino flew two shuttle missions to repair the Hubble telescope and became the first person to tweet from space during his final spaceflight. To celebrate the launch of his new memoir "Spaceman," here are some awesome photos from his life in space and on Earth. THIS PHOTO: NASA astronaut Mike Massimino pauses for a photo in his spacesuit during a spacewalk outside the space shuttle Columbia on March 5, 2002. Massimino's two shuttle missions were focused on repairing the Hubble Space Telescope.
Deep water diving is essential to training for the weightlessness of outer space. Massimino and the rest of his crew practiced their five scheduled space walks in NASA’s Neutral Buoyancy Laboratory over the course of 18 months.
