Photo Gallery: Spacewalk closes book on shuttle era

Space station astronauts Mike Fossum and Ron Garan ventured outside the orbiting complex Tuesday to stow a failed cooling pump module in the payload bay of shuttle Atlantis and place a robotic satellite refueling demo experiment on the outside of the outpost. The astronauts also accomplished several bonus tasks during the six-hour, 31-minute spacewalk, the last of the space shuttle era. Photos: NASA
