Comet Enthusiast

Astronaut Greg Chamitoff made his way inside the station as Andrew Feustel awaited his turn at the end of the STS-134 mission's first spacewalk. The Endeavour astronauts completed a 6-hour, 19-minute spacewalk at the International Space Station Friday, May 20, 2011, retrieving materials experiments and installing another, and installing an antenna. They also installed a light on a station handcart, set up equipment for adding ammonia to a cooling loop and installed a cover on a rotary joint for solar arrays. Image Credit: NASA
