NASA ISS EVA: All in a Day's Work

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.
