STS-122, February 2008
European Space Agency (ESA) astronaut Hans Schlegel, STS-122 mission specialist, participates in the mission's second scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 45-minute spacewalk, among other tasks, Schlegel and NASA astronaut Rex Walheim (out of frame), mission specialist, worked to replace a nitrogen tank used to pressurize the station's ammonia cooling system.
