In the darkness of space, European Space Agency astronaut Hans Schlegel participates in the mission's second spacewalk as construction and maintenance continue on the International Space Station. During the six-hour, 45-minute spacewalk, Schlegel and NASA astronaut Rex Walheim (out of frame) worked to replace a nitrogen tank used to pressurize the station's ammonia cooling system.
