STS-116 MS Curbeam during EVA-4 outside the Airlock

S116-E-06938 (18 Dec. 2006) --- Astronaut Robert L. Curbeam Jr., STS-116 mission specialist, exits the Quest Airlock of the International Space Station as he and European Space Agency (ESA) astronaut Christer Fuglesang (out of frame), mission specialist, begin the mission's fourth session of extravehicular activity (EVA) while Space Shuttle Discovery was docked with the station. Curbeam and Fuglesang worked in tandem, using specially-prepared, tape-insulated tools, to guide the array wing neatly inside its blanket box during the 6-hour, 38-minute spacewalk.
