Bowen during EVA 3

S126-E-009029 (22 Nov. 2008) --- Almost "lost" among this massive array of International Space Station hardware is astronaut Steve Bowen as he participates in the STS-126 mission's third scheduled session of extravehicular activity (EVA). During the six-hour, 57-minute spacewalk, Bowen and astronaut Heidemarie Stefanyshyn-Piper (out of frame), both mission specialists, focused their efforts on the continued cleaning of the station's starboard solar alpha rotary joint (SARJ) and the removal and replacement of trundle bearing assemblies (TBA). Bowen and Piper also cleaned the area around the SARJ's drive lock assemblies, which help the joint to rotate and lock into place.
