S129-E-008248 (23 Nov. 2009) --- Astronauts Randy Bresnik (right) and Robert L. Satcher Jr. (top left), both STS-129 mission specialists, participate in the mission's third and final session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the five-hour, 42-minute spacewalk, Bresnik and Satcher removed a pair of micrometeoroid and orbital debris shields from the Quest airlock and strapped them to the External Stowage Platform #2, then moved an articulating foot restraint to the airlock, and released a bolt on a starboard truss ammonia tank assembly (ATA) in preparation for an STS-131 spacewalk that will replace the ATA.
