Astronaut Mike Foreman, STS-129 mission specialist, participates in the mission's first session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 37-minute spacewalk, Foreman and astronaut Robert L. Satcher Jr. (out of frame), mission specialist, installed a spare S-band antenna structural assembly to the Z1 segment of the station's truss, or backbone. Foreman and Satcher also installed a set of cables for a future space-to-ground antenna on the Destiny laboratory and replaced a handrail on the Unity node with a new bracket used to route an ammonia cable that will be needed for the Tranquility node when it is delivered next year. The two spacewalkers also repositioned a cable connector on Unity, checked S0 truss cable connections, and lubricated latching snares on the Kibo robotic arm and the station's mobile base system.
