Participating in the STS-129 mission's first spacewalk in November 2009, astronauts Mike Foreman and Robert L. Satcher Jr. (out of frame) installed a spare S-band antenna structural assembly to the Z1 segment of the station's truss, or backbone. During the six-hour, 37-minute spacewalk, Foreman and Satcher also installed a set of cables for a future space-to-ground antenna on the Destiny laboratory. 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.
