STS-119 EVA 2 JLP GPS Antenna Install OPS

S119-E-006858 (21 March 2009) --- Astronaut Steve Swanson, STS-119 mission specialist, participates in the mission's second scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 30-minute spacewalk Swanson and astronaut Joseph Acaba (out of frame), mission specialist, prepared a worksite so the STS-127 spacewalkers can more easily change out the Port 6 truss batteries later this year. On the Japanese Kibo laboratory they installed a second Global Positioning Satellite antenna that will be used for the planned rendezvous of the Japanese HTV cargo ship in September. They photographed areas of radiator panels extended from the Port 1 and Starboard 1 trusses and reconfigured connectors at a patch panel on the Zenith 1 truss that power Control Moment Gyroscopes.
