Astronauts Steve Swanson and Joseph Acaba (out of frame) 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 GPS antenna that will be used for the planned rendezvous of the Japanese HTV cargo ship in September.
Astronauts Steve Swanson and Joseph Acaba (out of frame) 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. This was the STS-119 mission’s second spacewalk.
Acaba and Richard Arnold will perform the mission’s third spacewalk on Monday, March 23, 2009.Image Credit: NASA
