STS-119 EVA#2 Swanson and Acaba Installation antenna GP FINAL EVA#2 Steve Swanson and Joseph Acaba Astronauts Steve Swanson and Joseph Acaba ended the mission’s second spacewalk at 7:21 pm EDT. They prepared a worksite so that 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. After struggling with a balky pin that kept an unpressurized cargo carrier attachment system (UCCAS) from fully deploying, they tied UCCAS safely in place. Engineers will evaluate the issue. Today’s spacewalk lasted six hours, 30 minutes. It was Swanson’s fourth spacewalk and Acaba’s first, and the 122nd spacewalk in support of station assembly and maintenance, totaling 768 hours, 33 minutes. NASA Television will carry a news briefing at 8 pm with STS-119 Lead Space Station Flight Director Kwatsi Alibaruho and STS-119 Lead Extravehicular Activity Officer Glenda Laws-Brown.
