Swanson and Acaba began the second spacewalk at 16:51 UTC.
They loosened bolts, installed foot restraints and prepared tools so that the STS-127 spacewalkers could 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.
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 pin that kept an Unpressurized Cargo Carrier Attachment System (UCCAS) from fully deploying, they tied UCCAS safely in place.
The spacewalk ended at 23:21 UTC, for a time of six hours and thirty minutes.
