Photos: EVA to Install a Main Bus Switching Unit
NASA astronaut Sunita Williams, Expedition 32 flight engineer, participates in the mission’s third session of extravehicular activity (EVA). During the six-hour, 28-minute spacewalk, Williams and Japan Aerospace Exploration Agency astronaut Aki Hoshide (out of frame), flight engineer, completed the installation of a Main Bus Switching Unit (MBSU) that was hampered last week by a possible misalignment and damaged threads where a bolt must be placed. They also installed a camera on the International Space Station’s robotic arm, Canadarm2. The thin blue line of Earth’s atmosphere and the blackness of space provide the backdrop for the scene.

Hoshide and Williams are partially attired in their Extravehicular Mobility Unit (EMU) spacesuits and are going through a pre-breathing period, which is a normal procedure for spacewalkers in preparation for their extravehicular activity (EVA).ISS032-E-024366 (29 Aug. 2012) — high res (1.7 M) low res (104 K)
