ISS032-E-025174 (5 Sept. 2012) --- Japan Aerospace Exploration Agency astronaut Aki Hoshide, Expedition 32 flight engineer, participates in the mission's third session of extravehicular activity (EVA). During the six-hour, 28-minute spacewalk, Hoshide and NASA astronaut Sunita Williams (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. A cloud-covered part of Earth is visible in the background
