ISS032-E-025163 (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 (visible in the reflections of Hoshide?s helmet visor), 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.
