Sunita Williams on Spacewalk
NASA astronaut Sunita Williams, Expedition 32 flight engineer, appears to touch the bright sun during the missionâ€™s third session of extravehicular activity (EVA) on Sept. 5, 2012.
During the six-hour, 28-minute spacewalk, Williams and Japan Aerospace Exploration Agency astronaut Aki Hoshide (visible in the reflections of Williamsâ€™ helmet visor), flight engineer, completed the installation of a Main Bus Switching Unit (MBSU) that was hampered by a possible misalignment and damaged threads where a bolt must be placed. They also installed a camera on the International Space Stationâ€™s robotic arm, Canadarm2.
