A fisheye lens attached to an electronic still camera was used to capture this image of NASA astronaut Sunita Williams, Expedition 32 flight engineer, during 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. A portion of the space station, Earth?s horizon and the blackness of space provide the backdrop for the scene.
