Sunita Williams spacewalk

NASA astronaut Sunita Williams, Expedition 32 flight engineer, appears to touch the bright sun on her mission’s third spacewalk on 5 September 2012. 
During the six-hour, 28-minute spacewalk, Sunita and Japanese astronaut Aki Hoshide (visible in the reflections of Sunita’s helmet) installed a Main Bus Switching Unit and a camera on the International Space Station’s robotic arm, Canadarm2.
