Spacewalker

Anchored to a Canadarm2 mobile foot restraint Garrett Reisman conducts the mission’s first spacewalk. During the seven-hour, 25-minute spacewalk, Reisman and Steve Bowen installed a second antenna for high-speed Ku-band transmissions and added a spare parts platform to Dextre, a two-armed extension for the station’s robotic arm.
