About Photo: Anchored to a Canadarm2 mobile foot restraint, astronaut Rick Linnehan participates in the mission's first scheduled spacewalk. During the seven-hour spacewalk, Linnehan and Expedition 16 flight engineer Garrett Reisman prepared the Japanese logistics module-pressurized section for removal from Endeavour's payload bay and installed the tool change out mechanisms on the Canadian-built Dextre robotic system, the final element of the station's Mobile Servicing System.
