Spacewalk (STS-123) Poster

Anchored to a Canadarm2 mobile foot restraint, astronaut Rick Linnehan, STS-123 mission specialist, participates in the mission's first scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the seven-hour and one-minute spacewalk, Linnehan and astronaut Garrett Reisman (out of frame), Expedition 16 flight engineer, prepared the Japanese logistics module-pressurized section (JLP) for removal from Space Shuttle Endeavour's payload bay; opened the Centerline Berthing Camera System on top of the Harmony module; removed the Passive Common Berthing Mechanism and installed both the Orbital Replacement Unit (ORU) tool change out mechanisms on the Canadian-built Dextre robotic system, the final element of the station's Mobile Servicing System.
