March 5, 2018 - A Foothold in Space

A Foothold in Space  Anchored to a Canadarm2 mobile foot restraint, astronaut Rick Linnehan participates in the first scheduled spacewalk of the STS-123 mission, which began ten years ago this week. During the seven-hour spacewalk outside the ISS, Linnehan and astronaut Garrett Reisman (out of frame) prepared the Japanese logistics module-pressurized section for removal from space shuttle Endeavour’s payload bay, opened the Centerline Berthing Camera System on top of the ISS Harmony module, removed the Passive Common Berthing Mechanism, and installed two Orbital Replacement Unit tool change-out mechanisms on the Canadian-built Dextre robotic system, the final element of the station’s Mobile Servicing System. STS-123 spent 16 days in space, 12 of them docked to the ISS.
