KENNEDY SPACE CENTER, FLA. -- In the Orbiter Processing Facility at NASA's Kennedy Space Center, space shuttle Endeavour's STS-123 Commander Dominic Gorie inspects the window in space shuttle Endeavour. The crew is at Kennedy for crew equipment interface test, a process of familiarization with payloads, hardware and the space shuttle. The STS-123 mission is targeted for launch on Feb. 14. It will be the 25th assembly flight of the station. Photo credit: NASA/Kim Shiflett

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility at NASA's Kennedy Space Center, members of space shuttle Endeavour's STS-123 crew, dressed in protective suits, get ready to inspect part of the payload for the mission, the Special Purpose Dexterous Manipulator, known as Dextre. At left is Commander Dominic Gorie and at center is Mission Specialist Michael Foreman. At right are Pilot Gregory Johnson and Mission Specialist Richard Linnehan. Dextre will work with the mobile base and Canadarm2 on the International Space Station to perform critical construction and maintenance tasks.
