KENNEDY SPACE CENTER, FLA. -- The mobile launcher platform with space shuttle Endeavour on top comes to rest on Launch Pad 39A. Prior to launch on the STS-123 mission, Endeavour will undergo three weeks of processing at the pad. At left of the shuttle is the orbiter access arm with the White Room at the end. The arm will swing around so that the White Room rests next to the orbiter hatch, through which workers, the shuttle crew and closeout crew can enter the cockpit. The journey from the Vehicle Assembly Building began at 11:24 p.m. on Feb. 17, approximately 30 minutes before it's scheduled start time due to favorable weather conditions. The shuttle arrived at the launch pad at 4:45 a.m. Monday and was hard down at 6:22 a.m. On the mission, Endeavour and its crew will deliver the first section of the Japan Aerospace Exploration Agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre. Launch is targeted for March 11. Photo credit: NASA/Amanda Diller
