The rotating service structure has been rolled away from space shuttle Endeavour in a major milestone leading up to launch. The liftoff of Endeavour on the STS-123 mission remains on schedule for 2:28 a.m. EDT Tuesday, March 11.

The movement of the enclosed gantry clears the way for the loading of about 500,000 gallons of supercold liquid oxygen and liquid hydrogen propellants into the orange external tank this evening.

The rotating service structure provides weather protection to the shuttles at the launch pad and gives technicians access to the shuttle.

The current weather forecast calls for only a 10 percent chance atmospheric conditions will delay the launch, with the primary concern coming from a slight chance of a low cloud ceiling around Kennedy.

The flight is commanded by Dominic Gorie with Gregory H. Johnson serving as Pilot. The crew also includes Mission Specialists Rick Linnehan, Robert L. Behnken, Mike Foreman, Garrett Reisman and Japanese astronaut Takao Doi.

The crew will deliver the first section of the Japanese-built Kibo laboratory and the Canadian Space Agency's two-armed robotic system called Dextre.

STS-123 is an international mission combining the expertise and experience of several countries working together to create a working 'home' in space.
