The rotating service structure (RSS) on NASA Kennedy Space Center’s Launch Pad 39A is fully open and moved away from space shuttle Endeavour. The RSS began moving at 11:44 a.m. EDT, about 15 minutes ahead of schedule. The retraction was complete at 12:24 p.m.
Final preparations continue for Endeavour’s 8:56 a.m. Monday liftoff. Cockpit switches will be configured this afternoon, while Commander Mark Kelly and his crew will begin their launch sleep schedule at 4 p.m.
The shuttle’s electricity-producing fuel cells will be activated at 5:46 p.m. and managers will meet at 11 p.m. to give a "Go-No Go" to load the External Fuel Tank with liquid hydrogen and liquid oxygen.
Coverage of the fuel loading begins at 11:30 p.m. on NASA TV and at www.nasa.gov/ntv. The tanking process is scheduled to begin at 11:36 p.m.
At 12 a.m. Monday, Endeavour’s crew wakes up for launch.
