STS 127 Rotating Service Structure Roll Back Time Lapse

Space shuttle Endeavour is in launch position at NASA's Kennedy Space Center in Florida following rollback of the Launch Pad 39A rotating service structure.

Endeavour is scheduled to lift off at 5:40 a.m. EDT Wednesday, beginning its STS-127 mission. At 1:15 p.m. today, clocks will begin counting back from T-11 hours toward launch.

The mission management team is scheduled to meet at 7:30 p.m. to give the "go/no-go" to begin loading Endeavour's external fuel tank with liquid propellants. With managers' approval, fueling will begin at 8:15 p.m.
