"Everything is on track and going beautifully with the countdown," said Mike Moses, mission management team chair. "We're really looking forward to a very action-packed, successful mission and everything is on track."
Mike Leinbach, shuttle launch director, agreed that everything is going extremely well with the launch countdown. He also acknowledged the processing teams who worked on Discovery, its flight systems and ground elements. "As we're powering up (the systems) we're seeing no problems at all."
The rotating service structure will be rolled away from Discovery at around 8 p.m. revealing it for the last time on the launch pad. Loading of the external fuel tank will begin at around 7:25 a.m. tomorrow morning. "We're not tracking any issues and it looks like Discovery will fly this time," said Leinbach.
Kathy Winters, shuttle weather officer, reported that the weather remains exceptional with only a 20 percent chance that weather will be prohibitive at launch time. The only slight issue may be a localized off-shore shower in the late afternoon. The forecast during tanking also is looking very good.
At 7:15 a.m. EST NASA TV will begin coverage of the fueling of the external tank. Launch coverage for Discovery's final mission to the International Space Station will begin at 11:30 a.m.
