Shuttle Discovery's launch tomorrow at 4:50 p.m. EST

At today's pre-launch news conference NASA's mission management team have given their unanimous approval for space shuttle Discovery's launch tomorrow at 4:50 p.m. EST.   "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."

Weather forecast good

The weather at the launch site 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 is also looking good.

NASA TV Coverage

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.
