The countdown for the Space Shuttle Discovery launch began at 5 p.m. Wednesday at the T-43 hour mark. The launch control team members are in Firing Room 4 of the Launch Control Center monitoring the system consoles. Launch remains scheduled for Saturday at 3:49 p.m.
The entire STS-121 crew participated in flight training this morning in T-38 jets. The commander and pilot also practiced landing techniques in the Shuttle Training Aircraft.
At Launch Pad 39B, preparations for the launch of STS-121 continue. Early stowage of items in the flight crew cabin is complete. Loading of fuel cell reactants is scheduled to pick up later today. The fuel cells provide electricity to the orbiter during flight.
The Mission Management Team met this afternoon for the traditional launch readiness meeting and gave the approval for a launch attempt on Saturday.
U.S. Air Force weather officers are forecasting a 60-percent chance of weather prohibiting a launch attempt on Saturday. The primary weather concerns are anvil clouds from inland thunderstorms, cumulus clouds within 10 nautical miles of the flight path, and showers within 20 nautical miles of the Shuttle Landing Facility. The forecast is similar in the event of a 24-hour delay.
