Launch No Earlier Than Dec. 3 at About 2:52 a.m.

At today’s Program Requirements Control Board, or PRCB, the Space Shuttle Program clearly identified the analysis and repairs that are required to safely launch shuttle Discovery on its STS-133 mission. This analysis will be in work during the next five days and will be reviewed at a special PRCB on Wednesday, Nov. 24. Pending a successful review of the flight rationale at that meeting, a Launch Status Briefing would be held with senior NASA management on Monday, Nov. 29.

The Launch Status Briefing and news conference planned for Monday, Nov. 22 are cancelled.

The Kennedy Space Center “Call-to-Stations” to begin the launch countdown will be no earlier than Nov. 30, supporting a first launch attempt no earlier than Dec. 3 at about 2:52 a.m. EST.
