Shuttle missions rescheduled

NASA is targeting Nov. 1 for the launch of space shuttle Discovery's STS-133 mission and Feb. 26, 2011, for the liftoff of shuttle Endeavour's STS-134 flight from the Kennedy Space Center, Fla. The target dates were adjusted because critical payload hardware for STS-133 will not be ready in time to support the previously planned Sept. 16 launch. With STS-133 moving to November, STS-134 cannot fly as planned, so the next available launch window is in February. All target launch dates are subject to change.
