Discovery Ready for Landing

Space shuttle Discovery underwent the Flight Control System checkout and Reaction Control System hotfire using all the primary jets. A piece of debris jarred loose from the shuttle during the checkout, though it was determined not to be a piece of the thermal protection system. Late inspection results cleared Discovery's wing leading edge and nose cap and the shuttle is ready for landing.

Thursday's landing opportunities begin with a planned deorbit burn at 5:59 p.m. EDT and a daylight landing at 7:05 p.m. The next opportunity is one hour after sunset with the deorbit burn at 7:36 p.m. EDT and a landing at 8:42 p.m. EDT.
