NASA managers late today cleared the shuttle Discovery for re-entry and landing Wednesday to close out a dramatic space station assembly mission, giving the ship's heat shield a clean bill of health after analyzing data from a final inspection. Entry Flight Director Bryan Lunney, son of legendary Apollo flight director Glynn Lunney, said Discovery's entry systems were checked out earlier today, and forecasters are predicting acceptable conditions with the only concern being relatively high headwinds on runway 33 at the Florida spaceport. Given the forecast, NASA is not activating the shuttle's backup landing sites at Edwards Air Force Base, Calif., or Northrup Strip, N.M. "We have KSC for two opportunities on Wednesday," Lunney said. "I do not have Edwards or Northrup called up at all Wednesday. If we wave off for weather or have some other problem, I'll make a determination Wednesday afternoon whether or not to call up Edwards on Thursday. So I'm not going to make that call until then." Assuming the weather holds and no problems develop, commander Pam Melroy and pilot George Zamka plan to fire Discovery's twin braking rockets at 11:59:12 a.m. for one minute and 58 seconds, slowing the ship by about 150 mph to drop out of orbit for an hourlong glide to Earth. Crossing the coast of North America just north of Vancouver, Discovery will follow a so-called descending node trajectory, plunging across the heartland of America for a landing at 1:01:50 p.m. A second landing opportunity is available one orbit later, with a deorbit rocket firing at 1:34:42 p.m. and landing at 2:36:12 p.m. The Spaceflight Meteorology Group at the Johnson Space Center in Houston, which is responsible for shuttle landing weather forecasts, predicted scattered clouds at 3,000 feet, visibility of 7 miles and winds out of 350 degrees at 14 knots with gusts to 23. That works out to a 22-knot headwind, just 3 mph below NASA's safety limit. "The weather right now is looking really, really good," Lunney said. "For the last few days, the forecast has been great. We've had mostly clear skies, we're forecasting scattered at 3,000 ... and the winds are going to be blowing right down the runway, peaking up to 23 (knots) with a 14-knot steady state. So real optimistic that tomorrow's landing opportunities we'll play out for us for weather." Here is a timeline of tomorrow's deorbit opportunities (in EST; the times for deorbit ignition and landing may change by a few seconds based on final tracking):
