Space shuttle Discovery's external tank is being filled with more than 500,000 gallons of liquid hydrogen and liquid oxygen. The three-hour operation began at 11:56 a.m. EDT. There still is a 95 percent chance that weather will not affect the 9:20 p.m. launch of STS-119. The forecast also is favorable at the Kennedy Space Center Shuttle Landing Facility, Edwards Air Force Base in California and all three overseas Transatlantic sites, should an abort landing be necessary.
