Discovery’s Fueling Continues

At NASA’s Kennedy Space Center in Florida, space shuttle Discovery is poised for liftoff from Launch Pad 39A. Filling of Discovery’s large, orange external fuel tank with chilled liquid oxygen and liquid hydrogen is currently under way. The propellants began flowing into the tank at 9:28 p.m. EDT, and moved to the “fast fill” phase at 10:18 p.m. The process generally takes about three hours to complete, and the propellants are then held in a “stable replenish” mode after that.

Weather is looking good, and launch remains scheduled for 6:21 a.m. Live launch coverage will begin on NASA TV and on NASA’s Launch Blog at 1:15 a.m. Monday. The Launch Blog can be found at www.nasa.gov/launch and NASA TV at www.nasa.gov/ntv.
