Space shuttle Endeavour's external fuel tank is being filled with more than 500,000 gallons of liquid hydrogen and liquid oxygen. The three-hour operation began at 11:04 p.m. EDT. The Liquid Hydrogen Low Level Cutoff (LLCO) sensors will go "wet" at about 11:49 p.m. The tank will be completely filled, known as stable replenish, at about 2:04 a.m.
The launch countdown currently is holding at T-3 hours, which will last until 1:45 a.m. EDT.
There still is a 80 percent chance that weather will not affect the 5:40 a.m. launch of STS-127.
