The three hour fueling process to get nearly 500,000 gallons of super cold fuels into space shuttle Endeavour's fuel tank was completed at 12:49 pm EDT, as NASA remains go for launch tonight.
The external tank, which consists of two inner tanks for both liquid oxygen and liquid hydrogen, will slowly refill the tanks through out the afternoon as the fuels burn off and evaporate.
Delayed three times due to weather and a leaking gaseous hydrogen valve in June, Endeavour (above at 1:38 pm) looked very fit as NASA moved past the point in fueling where they began to see the leaking GH2 during two launch attempts last month.
The crew of Endeavour have been awake for four hours now, and will eat a bite before beginning to dress in their launch suits at 2:50 pm.
At 1:40 pm, Endeavour's commander Mark "Roman" Polansky stated, "Still looking good for today's launch. (We) Had a final crew meeting, and next up is our weather brief at 1430 (2:30 pm ET). Then, suit up".
Launch remains set for 7:13:55 pm EDT, this evening.
