Endeavour's External Tank Fully Fueled

Endeavour's external fuel tank has been filled with more than 500,000 gallons of chilled liquid oxygen and liquid hydrogen propellants. The shuttle's trio of main engines will draw from the external tank during the push to orbit. There are no indications of a leak, and fueling has entered the "stable replenish" mode. Countdown clocks have entered a planned hold at T-3 hours and everything remains on schedule for a 7:13 p.m. EDT launch of Endeavour from NASA's Kennedy Space Center in Florida. More
