The loading of the space shuttle’s external tank with 500,000 gallons of liquid oxygen and hydrogen began at 6:22 p.m. EDT, and the "topping off" of the tank’s propellants will continue until launch time. All systems onboard Endeavour are functioning normally.
There is a 70 percent chance of favorable weather for launch. The primary weather concern is for low cloud ceilings and crosswinds at the Shuttle Landing Facility
Launch is targeted for 3:47:55 p.m.
