CAPE CANAVERAL, Fla. Crews at Cape Canaveral are getting ready to fuel up space shuttle Endeavour for a nighttime launch on a space station remodeling mission.
Liquid hydrogen and liquid oxygen are to begin flowing into the shuttle s external tanks at 10:30 a.m. Friday.
A cold front is on its way to Florida but NASA officials say there s about a 70 percent chance the weather will cooperate enough to go ahead with the 7:55 p.m. launch.
About a fourth of all shuttle missions start at night.
The shuttle s crew is heading to the international space station to deliver a new bathroom, kitchenette, an exercise machine, two bedrooms and a system capable of turning urine into drinking water.
