NASA prepares for shuttle's liftoff
CAPE CANAVERAL — Late Tuesday night, NASA began fueling space shuttle Endeavour for a launch to the International Space Station early today.
Fueling was delayed nearly three hours because of thunderstorms. The weather finally eased, and managers gave the go-ahead to begin filling Endeavour's external tank. Meeting the 5:40 a.m. liftoff time may be difficult — the fueling began just when it should have been ending.
It is NASA's second attempt to launch Endeavour. A hydrogen gas leak spoiled Saturday's try.
This is the last chance for NASA to launch Endeavour before standing down for an unmanned moon shot. A delay would bump the shuttle flight into July.
