CAPE CANAVERAL, Fla. (AP) — NASA says space shuttle Discovery is finally leak-free and ready to blast off Wednesday.
A pair of gas leaks resulted in back-to-back launch delays for Discovery. NASA test director Steve Payne said Sunday that repairs took care of the problem.
The countdown clocks will begin ticking Sunday afternoon, two days late. Liftoff is scheduled for 3:52 p.m. Wednesday. Forecasters put the odds of good weather at 70 percent.
Discovery is making its last trip to orbit. Its destination is the International Space Station.
Only one other shuttle launch remains on NASA's official schedule, at the end of February. That will end 30 years of shuttle flight unless money is forthcoming for an extra mission.
