When was the space shuttle Discovery to to launch?
Running four days late, the shuttle Discovery was refueled for launch late Friday for a 13-day mission to deliver more than 7.5 tons of supplies and equipment to the International Space Station. With forecasters predicting a 60 percent chance of good weather, Discovery was scheduled for liftoff at 11:59 p.m. EDT. An 8-inch liquid hydrogen valve blamed for back-to-back launch delays earlier this week worked normally during fueling Friday and engineers did not have to exercise a waiver that would have permitted additional troubleshooting.
