Space shuttle Discovery needs more repair work before it can take off on its last flight.

NASA said Wednesday it will empty Discovery's on-board fuel tanks, then replace two seals in a line that had been leaking. The job at the launch pad will take the rest of this week. If all goes well, the shuttle will remain on track for a Nov. 1 liftoff to the International Space Station.

Technicians checked bolts on the leaky fuel line earlier this week. The bolts were tight. But for whatever reason, the leak stopped, after a week of slow seepage. Managers ordered the seal replacements as a precaution.

The fuel is used to move Discovery around in orbit.
