Space shuttle Discovery has new seals and is no longer leaking. It also has an official launch date.

NASA's senior managers met Monday and set Discovery's last liftoff for next Monday. Launch time is 4:40 p.m.

This will be Discovery's 39th and final mission as NASA retires its three remaining shuttles. The White House wants NASA to focus on developing spaceships that can take astronauts out of orbit and into deep space.

Over the weekend, technicians replaced a pair of seals in a fuel line aboard Discovery that had been leaking. NASA says the repairs apparently solved the problem.

Discovery will deliver equipment to the International Space Station.
