CAPE CANAVERAL, Fla. - NASA has finally settled on a Wednesday night launch for space shuttle Discovery.
The flight to the International Space Station was originally set for in mid-February.
It was delayed four times because of concern over shuttle valves.
But senior NASA managers meeting at Kennedy Space Center in Florida have put the valve issue to rest for Discovery and cleared the shuttle for flight.
Managers had ordered extensive testing of the hydrogen gas valves after one broke during the last shuttle launch.
Liftoff next Wednesday will be at 9:20 p.m.
Seven astronauts will ride Discovery into orbit, taking with them one final set of solar wings for the space station.
