Despite a helium leak in one of space shuttle Discovery's maneuvering rockets, NASA's senior managers late today gave the shuttle a "go" for launch April 5.
Engineers convinced managers the helium leak is not a threat to the crew and Discovery is now cleared to fly to the International Space Station with more experiments, spare parts and supplies.
All that's left now are four shuttle flights by year's end.
NASA plans to wrap up the shuttle program leaving it to rockets and spaceships from Russia, Europe and Japan to supply the station.
