NASA announced Space Shuttle Atlantis has been cleared for launch on June 8:
Barring technical problems or weather-related delays, the shuttle is scheduled to lift off at 7:38 p.m. EDT (2338 GMT) from the Kennedy Space Center in Florida.
"We're good to go," shuttle program manager Wayne Hale said. "We have no show-stoppers ahead of us," he told a news conference.
NASA had planned to fly its first mission of the year in March, but a hailstorm on February 26 hammered the shuttle, damaging its external fuel tank.
The shuttle was returned to a processing hangar for repairs that stole valuable time from a tight schedule to finish building the space station before shuttles -- which are required for assembly of the orbital outpost -- are retired in 2010
