Endeavour Rollout Stalled By Stormy Forecast

Shuttle Endeavour's planned rollout to Kennedy Space Center launch pad 39A tonight is being postponed 24 hours because a squall line is expected to bring lightning and possibly hail into the area overnight.

Endeavour and six astronauts remain scheduled for launch April 19. A call to stations for rollout is slated for 4 p.m. Thursday, but the operation will be scrubbed again if stormy weather is still in the forecast.

Led by commander Mark Kelly, the Endeavour crew had planned to be at KSC for the rollout. A media Q & A with the crew that had been slated for 8 p.m. also has been scrubbed.

Kelly and his crew will haul a large particle physics experiment up to the International Space Station. The STS-134 mission is one of only two shuttle flights scheduled before fleet retirement. The last flight aboard Atlantis is slated to launch June 28.
