STS-135 Update: Weather Delays Rotating Service Structure Rollback

Bad weather that moved into area of NASA’s Kennedy Space Center in Florida has delayed the scheduled rollback of the Rotating Service Structure surrounding space shuttle Atlantis on Launch Pad 39A.

With the scheduled liftoff of Atlantis just one day away, Jeff Spaulding, NASA test director, Joe Delai, STS-135 payload manager, and Kathy Winters, shuttle weather officer, conducted the last countdown status briefing of the Space Shuttle Program this morning.

Winters reported that the launch weather forecast remains unchanged, with a 30 percent chance of favorable weather for the 11:26 a.m. EDT liftoff. The forecast is a more favorable 80 percent when the filling of the huge external fuel tank is set to begin.

“Our teams here and really all around the world have been working extremely hard for quite awhile on this particular mission to make sure the vehicle and the payload are ready for hopefully a magnificent launch on Friday,” said NASA Test Director Jeff Spaulding.

At 5 a.m. this morning, the countdown entered a planned hold at the T-11 hour mark, and will resume at 7:01 p.m. tonight.

The astronauts had an early wakeup call as they continue to prepare for tomorrow’s launch of Atlantis on the STS-135 mission to the International Space Station.
