8/29/2006-The Space Shuttle Atlantis on the giant crawler approaches Pad 39A as it returns to Launch Pad 39B, after reversing course about 2:45 PM (EDT), Tuesday. It had been en route to the Vehicle Assembly Building since early today. There it was to be sheltered from Tropical Storm Ernesto, which as of early this afternoon is expected to skirt far enough west of the Kennedy Space Center to no longer be a threat to the shuttle on the launch pad.
