From Launch Pad 39B, Space Shuttle Atlantis begins rolling back to the Vehicle Assembly Building. First motion was at 10:04 a.m. EDT. First motion off the pad was at 10:04 a.m. EDT. The rollback is a safety precaution as the area waits for the arrival of Tropical Storm Ernesto. The storm is forecast to be bringing 58-mph to 70-mph winds in the next 24 hours. The shuttle will be moved into high bay 2, on the southwest side of the VAB, for protection from the storm. Photo credit: NASA/Jack Pfaller
