Viewed from above, space shuttle Atlantis arrives in the Vehicle Assembly Building's high bay 3 at NASA's Kennedy Space Center in Florida after rolling back from Launch Pad 39A. In the VAB, Atlantis will await launch on its STS-125 mission to repair NASA's Hubble Space Telescope. First motion of Atlantis off the pad was at 6:48 a.m. EDT. The journey was expected to take about six hours. Atlantis' targeted launch on Oct. 14 was delayed when a system that transfers science data from the orbiting observatory to Earth malfunctioned on Sept. 27. The new target launch date is under review. Photo credit: NASA/Kim Shiflett
