After rolling out of the Orbiter Processing Facility bay 1 at NASA's Kennedy Space Center, space shuttle Atlantis rolls to the Vehicle Assembly Building. In the VAB, Atlantis will be attached to its external fuel tank and twin solid rocket boosters. After additional preparations are made, the shuttle will be rolled out to Launch Pad 39A to prepare for launch on the STS-125 mission targeted for Oct. 8. Photo credit: NASA/Jack Pfaller
