In the transfer aisle of the Vehicle Assembly Building, workers adjust the sling attachment on the orbiter Atlantis. The orbiter will be lifted up into high bay 1 and lowered onto the mobile launcher platform where the external tank and solid rocket boosters are already stacked. Space Shuttle Atlantis is targeted to roll out to Launch Pad 39A on February 14 for mission STS-117. The mission is No. 21 to the International Space Station and construction flight 13A.
