In preparation for lifting Atlantis into high bay 3 of the Vehicle Assembly Building, workers are installing a large crane around it to raise it off the transporter into a vertical position. After Atlantis is lifted and moved into the high bay, the orbiter will be lowered and mated with the external tank and solid rocket boosters already stacked on the mobile launcher platform. Atlantis' launch window begins Aug. 28. During its 11-day mission to the International Space Station, the STS-115 crew of six astronauts will install the Port 3/4 truss segment with its two large solar arrays.
