Space shuttle Atlantis sits on Launch Pad 39A for STS-125 after rollout from the Vehicle Assembly Building. The shuttle sits atop the mobile launcher platform, which is carried by the crawler-transporter beneath.
At left is the rotating service structure with the payload changeout room that allows transfer of payloads from a canister into the shuttle's payload bay. Next to the shuttle is the fixed service structure with its 80-foot lightning mast on top.
