The sun creeps over the horizon (right) as Space Shuttle Atlantis, atop the Mobile Launcher Platform and Crawler-Transporter, arrives at Launch Pad 39B for preparations before launch. It started its 8-hour rollout from the Vehicle Assembly Building high bay 2 (Safe Haven) at 11:20 p.m., Aug. 13. At left is the Rotating Service Structure in its open position. Towering above the RSS (and attached to the Fixed Service Structure) is the 80-foot tall lightning mast. At right is the 290-foot high water tank that holds 300,000 gallons of water. It is part of the sound suppression system at the pad. Atlantis is scheduled for launch Sept. 8 at 8:31 a.m. EDT on mission STS-106.
