KENNEDY SPACE CENTER, FLA. - After its overnight rollout on the crawler-transporter from the Vehicle Assembly Building, Space Shuttle Atlantis, on top of the mobile launcher platform, is reflected in the pool of water near Launch Pad 39B. As if waiting with open arms, the rotating service structure is extended outward on the pad. It will later be rotated to enclose the shuttle. The slow speed of the crawler results in a 6- to 8-hour trek to the pad approximately 4 miles away. Atlantis' launch window begins Aug. 27 for an 11-day mission to the International Space Station. The STS-115 crew of six astronauts will continue construction of the station and install their cargo, the Port 3/4 truss segment with its two large solar arrays. Photo credit: NASA/Tony Gray
