As the sun goes down behind Launch Pad 39A at NASA's Kennedy Space Center in Florida.

As the sun goes down behind Launch Pad 39A at NASA's Kennedy Space Center in Florida, the rotating service structure moves away from space shuttle Atlantis. Liftoff on its STS-129 mission is set for 2:28 p.m. EST Nov. 16. The movable structure, which provides weather protection and access for technicians to work on the shuttle, began being retracted at 5:20 p.m. EST and was in the park position by 5:56 p.m.

STS-129 crew members are Commander Charles O. Hobaugh; Pilot Barry E. Wilmore; and Mission Specialists Leland Melvin, Randy Bresnik, Mike Foreman and Robert L. Satcher Jr. On the STS-129 mission to the International Space Station, the crew will deliver two spare gyroscopes, two nitrogen tank assemblies, two pump modules, an ammonia tank assembly and a spare latching end effector for the station's robotic arm. Atlantis will return to Earth a station crew member, Nicole Stott, who has spent more than two months aboard the orbiting laboratory. STS-129 is slated to be the final space shuttle Expedition crew rotation flight.
