The Express Logistics Carrier-2 moves across the ceiling toward a transportation canister.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the Express Logistics Carrier-2, or ELC-2, moves across the ceiling, past the Tranquility module with the cupola attached, toward a transportation canister in which it will be secured for its trip to Launch Pad 39A. Once at the pad, it will be installed in space shuttle Atlantis' payload bay.

The carrier is part of the payload for Atlantis' STS-129 mission to the International Space Station. The STS-129 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. Launch is targeted for Nov. 16. For information on the STS-129 mission objectives and crew, visit http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts129/index.html.
