A transporter moves the canister containing the payload for space shuttle from the Space Station Processing Facility to Launch Pad 39A.

At NASA's Kennedy Space Center in Florida, a transporter moves the canister containing the payload for space shuttle Atlantis' STS-129 mission to the International Space Station - Express Logistics Carriers 1 and 2 - from the Space Station Processing Facility to Launch Pad 39A. Once at the pad, the payload will be transferred into the Payload Changeout Room for installation in Atlantis' payload bay.

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 set 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.
