A canister, carrying the Alpha Magnetic Spectrometer-2 (AMS) and Express Logistics Carrier-3 for space shuttle Endeavour's STS-134 mission, moves past the Vehicle Assembly Building on its journey from the Canister Rotation Facility to Launch Pad 39A at NASA's Kennedy Space Center in Florida. At the pad, crews will move the payload into the Payload Ground Handling Mechanism (PGHM), and the rotating service structure (RSS) that protects the shuttle from the elements and provides access to its components will be rotated back into place. The payload is scheduled to be installed into the shuttle's cargo bay March 25.
Endeavour and its six-member STS-134 crew are targeted to lift off April 19 at 7:48 p.m. EDT to deliver the payload to the International Space Station. This is Endeavour's final scheduled mission.
