From inside the Payload Changeout Room on Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers oversee the opening of the doors of the payload canister. The canister contains space shuttle Endeavour's STS-126 mission payload, the Multi-Purpose Logistics Module Leonardo and the Lightweight Multi-Purpose Experiment Support Structure Carrier. The payload will be moved into the PCR. Later, the payload will be installed in Endeavour's payload bay. Endeavour is targeted for launch on Nov. 14. Photo credit: NASA/Dimitri Gerondidakis
