On Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers use the payload ground-handling mechanism in the Payload Changeout Room, or PCR, to aid the transfer of the Multi-Purpose Logistics Module Leonardo (center) and the Lightweight Multi-Purpose Experiment Support Structure Carrier (bottom) from the payload canister 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
