In the Payload Changeout Room, or PCR, on Launch Pad 39A at NASA's Kennedy Space Center in Florida, space shuttle Endeavour's STS-126 mission payload is transferred from the payload canister into the PCR. Seen here is the Multi-Purpose Logistics Module Leonardo. The payload later will be installed in Endeavour's payload bay. Endeavour is targeted for launch on Nov. 14. Photo credit: NASA/Kim Shiflett
