On Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers ensure smooth closure of space shuttle Endeavour's payload bay doors. Elements stored in the payload bay are, at bottom, the Integrated Cargo Carrier-Vertical Light Deploy (with the Space-to-Ground Antenna showing), the Experiment Logistics Module-Exposed Section (middle) and the Japanese Experiment Module's Exposed Facility (at top). The STS-127 mission is the final of three flights dedicated to the assembly of the Japanese Kibo laboratory complex on the International Space Station. Photo credit: NASA/Jack Pfaller
