In the Orbiter Processing Facility at NASA's Kennedy Space Center in Florida, astronauts Tom Marshburn and Julie Payette put on their safety harnesses before taking a close look at space shuttle Endeavour. Both are mission specialists on the STS-127 mission to the International Space Station. The crew members are at Kennedy for a crew equipment interface test, which provides hands-on training and observation of shuttle and flight hardware. Endeavour will deliver the Japanese Experiment Module's Experiment Logistics Module-Exposed Section, or ELM-ES, to the space station on STS-127. Launch is targeted for mid-June, 2009.
