In the Orbiter Processing Facility, the second of two Materials International Space Station Experiments, or MISSE, is lowered into space shuttle Endeavour's payload bay for installation. The MISSE is part of the payload onboard Endeavour for mission STS-123. The MISSE project is a NASA/Langley Research Center-managed cooperative endeavor to fly materials and other types of space exposure experiments on the International Space Station. The objective is to develop early, low-cost, non-intrusive opportunities to conduct critical space exposure tests of space materials and components planned for use on future spacecraft.
