The Long Duration Exposure Facility (LDEF), after nearly six years orbiting Earth, is retrieved during space shuttle mission STS-32. LDEF gathered data about how high-performance spacecraft materials withstand long-term exposure to solar radiation, space debris, and the extreme temperatures of Low Earth Orbit. This information helped engineers select the best materials to build the International Space Station, Mars rovers, and other spacecraft. Credit: NASA
This Month in NASA History: Recovering LDEF
