WRIGHT-PATTERSON AIR FORCE BASE - AF experiments to return home with Discovery

WRIGHT-PATTERSON AIR FORCE BASE, Ohio—Air Force and NASA integrators attach experiment material samples to a passive experiment container that has been bolted to the International Space Station since 2001. Air Force Research Laboratory scientists here are studying materials as part of the Materials on the International Space Station Experiment. The Discovery shuttle crew will remove the carriers and return them to Earth as part of their return-to-flight mission which launched July 26. (U.S. Air Force photo)
