Materials International Space Station Experiment, or MISSE, in the grasp of the International Space Station robotic Special Purpose Dexterous Manipulator. Mission Control personnel on Earth used a robotic arm to relocate MISSE from inside the Japanese Experiment Module airlock to its installation locations on the exterior of Space Station. The MISSE space flight experiment is a collaboration among the Air Force Research Laboratory, NASA, Georgia Tech Research Institute and DuPont to study the effects of space weather exposure on spacecraft materials.
