Abstract : The National Aeronautics and Space Administration I Strategic Defence Initiative Organization Space Environmental Effects on Materials Workshop, June 1988, identified and prioritized candidate materials spaceflight experiments needed to validate long-term performance of materials on future spacecraft (reference 1). Working groups considered six environmental factors which may have significant effects on spacecraft materials: atomic oxygen, solar radiation, trapped radiation, micrometeoroids and debris, contamination, and spacecraft charging. Although most of the priorities of each group were parochial to its specific discipline, the highest priority identified by all participants of that workshop was virtually unanimous: The return of the NASA Long Duration Exposure Facility safely to earth, followed by a detailed analysis of its materials to compare with data obtained in previous relatively short in-space exposures and to validate.
