The gravity stabilization feature of the NASA Long Duration Exposure Facility (LDEF), which was recovered in January 1990 after 5.7 years of continuous exposure to the LEO environment, has allowed the resolution of the flux and trajectories of impacting meteoroids and space-debris particulates. Attention is presently given to the stereoscopic video imaging results obtained for the large impact features on the LDEF's aluminum frame. Extreme directionalities appear to typify impacting particulates larger than 0.1 mm in diameter; this is not explainable in light of current models. Recommendations for further LDEF analyses to ensure the safe design of future spacecraft are presented.
