The objective of the Polished Plate Micrometeoroid and Debris (PPMD) experiment is to assess and characterize the natural micrometeoroid and the man-made debris (M&D) environments in the Mir high-inclination orbit. The PPMD experiment will determine the M&D impact fluxes, the mass range of M&D particles encountered, sources of the debris encountered, and characterize the resulting impact damage. The PPMD experiment consists of plates made of gold, aluminum, and zinc. The plates are attached to the Experiment Container mounting plate where they will be exposed to the environment around Mir. An atomic-oxygen pinhole camera is utilized to assist in determining the viewing direction. The PPMD experiment is developed by Langley Research Center. | ||
