Lunar Impacts

    Mission statement: Use Earth-based observations of the dark portion of the moon to establish the rates and sizes of large meteoroids (greater than 500 grams or 1 pound in mass) striking the lunar surface.

    Why it is important: U.S. Space Exploration Policy eventually calls for extended astronaut stays on the lunar surface. Spacecraft, vehicles, habitats, and EVA suits must all be designed to withstand the stresses posed by the harsh lunar environment over this period of time. Meteoroids, and the ejecta produced when they create impact craters, are part of this environment.
