IMPACT STUDIES ON LUNAR DUST MODELS AT VARIOUS VACUUMS

Abstract

An analysis of factors relevant to lunar environmen al simulation hows that the dynamic behavior of lunar dust models in various vacuums must be studied to establish the degree of vacuum required of a lunar simulator. Various silicicAND BASALTIC ROCK DUSTS WERE SELECTED AS LUNAR DUST MODELS AND TESTED UNDER A RANGE OF VACUUMS. Although crater width measurements indicate lunar dust models do not change their resistance to impact at vacuums, depth of penetration measurements do show a continuous change in resistance. The behavior of lunar dust particles depends upon both particle size distribution and particle microstructure. The effects of hold times at vacuum, container walls, dust shallowness, and the composition of the residual atmosphere on dust behavior are analyzed.
