Compressibility of Simulated Lunar Soils in Air and in Ultrahigh Vacuum
Abstract
A simulated lunar soil of comminuted tholeiitic basalt powder with particles less than 60 microns in size was tested in one dimensional compression to determine the effect of the initial void ratio and the ambient pressure on the compressibility of the soil. The initial void ratio ranged from 1.12 to 2.00 and the ambient pressure was restricted to three levels; atmospheric pressure, 10 to the minus 8th power Torr, and 10 to the minus 10th power Torr. The results of the tests indicate that the compressibility of the powders increased as the initial void ratio increased. Also the powders tended to become less compressible as the ambient pressure decreased.
