densityaverage minimum density of LMS-1 is higher than that of lunar mare regolith, but the bulk and maximum density data collected from returned mare samples lie within confidence of the1 source for this simulantGeomechanical properties of lunar regolith simulants LHS-1 and LMS-1

densityless dense packing arrangements of LHS-1 were not as sensitive to slight disturbances from handling during experiments as LMS-1, attributed to the high anorthosite content1 source for this simulantGeomechanical properties of lunar regolith simulants LHS-1 and LMS-1

densityDuring experiments, it was noted that LMS-1 takes less mechanical agitation to reach a higher relative density compared to LHS-1, so slight disturbances to the sample during1 source for this simulantGeomechanical properties of lunar regolith simulants LHS-1 and LMS-1
