The Lunar Regolith

Regolith is a terrestrial term, also used for the Moon. It has been defined as " a general term for the layer or mantle of fragmental and unconsolidated rock material, whether residual or transported and of highly varied character, that nearly everywhere forms the surface of the land and overlies or covers bedrock. It includes rock debris of all kinds, [including] volcanic ash. .. " (Bates and ...

Evaluations of lunar regolith simulants

Apollo lunar regolith samples are not available in quantity for engineering studies with In-Situ Resource Utilization (ISRU). Therefore, with expectation of a return to the Moon, dozens of regolith (soil) simulants have been developed, to some extent a result of inefficient distribution of NASA-sanctioned simulants. In this paper, we review many of these simulants, with evaluations of their sho...

Development of Standardized Lunar Regolith Simulant Materials

Isotopic variability of nitrogen in lunar regolith.

Hashizume et al. (1) claim that the distribution and isotopic composition of nitrogen in the lunar regolith can be explained by a two-component mixing model. Their report, however, fails to discuss the bulk of existing relevant data— data that show unequivocally that the conclusions in (1) cannot be correct. Although the data, derived by several different groups on many different samples using ...
