Previous researches have revealed that the lunar surface soil (regolith) has a very wide range of grain size distribution (e.g. Heiken et al. 1991). The mechanical properties of such a granular material may be quite different from those of poorly-graded granular materials. This paper proposes...
Disintegration and vaporization on impact comminute the native material, but also melt, and hence aggregate, some rock and soil in the form of glasses. Apparently, the competing processes of comminution and aggregation achieve a steady-state grain-size distribution in spite of variations in the ...

Lunar soil (regolith) simulant JSC–1 has been widely used by a variety of investigators. Standard laboratory measurements were conducted to characterize the tensile strengths, grain size distribution and other basic behavior. Direct tension experiments were conducted on JSC–1 to determine its tensile...

This variation in thickness was expected due to the grain size distribution of lunar regolith, with grains up to 1 mm. Open pores, up to 0.60 mm large, revealed the poor bonding between the layers. As for the closed porosity, up to 0.45 mm large, it highlights the high volume...
(expressed as FeO, written as Is/FeO) is a good measure of maturity of a lunar soil (Heiken et al.1991). Among the samples examined, Is/FeO was only measured for the Apollo samples: 78 and 80 for Apollo 11 (10,084) and Apollo 16 (60,501) samples, respectively, indicating that ...
Physical particle characteristics such as grain size distribution and sphericity are strongly linked to soil compaction, cohesion and shear strength, which makes it hard to evaluate these properties as separate values19,22,39. It is however an important consideration for lunar exploration. At shallow ...
