It is generally believed that the top centimeters of mature lunar regolith should be dominated by fine particles that contain few rocky fragments, but surface fragments are occasionally visible in mature lunar regolith.

Properties and Mechanics of the Lunar Regolith
Applied Mechanics Reviews, 1993Knowledge of the lunar regolith is essential to success in lunar missions whether crewed or robotic. The regolith is the loose material overlying more intact strata on the Moon. It varies in thickness from several meters on the maria or lunar seas to many meters on the highlands of the Moon.

Investigation into Uses for Lunar Regolith
AIP Conference Proceedings, 2003Any sustained effort on the Moon will require use of in‐situ resources as much as possible to reduce costs. Power generation is a primary concern and solar cells would be a convenient source of power for any lunar activity. Lunar regolith is an easily accessible in‐situ resource.

On the depth of the lunar regolith
The Moon, 1970The aim of this paper is to point out that if the sinuous rilles on the Moon represent trenches in the mare ground in which they meander, the existence of a great number of individual boulders on their slopes - as discovered on the high-resolution photographs taken by US Lunar Orbiters 4 and 5 in 1967 - suggests that the solid substrate of the lunar ...

Robotic drilling tests in simulated lunar regolith environment
J. Field Robotics, 2021A deep extraterrestrial drilling mission potentially adds a new level of complexity, and it is crucial to understand the associated challenges. To cope with China's Chang'E 5 mission to return subsurface regolith samples from the Moon, a series of ...

2012
In the year 2004 NASA declared its mission to prepare for a return of man to the moon as early as 2015 but no later than 2020, while continuing with robotic missions to Mars (NASA 2004). As a long-term goal, it was intended to establish permanent human presence on the moon and eventually send human missions to Mars.

Discovery of Vapor Deposits in the Lunar Regolith
Science, 1993Lunar soils contain micrometer-sized mineral grains surrounded by thin amorphous rims. Similar features have been produced by exposure of pristine grains to a simulated solar wind, leading to the widespread belief that the amorphous rims result from radiation damage. Electron microscopy studies show, however, that the amorphous rims are compositionally

Noble gases in the lunar regolith
Chinese Journal of Geochemistry, 2003The most fundamental character of lunar soil is its high concentrations of solar-wind-implanted elements, and the concentrations and behavior of the noble gases He, Ne, Ar, and Xe, which provide unique and extensive information about a broad range of fundamental problems.

Electron Microscopy in the Study of Lunar Regolith
Crystallography Reports, 2021The results of long-term mineralogical studies of the lunar regolith, obtained using analytical scanning and transmission electron microscopy, are presented. These studies revealed 105 mineral phases new for the Moon, 43 of which were discovered for the first time under natural conditions; an electronic link to the final table is given.

Isotopic Variability of Nitrogen in Lunar Regolith
Science, 2001Hashizume et al . ([1][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 ...
