Morphological and Spectral Characterization of Lunar Regolith Breakdown due to Water Ice
The Planetary Science JournalRemote sensing observations of the Moon suggest that the lunar polar regolith environment is affected by several natural processes that may cause the regolith in these regions to become more porous and fine particulate.

Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith
The Planetary Science JournalLunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons.

Trends in regolith thickness in a headwater catchment, Sierra Nevada, California
Vadose Zone Journal, 2023 Rooting in deep regolith enables forests to withstand seasonal and annual precipitation shortfalls. Despite its ecological importance, spatial patterns in regolith thickness within forest ecosystems are scarcely documented.

Global Regolith Thermophysical Properties of the Moon From the Diviner Lunar Radiometer Experiment [PDF]
, 2017 We used infrared data from the Lunar Reconnaissance Orbiter (LRO) Diviner Lunar Radiometer Experiment to globally map thermophysical properties of the Moon's regolith fines layer.

Selection of temperature and power parameters for multi-modular lunar jet penetrator [PDF]
INCAS Bulletin, 2019 The questions and the particularity of the choice of design parameters of multi-module lunar jet penetrators are considered. A constructive layout of the penetrator is proposed and the advantages of a multi-modular design are presented.

Scattering And Absorption of Light in Planetary Regoliths [PDF]
Journal of Visualized Experiments, 2019 Theoretical, numerical, and experimental methods are presented for multiple scattering of light in macroscopic discrete random media of densely-packed microscopic particles. The theoretical and numerical methods constitute a framework of Radiative Transfer with Reciprocal Transactions (R2T2).

Volatiles in the Martian regolith
Geophysical Research Letters, 1979 An inventory of released volatiles on Mars has been derived based upon Viking measurements of atmospheric and surface chemical compositionand upon the inferred mineralogy of a ubiquitous regolithassumed to average 200m in depth. This model is consistent with the relative abundances of volatiles (except for S) on the Earth's surfacebut implies one ...

The CM carbonaceous chondrite regolith Diepenveen [PDF]
Meteoritics & Planetary Science, 2019 AbstractA carbonaceous chondrite was recovered immediately after the fall near the village of Diepenveen in the Netherlands on October 27, 1873, but came to light only in 2012. Analysis of sodium and poly‐aromatic hydrocarbon content suggests little contamination from handling.
