Vapor Deposits in the Lunar Regolith [PDF]
Science, 1994 Since the Apollo missions, we have emphasized the following points, which are based on theoretical calculations and on laboratory studies of the properties of evaporated silicate deposits and of lunar samples. The mass of vapor generated by impacts on the lunar surface is comparable in magnitude to the mass of impact melt glasses; the physics of impact

Solar wind erosion of lunar regolith is suppressed by surface morphology and regolith properties. [PDF]
Commun Earth EnvironAbstract Important aspects concerning the origin and formation of the Moon’s exosphere, its tenuous gas envelope, remain puzzling with uncertainties regarding the importance of different effects. Two competing processes — micrometeoroid impact vaporization and solar wind ion sputtering — are considered key contributors to the ejection of ...

The viscosity and processing of molten lunar regolith [PDF]
Scientific ReportsEstablishing a permanent, self-sufficient habitat for humans on planetary bodies is critical for successful space exploration. In-situ resource utilisation (ISRU) of locally available resources offers the possibility of an energy-efficient and cost ...

Quaternaire, 2011 Regolith formations are surficial fragmental and unconsolidated rocks whose genesis and properties result from successive periods of surface processes. They comprise: autochthonous formations resulting directly from successive periods of surface weathering in the upper 200 metres of the Earth's crust; allochthonous formations in which the ...

Objective Regolith-Landform Mapping in a Regolith Dominated Terrain to Inform Mineral Exploration [PDF]
Geosciences, 2018 An objective method for generating statistically sound objective regolith-landform maps using widely accessible digital topographic and geophysical data without requiring specific regional knowledge is demonstrated and has application as a first pass ...

Self-Organization Characteristics of Lunar Regolith Inferred by Yutu-2 Lunar Penetrating Radar
Remote Sensing, 2021 Most previous studies tend to simplify the lunar regolith as a homogeneous medium. However, the lunar regolith is not completely homogeneous, because there are weak reflections from the lunar regolith layer.

Cosmogenic nuclide weathering biases: corrections and potential for denudation and weathering rate measurements [PDF]
Geochronology, 2022 Cosmogenic radionuclides (CRNs) are the standard tool to derive centennial-to-millennial timescale denudation rates; however, it has been demonstrated that chemical weathering in some settings can bias CRNs as a proxy for landscape denudation. Currently,
