Vapor Deposits in the Lunar Regolith [PDF]

open access: bronzeScience, 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

Regolith map of France [PDF]

open access: bronzeQuaternaire, 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 ...

Soil fertility interactions with Sinorhizobium-legume symbiosis in a simulated Martian regolith; effects on nitrogen content and plant health.

open access: yesPLoS ONE, 2021
Due to increasing population growth and declining arable land on Earth, astroagriculture will be vital to terraform Martian regolith for settlement. Nodulating plants and their N-fixing symbionts may play a role in increasing Martian soil fertility.

The viscosity and processing of molten lunar regolith [PDF]

open access: yesScientific Reports
Establishing 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 ...

Objective Regolith-Landform Mapping in a Regolith Dominated Terrain to Inform Mineral Exploration [PDF]

open access: yesGeosciences, 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 ...

Dielectric properties and stratigraphy of regolith in the lunar South Pole-Aitken basin: Observations from the Lunar Penetrating Radar [PDF]

open access: yesAstronomy & Astrophysics, 2022
We examine data obtained by the Lunar Penetrating Radar (LPR) onboard the Chang'E-4 (CE-4) mission to study the dielectric properties and stratigraphy of lunar regolith on the far side of the Moon.

The Dielectric Properties of Martian Regolith at the Tianwen‐1 Landing Site

open access: yesGeophysical Research Letters, 2023
Mars' surface is characterized by a weathered layer of regolith and exposed rock exposures that are the results of long‐term geological processes. The Mars Rover Penetrating Radar (RoPeR) on board the Zhurong rover of China's first Mars mission (Tianwen ...

Regolith of the Crater Floor Units, Jezero Crater, Mars: Textures, Composition, and Implications for Provenance

open access: yesJournal of Geophysical Research: Planets, 2023
A multi‐instrument study of the regolith of Jezero crater floor units by the Perseverance rover has identified three types of regolith: fine‐grained, coarse‐grained, and mixed‐type. Mastcam‐Z, Wide Angle Topographic Sensor for Operations and eNgineering,
