Regolith-atmosphere exchange of water in Mars' recent past [PDF]

open access: yes, 2017
We investigate the exchange of water vapour between the regolith and atmosphere of Mars, and how it varies with different orbital parameters, atmospheric dust contents and surface water ice reservoirs.

The collisional evolution of undifferentiated asteroids and the formation of chondritic meteoroids [PDF]

open access: yes, 2016
Most meteorites are fragments from recent collisions experienced in the asteroid belt. In such a hyper-velocity collision, the smaller collision partner is destroyed, whereas a crater on the asteroid is formed or it is entirely disrupted, too.

Vapor Deposits in the Lunar Regolith [PDF]

open access: yesScience, 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

Bulk Density of the Lunar Regolith at the Chang'E‐3 Landing Site as Estimated From Lunar Penetrating Radar

open access: yesEarth and Space Science, 2020
Bulk density of the lunar regolith is a key factor affecting its geophysical and geotechnical properties. In this study, a new method for estimating the bulk density of the lunar regolith is developed based on the geometric characteristic (i.e ...

Effect of Target Properties on Regolith Production

open access: yesRemote Sensing
Based on the measurements of regolith thicknesses on the lunar maria (basalts), the lunar regolith was determined to have accumulated at a rate of about 1 m/Gyr since the era of the late heavy bombardment.

Development and properties of a magnetic high-titanium lunar regolith simulant IRSM-1

open access: yesYantu gongcheng xuebao, 2023
The moon exploration has progressed into the stage of in-situ resource utilization (ISRU). Systematically understanding the unique mechanical response and engineering characteristics of the lunar regolith is crucial for the development and exploitation ...

Making parts on Mars: Laser processing of iron contaminated by regolith simulant

open access: yesMaterials Today Advances
Manufacturing pure metals on Mars is challenging due to limited energy resources and unavoidable contamination of raw materials and production equipment with the Martian dust (regolith) resulting in impure materials.

The stratification of regolith on celestial objects

open access: yes, 2015
All atmosphere-less planetary bodies are covered with a dust layer, the so-called regolith, which determines the optical, mechanical and thermal properties of their surface.

Deep dielectric charging of regolith within the Moon\u27s permanently shadowed regions [PDF]

open access: yes, 2014
Energetic charged particles, such as galactic cosmic rays (GCRs) and solar energetic particles (SEPs), can penetrate deep within the lunar surface, resulting in deep dielectric charging.

Structure and Formation Mechanism of Lunar Regolith

open access: yesSpace: Science & Technology
Lunar regolith is a thin layer of weakly cohesive detrital materials covering the lunar surface. Studies on returned lunar samples have revealed that the lunar regolith mainly consists of fragments of rocks, minerals, breccia, glasses, and agglutinates ...
