The charge state of electrostatically transported dust on regolith surfaces

Geophysical Research Letters, 2017
The charge state of dust particles on regolith surfaces exposed to ultraviolet radiation or plasma is investigated for understanding the role of electrostatic dust transport in the surface evolution of airless planetary bodies.

Analysis of lunar regolith thermal energy storage [PDF]

The concept of using lunar regolith as a thermal energy storage medium was evaluated. The concept was examined by mathematically modeling the absorption and transfer of heat by the lunar regolith. Regolith thermal and physical properties were established

Using Venus, Earth, and Mars to Understand Exoplanet Volatile and Climate Evolution

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Venus, Earth, and Mars exhibit a wide range of interactions between their deep interiors, surfaces, lower and upper atmospheres, and the Sun, with commensurate variations in the nature of their atmospheres and evolution of their volatiles. By examining these worlds' characteristics and behavior, we can gain some understanding of the breadth of

Determination of the Dynamic Angle of Repose of Lunar Regolith Simulants

Geosciences
The determination of the dynamic angle of repose (DAR) of lunar regolith simulants is essential for modeling material behavior during in situ resource utilization (ISRU) processes and lunar surface operations.

Soil hydraulic properties, mineralogical alteration and pore formation in Regosols from southern Brazil [PDF]

Revista Brasileira de Ciência do Solo
Regosols (Neossolos) are soils with use limitations mainly related to effective depth, abundant presence of rock and saprolite fragments, and frequently high slope gradients; besides that, they represent a new agricultural frontier for grain production ...

Mineralogically Diverse and Salt‐Rich Regolith in Jezero Crater Characterized Using X‐Ray Spectroscopy

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Planetary Instrument for X‐ray Lithochemistry (PIXL) onboard the Perseverance rover has characterized the composition of Martian regolith at a scale of hundreds of microns using micro‐focus X‐ray fluorescence spectroscopy. PIXL data reveal a diverse population of regolith grains with distinct spectral, chemical, and crystallographic ...

Estimation of energy and material use of sintering-based construction for a lunar outpost - with the example of SinterHab module design [PDF]

, 2015
In this paper, we would revisit the usability of microwave for lunar regolith sintering through an in-depth experiment, and examine the minimum materials and energy required for sintering based on the SinterHab design.

Electrostatic Charging of Lunar Cavities Governed by the Flow‐to‐Thermal Speed Ratio: 3D PIC Simulations and a Free‐Fall Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We use Particle‐In‐Cell (PIC) simulations to investigate the charging characteristics inside deep cavities on the lunar surface under the solar wind plasma conditions. Specifically, we systematically study the dependence of the cavity bottom potential on plasma flow velocity and cavity aspect ratio.
