Coupled Effects of Grain Size and Metallic Iron on Spectral and Polarimetric Properties of Lunar Simulants

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The lunar surface is heterogeneous in grain size and metallic iron abundance due to diverse histories of space weathering. The spectral and polarimetric properties of the lunar regolith are strongly affected by both grain size and metallic iron particles.

Morphological and Spectral Characterization of Lunar Regolith Breakdown due to Water Ice

The Planetary Science Journal
Remote 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.

Rheology and Structure of Fe‐Mg‐Ca Enriched Silicate Melt: Benchmarking Viscosity Models for an Exotic Planetary Composition

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Silicate melt viscosity plays a pivotal role in the evolution of rocky bodies within the Solar System, exerting first‐order control on mantle differentiation and stratification, while dictating the metal‐silicate separation and the subsequent volcanic activity.

Spark Plasma Sintering and Optical Characterization of Lunar Regolith Simulant

Acta Astronautica, 2022
Regolith-covered surfaces exist in several planetological environments, including the Moon, Mars, NEAs, etc, some of which have been identified as first targets for future colonization outposts. Clearly, the development of advanced technologies in the framework of ISRU concept is a key asset to boost human space explorations on these celestial bodies ...

Formation of Compact Aggregate Piles on a Surface Through Dissipation of Kinetic Energy Associated With Horizontal Motion

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Accumulation of dust on the Lunar and Martian surfaces plays a critical role in both surface evolution and human exploration efforts, limiting equipment lifetimes and obscuring optical surfaces. Yet, the underlying physics of surface soiling is still poorly understood.

New High Precision Measurements of Apollo Samples: 0.3–5 GHz Complex Refractive Indices

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Active and passive radar techniques provide information on the subsurface structure and history of planetary bodies. However, interpretations of radar data are limited by our understanding of the complex dielectric permittivity and magnetic permeability of the surface material.

Verification of a virtual lunar regolith simulant

Frontiers in Space Technologies
Introduction: Physical regolith simulants are valuable tools for developing In-Situ Resource Utilisation hardware. However, using virtual models of regolith instead can reduce costs, limit exposure to hazardous materials, and offer a practical method of testing the effects of reduced gravity.Methods: We verify a virtual model of regolith as ...
