A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...

Simplified Particle Models and Properties Analysis Designed for DEM Lunar Soil Simulants

Aerospace
The discrete element method (DEM) is one of the most popular methods for simulating lunar soil simulants due to the lack of real lunar soil. To reduce the computational consumption and difficulty because of complex particle models, simplified particle ...

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.

Collection and In Situ Analyses of Regolith Samples by the Mars 2020 Rover: Implications for Their Formation and Alteration History

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract The Perseverance rover has sampled mm‐size lithic fragments containing olivine likely from at least two source regions from the surface of an inactive megaripple surface, and fine‐grained material from the surface and to a depth of ∼4–6 cm. Some of the mm‐size grains lack a coherent diffraction pattern measured by PIXL, consistent with the ...
