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

Materials 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.

Ground-penetrating radar investigation of regolith thickness on a periglacial alpine summit flat, Uinta Mountains, Utah, USA

Arctic, Antarctic, and Alpine Research
Summit flats are low-relief, gently sloping landforms common in periglacial mountain environments. Apart from at their edges where summit flats are truncated by glacial headwalls and at their crests where isolated tors are occasionally present, bedrock ...

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.

Radiation Exposure and Shielding Effects on the Lunar Surface

Space Weather
The Moon will be a primary target for human space exploration in the near future. A limiting factor for a crewed mission to the Moon is the radiation dose during their stay on the lunar surface.

Site Specific Ground Response Analysis for Quantifying Site Amplification at A Regolith Site

Indonesian Journal on Geoscience, 2017
DOI: 10.17014/ijog.4.3.159-167A numerical model has demonstrated that it can simulate reasonably well earthquake motions at the ground level during a seismic event. The most widely used model is an equivalent linear approach.

Investigation of the melting behavior of laser-melted lunar regolith simulant for in-situ construction

Journal of Materials Research and Technology
Additive manufacturing of lunar regolith is one of the most promising methods for lunar surface construction. In order to obtain excellent formability of lunar regolith, the interaction between laser and lunar regolith has to be studied in detail.

Solar Wind Implantation Into the Lunar Regolith: Monte Carlo Simulations of H Retention in a Surface With Defects and the H2 Exosphere

Journal of Geophysical Research: Planets, 2019
The solar wind implants protons into the top 20–30 nm of lunar regolith grains, and the implanted hydrogen will diffuse out of the regolith but also interact with oxygen in the regolith oxides. We apply a statistical approach to estimate the diffusion of
