Thermal properties of processed lunar regolith simulant [PDF]

International Journal of Applied Ceramic Technology, 2019
AbstractIn this paper, the thermal characterization of lunar regolith simulant, sintered using a conventional oven under ambient and vacuum conditions is presented. Additionally, thermal characterization of samples is performed for the parts manufactured using solar, laser, and microwave processing.

Influence of the Earthward and Tailward Ion Flows on the Lunar Surface Water in the Magnetotail

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Earth wind, namely the particles from the Earth's magnetotail, is an important source of lunar water. Besides tailward flow incident on the lunar nearside when the Moon is in the magnetotail, there exists earthward flow bombarding the farside, affecting the distribution and preservation of lunar water.

Development and Validation of a Model for Hydrogen Reduction of JSC-1A [PDF]

Hydrogen reduction of lunar regolith has been proposed as a viable technology for oxygen production on the moon. Hydrogen reduces FeO present in the lunar regolith to form metallic iron and water. The water may be electrolyzed to recycle the hydrogen and

Microcratering within the lunar regolith — a theory and observation [PDF]

Scanning, 2000
AbstractSince the Apollo 11 mission to the moon, there has been substantial analysis of the lunar rocks and soil grains, utilizing more recent advances in electron probe technologies. It is the objective of this research to revisit the theories concerning the microcratering within the lunar regolith.

Space-weathered rims on lunar ilmenite as an indicator for relative exposure ages of regolith

Communications Earth & Environment
Solar wind irradiation, as a crucial space weathering mechanism, alters the microscopic characteristics and reflectance spectrum of the lunar regolith, and its cumulative effect is strongly related to the exposure time.

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Methods for Cleaning Apollo Passive Seismic Data

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Apollo passive seismic data provide a unique resource for studying the lunar interior structure. However, the raw data are frequently contaminated by various artifacts, either related to the seismic sensors and the acquisition system or to issues during data transmission to the Earth.

Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith

The Planetary Science Journal
Lunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons.
