Magnetic Mineralogy in Lunar Mare Basalts and Implications for Paleointensity Retrieval

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Lunar paleomagnetic studies have identified multidomain metallic Fe–Ni alloys as the dominant magnetic contributors in mare basalts. Here, we explore the low‐temperature magnetic behavior of standard samples for a suite of opaque minerals that occur within mare basalts (single‐domain and multidomain Fe, wüstite, ulvöspinel, iron chromite ...

Soil mechanics on the Moon, Mars, and Mulberry [PDF]

open access: yes
From a soil mechanics point of view, the Moon is a relatively simple place. Without any water, organics, or clay minerals, the geotechnical properties of the lunar soil are confined to a fairly limited range.

Practitioners' Perspective on Protecting Freshwater Biota and Habitats at Flood‐Relief Pumps in New Zealand

open access: yesEcological Management &Restoration, Volume 26, Issue 3, September 2025.
ABSTRACT Land drainage infrastructure, including flood‐relief pumps, plays a critical role in protecting life and property, and for maintaining productive land. However, there is increasing recognition of the significant negative effects of flood‐relief pumps on aquatic species and habitats.

Nanophase Fe0 in lunar soils

open access: yesJournal of Earth System Science, 2005
Back scattered electron and transmission electron imaging of lunar soil grains reveal an abundance of submicrometer-sized pure Fe0 globules that occur in the rinds of many soil grains and in the submillimeter sized vesicular glass-cemented grains called agglutinates. Grain rinds are amorphous silicates that were deposited on grains exposed at the lunar

A Study of Lunar Regolith Obtained during the Apollo and Luna Space Programs Based on Principal Component Analysis

open access: yesAerospace
In this study, a modern principal component analysis (PCA) of the chemical properties of lunar soils was conducted. American and Soviet results acquired during the Apollo and Luna missions, respectively, were analyzed and compared.

Energy storage for a lunar base by the reversible chemical reaction: CaO+H2O reversible reaction Ca(OH)2 [PDF]

open access: yes
A thermochemical solar energy storage concept involving the reversible reaction CaO + H2O yields Ca(OH)2 is proposed as a power system element for a lunar base. The operation and components of such a system are described. The CaO/H2O system is capable of
