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.

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.

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

Aerospace
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.

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

A Novel Self‐Supervised Deep Learning Inversion Method Incorporating a Fast Forward Network for Transient Electromagnetic Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Deep learning (DL) is an increasingly popular method for inverting the transient electromagnetic (TEM) data. Currently, DL‐based inversion for TEM data primarily employs supervised learning methods that rely on labeled data sets to train the network.

Diatom-driven activation of in-situ lunar resource utilization for space farming

Biogeotechnics
In this study, we demonstrate that diatoms, through their bioweathering process, can enhance the properties of lunar soil, thereby facilitating the cultivation of crops.
