Testing the Fidelity of Paleopole Determinations From Multidirectionally Magnetized Lunar Crustal Anomaly Source Bodies

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Inversions of satellite observations of the lunar crustal magnetic field do not consistently produce regional magnetization directions consistent with a selenocentric axial dipolar field. We modeled the thermal evolution of anomaly source bodies in the lunar crust and found that large features (impact melt sheets and ejecta deposits) cool ...

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.

Mineralogical sources of groundwater fluoride in Archaen bedrock/regolith aquifers: Mass balances from southern India and north-central Sri Lanka

Journal of Hydrology: Regional Studies, 2015
Study region: The Maheshwaram and Waipally catchments of Andhra Pradesh, India, and the Plonnaruwa catchment of north-central Sri Lanka. Study focus: The distribution of F across eight crystalline phases and between the bedrock and the regolith at eleven

Origins of the Water Ice Excavated by the Christmas Eve Crater Formation on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract On the 24th of December 2021, a meteoroid struck the martian surface, producing a 150‐m wide crater and excavating the lowest‐latitude water ice observed on Mars to date. Knowledge of the preimpact depth, thickness and lateral continuity of the excavated ice would provide new insight into past environmental changes such as temperature and ...

Northwest Africa 16788: The Largest Known Individual Martian Meteorite—A New Olivine Microgabbroic Shergottite and Its Implications for Martian Magmatism

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We present a comprehensive study of a new Martian meteorite, Northwest Africa (NWA) 16788, found in the Sahara Desert in July 2023. This specimen constitutes the largest known individual meteorite of Martian origin, with a total weight of ⁓25 kg. A detailed mineralogical and geochemical investigation identifies NWA 16788 as an enriched olivine

Parameter Estimation of Lunar Regolith from Lunar Penetrating Radar Data

Sensors, 2018
Parameter estimation of the lunar regolith not only provides important information about the composition but is also critical to quantifying potential resources for lunar exploration and engineering for human outposts.

Global Effects of Magnetic Anomalies on the Near‐Surface Lunar Plasma Environment

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The interaction between lunar magnetic anomalies and the solar wind plasma creates unique structures known as “lunar mini‐magnetospheres,” which reflect and partially shield the lunar surface from impinging solar wind protons. Using data from the Sub‐KeV Atom Reflecting Analyzer onboard Chandrayaan‐1, we produce new surface maps of energetic ...

Magnetic Mineralogy in Lunar Mare Basalts and Implications for Paleointensity Retrieval

Journal 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 ...
