Mineralogically Diverse and Salt‐Rich Regolith in Jezero Crater Characterized Using X‐Ray Spectroscopy

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Planetary Instrument for X‐ray Lithochemistry (PIXL) onboard the Perseverance rover has characterized the composition of Martian regolith at a scale of hundreds of microns using micro‐focus X‐ray fluorescence spectroscopy. PIXL data reveal a diverse population of regolith grains with distinct spectral, chemical, and crystallographic ...

Electrostatic Charging of Lunar Cavities Governed by the Flow‐to‐Thermal Speed Ratio: 3D PIC Simulations and a Free‐Fall Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We use Particle‐In‐Cell (PIC) simulations to investigate the charging characteristics inside deep cavities on the lunar surface under the solar wind plasma conditions. Specifically, we systematically study the dependence of the cavity bottom potential on plasma flow velocity and cavity aspect ratio.

Quantifying Serpentinization‐Driven Remagnetization From Ridge Axis to Subduction Zone Using Quantum Diamond Microscopy

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Diachronous ferromagnetic (sensu lato) mineral populations are often juxtaposed on micrometer‐to‐millimeter scales. This poses significant challenges for extracting reliable paleomagnetic information because standard methods measure bulk magnetic moments and cannot distinguish between magnetic minerals with overlapping demagnetization spectra.
