Saponite Bearing Material Excavated During the Formation of a Recent 25‐m‐Diameter Impact Crater in Southeastern Arabia Terra on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Context Imager (CTX), and High Resolution Imaging Science Experiment observations were analyzed for a 25‐m‐wide impact crater and associated ejecta deposits located in the dust‐covered Arabia Terra region.

An Aeolian Depositional Sequence Shaped by Near‐Surface Water at the Base of the Layered Sulfate Unit, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The basal strata of the orbitally defined Layered Sulfate unit (LSu) in Gale crater, Mars, marks the end of a major mineralogical transition from clay‐to sulfate‐bearing stratigraphy. This has previously been attributed to a period of significant aridification of Gale's climate. Here, we present ground‐based observations by the Curiosity rover

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

Distinct element method for static and flow mobility characteristics of lunar regolith based on particle shape characteristics

Yantu gongcheng xuebao
Since it exhibits uniquely grain shape, physical and mechanical characteristics, the lunar regolith is extremely important for utilization of in-situ resources, selection of base station location and construction in lunar exploration.

A Two‐Step Artificial Intelligence Approach for Correcting Space Weathering Effects in the Lunar Reconnaissance Orbiter Diviner Christiansen Feature Image

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Space weathering substantially distorts the Christiansen feature (CF) observed by Lunar Reconnaissance Orbiter (LRO) Diviner thermal infrared radiometer, obscuring the intrinsic compositional and thermophysical signals of lunar surface silicate minerals.

Modeling the Lunar Thermal Emission Phase Function With the Diviner Lunar Radiometer

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The lunar thermal emission phase function (EPF) describes the anisotropic variation in observed infrared emission and brightness temperature with illumination and viewing geometry. The EPF is caused by small‐scale surface roughness below the resolution of current orbital data sets.

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Gully erosion in India: Geo‐environmental controls and region‐specific characteristics

Geographical Research, Volume 64, Issue 2, May 2026.
Spatial statistical analyses using a novel spatial database of India‧s gully erosion landforms revealed that India has six major gullying‐affected regions, three of which (EU, DU, and KCH) are dominated by gully systems (gully networks), with badlands (vast intensely gullied landscapes) being predominant in the other three regions (YB, GP, and RU ...

Coupled Space Weathering: Nanophase Iron Formation by Micrometeoroid Impact and Solar Wind Sputtering

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the interplay between micrometeoroid impacts and solar wind irradiation is crucial for interpreting lunar surface evolution. Using reactive molecular dynamics simulations and surface binding energy (SBE) analyses, this study investigates the coupled effects of these two dominant space weathering processes on lunar regolith ...
