Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

Comparison of Remotely‐Sensed Orbital and Rover‐Based In Situ Surface Orientation Analyses in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Satellite data have been used to estimate the three‐dimensional orientation of features on Mars inferred to be bedding planes to support interpretations of deposit characteristics and depositional environments. Opportunities to ground‐truth these estimates and to understand the geologic information recorded by surfaces measured from orbit are ...

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

Performance of hydrogen-rich materials in combination with lunar regolith for shielding against GCR, albedo, and SPEs on the surface of the moon studied using MULASSIS [PDF]

AIP Advances
The moon is the most likely location for future human habitation. The radiation exposure from the combination of galactic cosmic rays, solar particle events, and albedo radiation on the Moon’s surface is one of the major obstacles to permanent settlement

Widespread Landslide Activity in an Extreme Wet Season and Implications for Regional Sediment Management, Eastern San Francisco Bay Area, California

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Watershed sediment production is expected to increase in a warmer future with more extreme rain, with cascading effects throughout drainage and sediment‐transport networks. This study investigated landscape‐scale sediment movement in the eastern San Francisco Bay area, California, USA, during the extreme 2016–2017 wet season that brought major

Ground-penetrating radar investigation of regolith thickness on a periglacial alpine summit flat, Uinta Mountains, Utah, USA

Arctic, Antarctic, and Alpine Research
Summit flats are low-relief, gently sloping landforms common in periglacial mountain environments. Apart from at their edges where summit flats are truncated by glacial headwalls and at their crests where isolated tors are occasionally present, bedrock ...

Reconstructing Europa's Atmosphere From H2+ ${\mathbf{H}}_{\mathbf{2}}^{+}$ Pickup Ions Detected During the Juno PJ45 Flyby

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract We use a suite of single‐species (H2 ${\mathrm{H}}_{2}$) and multispecies (H2+O2+H+O ${\mathrm{H}}_{2}+{\mathrm{O}}_{2}+\mathrm{H}+\mathrm{O}$) Direct Simulation Monte Carlo models of Europa's atmosphere to interpret the H2+ ${\mathrm{H}}_{2}^{+}$ pickup ions detected by Juno at distances beyond 2 $2$ Europa radii RE $\left({R}_{E}\right ...

Dynamics of regolith dunes on small planetary bodies [PDF]

EPJ Web of Conferences
The surfaces of small planetary bodies are covered with regolith which keeps evolving with time. Studying the dynamics of these regolith can explain various surface features observed in recent space explorations.

Rheology and Structure of Fe‐Mg‐Ca Enriched Silicate Melt: Benchmarking Viscosity Models for an Exotic Planetary Composition

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Silicate melt viscosity plays a pivotal role in the evolution of rocky bodies within the Solar System, exerting first‐order control on mantle differentiation and stratification, while dictating the metal‐silicate separation and the subsequent volcanic activity.
