Surface Geology and Evolution of Asteroid Ryugu: Insights From Hayabusa2 Global Mapping

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Rubble‐pile asteroids, characterized by loose aggregates of debris held together by gravity, represent both a significant planetary hazard and a key to understanding planetesimal formation. Geologic mapping of these bodies provides essential insights into their origins, evolution, and surface processes.

Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

Magnetic Signature of the Corona Lava Tube (Lanzarote, Canary Islands), a Lunar and Martian Planetary Analog

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lava tubes and caves are key exploration targets on the Moon and Mars due to their potential to serve as natural infrastructure for future crewed missions. However, identifying these structures efficiently and reliably remains a major challenge.

Formation of Compact Aggregate Piles on a Surface Through Dissipation of Kinetic Energy Associated With Horizontal Motion

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Accumulation of dust on the Lunar and Martian surfaces plays a critical role in both surface evolution and human exploration efforts, limiting equipment lifetimes and obscuring optical surfaces. Yet, the underlying physics of surface soiling is still poorly understood.

Forecasting Local Geomagnetic Disturbances Using Machine Learning: A Multi‐Station Approach

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetic indices such as SYM‐H capture global disturbances but fail to resolve regional impacts critical for infrastructure resilience. We present a machine learning model to forecast the Local Disturbance Index (LDi), a validated regional geomagnetic index.

The UK Met Office’s Coronal Mass Ejection (CME) Ensemble Prediction System

Space Weather, Volume 24, Issue 7, July 2026.
Abstract We describe the 24‐member Coronal Mass Ejection (CME) ensemble prediction system that is used operationally at the UK's Met Office Space Weather Operations Center (MOSWOC) to forecast the arrival time of CMEs at Earth. The ensemble system was built on ad‐hoc assumptions and there is the need to investigate whether the technique can be improved
