Atmospheric Ion‐Neutral Coupling as a Potential Driver for Saturn's Magnetospheric Antisunward Electric Field

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC

Advanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.
A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.

A Multifrequency Global View of Callisto’s Thermal Properties from ALMA

The Planetary Science Journal
We present thermal observations of Callisto’s leading and trailing hemispheres obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz), 1.3 mm (233 GHz), and 3 mm (97 GHz).

Ion‐Selective Electrode Robustness to Environmental Conditions Relevant to Spaceflight Missions to the Outer Solar System

Electroanalysis, Volume 38, Issue 2, February 2026.
Future in situ missions to ocean worlds of the outer solar system would benefit from the aqueous chemical measurements provided by ion‐selective electrodes (ISEs). Here, we verify the performance of ISEs after exposure to environments expected during outer Solar System missions, specifically near‐decade scale transit times, anhydrous conditions, low ...

Revealing Callisto’s Near-subsurface Thermophysical Properties with ALMA Calibration Data

The Planetary Science Journal
Thermal images at different wavelengths probe varying subsurface depths of planetary bodies and therefore can inform us about their compositions, thermophysical properties, and impact histories.

Pitch Angle Distributions of Energetic Electrons Near Ganymede: Galileo EPD Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Galileo flew‐by Ganymede six times between 1996 and 2000. The Energetic Particles Detector (EPD) performed energy resolved, directional electron measurements, and together with the magnetometer data, pitch angle distributions (PADs) could be derived.

Inductive Response of Enceladus' Ice Shell and Potentially Stratified Ocean

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Saturn's moon Enceladus harbors a global subsurface ocean beneath its icy crust. Understanding the structure and composition of this ocean and ice is critical to assessing its potential habitability. Modern electromagnetic (EM) sounding techniques, which measure a celestial body's induced response to external electromagnetic fields, offer a ...

A High-precision Dynamical Model of Callisto: Incorporating Rotation Effects within Multilayer Internal Structure Models

The Astrophysical Journal
China is planning to launch the “Tianwen-4” mission around the year 2030, with its aim being the exploration of Jupiter and its moon, Callisto. Within the realm of deep space exploration, the accuracy of ephemerides is of great importance.

On the Origin and Dynamical Evolution of Jupiter’s Moon Amalthea

The Astrophysical Journal
Interior to the orbits of Jupiter’s iconic Galilean moons are four small satellites with individual mean radii R  ≲ 84 km. Multiple lines of evidence suggest that these bodies formed at a more distant location in Jupiter’s circumplanetary disk before ...
