Spatial Distribution and Plasmaspheric Ducting of Auroral Kilometric Radiation Revealed by Wind, Polar, and Arase

AGU Advances, Volume 6, Issue 4, August 2025.
Abstract Auroral Kilometric Radiation (AKR), the dominant radio emission from Earth, has been extensively studied, though previous analyses were constrained by limited spacecraft coverage. This study utilizes long‐term observations from Polar, Wind, and Arase spacecraft to generate comprehensive global AKR occurrence rate maps, revealing a high ...

Analysis, Testing, and Design of a UHF and HF Peer‐to‐Peer Communication System for the Europan Cryosphere

Earth and Space Science, Volume 12, Issue 8, August 2025.
Abstract This study presents a validated design of a dual‐band wireless relay system of “pucks” for through‐ice communication between a cryobot and a surface lander during a future exploration of the Europan cryosphere. The design of a terrestrial demonstration system and the results of a 103 m through‐ice system test in a relevant environment near ...

M‐Shell and Local Time Variability of the Electron and Magnetic Environments at the Orbit of Callisto as Observed by the Juno and Galileo Missions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract Jupiter's moon Callisto orbits in a highly variable magnetospheric environment depending on its position relative to the Jovian current sheet. The Juno and Galileo missions have visited the Jovian magnetosphere and crossed Callisto's orbit several times in a variety of configurations, providing an opportunity to better characterize Callisto's ...

Diagnosing the Rapid Loss of Outer Radiation Belt Electrons Due To Strong Chorus‐Driven Wave‐Particle Interactions Along an Electron Injection Path

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract Multi‐spacecraft data demonstrate that intense chorus waves are excited during electron injection events that drive rapid radiation belt electron loss across a limited energy range from ∼ ${\sim} $100 to 300 keV on sub‐drift timescales through strong pitch angle diffusion.
