Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Bidirectional Energy Transfer via Simultaneous Wave‐Particle Resonances in Inhomogeneous Space Plasmas

open access: yesAGU Advances, Volume 7, Issue 4, August 2026.
Abstract Wave‐particle resonance is a key mechanism for energy transfer in collisionless plasmas with important implications for wave excitation and particle acceleration. Cyclotron resonance occurs when a particle's gyromotion synchronizes with the wave fields, with their interactions usually describable by quasilinear diffusion or nonlinear trapping.

Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

Migrating and Nonmigrating Neutral Mass Density Tides From GRACE‐FO Observations for Solar Minimum Conditions

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study presents the migrating and nonmigrating thermospheric neutral mass density tides from the Gravity Recovery And Climate Experiment Follow‐On (GRACE‐FO) observations under solar minimum conditions (year 2020). The observed densities are first mapped to a reference altitude of 500 km using an empirical model (NRLMSIS 2.0) to remove the

A Contrasting TEC Behavior Over the Low‐Latitude Post‐Midnight Sector During Recovery Phases of May and October 2024 Storms: Possible Role of PPEF, DDEF, and O/N2

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The present study reports on the variability of the post‐midnight ionosphere over the low‐latitude sector during the recovery phases of the May and October 2024 storms. Multi‐instrument observations, comprising global navigation satellite system total electron content (TEC), F‐layer peak height, electron density profiles, and column O/N2 ...
