Impacts of the GDS 2018 Global Dust Storm on Martian Ionosphere‐Thermosphere Coupling via Atmospheric Tides

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract In this study, we investigate the ionospheric and thermospheric responses to the 2018 Mars global dust storm (GDS 2018) by examining atmosphere–ionosphere coupling through tidal structures. Using Mars Atmosphere and Volatile EvolutioN Neutral Gas and Ion Mass Spectrometer observations, we analyze tidal amplitudes, phases, and inter‐species ...

Saturn's Auroral Dusk Sector Magnetosphere‐Ionosphere Coupling During Cassini's Proximal Orbits

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The final twenty‐two low‐altitude passes of the Cassini spacecraft enabled the determination of Saturn's field‐aligned currents (FACs) from magnetometer measurements at lower altitudes than previously achieved. We investigate southern dusk‐side FAC behavior with four objectives: how in situ MAG measurements compare to the highly variable ...

Modeling Kinetic Reconnection Onset in Global Magnetospheric Simulations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract We investigate the onset of magnetic reconnection in Earth's magnetotail using a coupled magnetohydrodynamic with embedded particle‐in‐cell (MHD‐EPIC) model, which self‐consistently links global magnetospheric dynamics to electron‐scale kinetic processes. Unlike standalone kinetic simulations with idealized boundary conditions, reconnection in

Global Characterization of the Compressional Components of Magnetic Wave Activity in Mercury's Foreshock Region

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Mercury's weak intrinsic magnetic field forms a small magnetosphere and thus a bow shock that decelerates the supermagnetosonic solar wind and reflects particles upstream, forming a foreshock in the quasi‐parallel region. This region is populated by backstreaming ions and electrons and associated wave activity.

A Magnetospheric Source for Near‐Planet Whistler‐Mode Waves at Venus

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The presence or absence of lightning in the atmosphere of Venus has important implications for atmospheric chemistry, potential chemical signatures of life, identifying volcanic activity, and quantifying potential hazards to future exploration missions.
