Mars Thermospheric Variability: Disentangling the Influence of Irradiance, Dust, and Dynamics

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present a comprehensive analysis of Martian thermospheric variability using nearly a decade of solar occultation measurements from the MAVEN Extreme Ultraviolet Monitor (EUVM). These data provide vertical profiles of CO2 ${\text{CO}}_{2}$ density and temperature from ∼130 ${\sim} 130$ to 180 km at dawn and dusk, enabling the investigation ...

New Climatology of Martian Water Vapor Column Abundance Derived From NOMAD LNO Nadir Observations Over Martian Years 34–38

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present a new climatology of Martian water vapor column abundance derived from nadir dayside observations made by the Nadir and Occultation for MArs Discovery (NOMAD) instrument suite as part of the ExoMars Trace Gas Orbiter (TGO) mission. H2O vertical column densities are retrieved by applying an Optimal Estimation inversion scheme to the ...

Magnetic Reconnection as a Potential Trigger for Magnetotail Flapping at Mars: Insights From MAVEN and Tianwen‐1 Observations

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Magnetotail current sheet (CS) flapping is a universal plasma phenomenon observed at multiple planets, yet its triggering mechanisms remain poorly understood outside of Earth. At Mars, single‐spacecraft observations have also reported tail flapping, but the processes responsible for its onset have never been identified.

Magnetosphere of Mars at Almost Radial Interplanetary Magnetic Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We have studied the structure of the Martian magnetosphere under conditions of an almost radial interplanetary magnetic field (IMF). Under such conditions, the currents driven by the motional electric field −1cVsw×BIMF ${-}\frac{1}{c}{\mathbf{V}}_{sw}\times {\mathbf{B}}_{\mathit{IMF}}$ are expected to be strongly reduced, and the induced ...

MAVEN Observations of the Martian Magnetospheric Response to Simultaneous Quasi‐Radial Interplanetary Magnetic Field and Low Dynamic Pressure

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The state of Mars' induced magnetosphere is highly dependent on upstream solar wind conditions. Changes in dynamic pressure alter the locations of magnetospheric boundaries such as the bow shock and induced magnetosphere boundary, while the orientation of the interplanetary magnetic field (IMF) impacts the formation of the bow shock.

A Planetary‐Scale Hydraulic Jump Driving Venus' Cloud Front

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Atmospheric motions generate clouds and influence planetary climate systems. Venus, permanently shrouded by sulfuric acid clouds, provides a striking example. Unlike the photochemically produced upper clouds, the lower cloud layer is thought to form through condensation driven by poorly understood atmospheric dynamics.
