Formation of Continuum Emission Structures Associated With the Aurora
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Recent observations enabled by improvements in geospace remote‐sensing instrumentation have revealed the spatial structure of continuum emissions that appear to be associated with the aurora, but little is known about the formation and drivers of these structures.

Characterizing Ion‐Scale Fluctuations Around Dipolarization Fronts in Earth's Magnetotail
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract In the Earth's magnetotail bursty bulk flows are often associated with dipolarizing magnetic flux bundles. The leading edges of such earthward‐moving flux bundles are called dipolarization fronts (DF). In the present study we investigate the characteristics of ion‐scale oscillations embedded inside DFs, using observations from NASA's ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract This study presents a comprehensive statistical comparison of solar wind measurements between the OMNI database which contains data collected at L1 that is shifted to the bow shock nose, and near‐Earth observations from MMS, Cluster, and THEMIS missions near the bow shock nose.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Electric field instruments function by electrically coupling to the surrounding plasma, resulting in a response function that varies depending on local conditions. This variable coupling can complicate quantitative interpretation of wave measurements, yet is rarely considered.

Auroral Acceleration Generates Electron Beams in Jupiter's Middle Magnetosphere
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Observations made by the Juno spacecraft above Jupiter's polar regions have revealed that electrons accelerated toward Jupiter, which contribute to auroral emissions, are frequently accompanied by electrons accelerated away from Jupiter. These electrons should be observable as narrow electron beams in the middle magnetosphere, in accordance ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

Early Solar Wind and Dynamo Magnetic Field Topology Predictions for (16) Psyche and Other Asteroids
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Asteroid (16) Psyche is a metal‐rich body that might record an ancient coherent magnetization if some relict crust or mantle is preserved. Herein, we use magnetohydrodynamic simulations to predict (16) Psyche's field topology for several distinct pathways: (i) an early solar wind‐induced magnetization imparted after a larger body was impacted,

Influence of Mars Topography on Neutral Surface Radiation: Modeling and MSL/RAD Observations
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Since landing in 2012, the Radiation Assessment Detector (RAD) onboard the Mars science laboratory (MSL) Curiosity rover has encountered different local landscapes, which have induced variations in the local surface environment. The aim of this study is to include realistic and site‐specific local topography for any position in a radiation ...

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...
