Quantifying Water Ice in Regolith Mixtures via Infrared (1.2–2.5 μm) Reflectance Model Parametrization

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Water ice deposits occur on inner solar system bodies in sunlit and shadowed terrains. We develop approaches to remotely determine the mixing mode with regolith (areal vs. intimate), ice grain size, and abundance that reveal processes of ice formation, emplacement, and evolution.

POD-Galerkin modelling of the Martian atmosphere [PDF]

, 1999
The aim of this thesis is to seek a low-dimensional description of baroclinic instability in general, and of the Martian atmosphere in particular, where both forcing and spatial resonance are relevant to the dynamics of the system being analysed.

Perchlorates on Mars enhance the bacteriocidal effects of UV light

Scientific Reports, 2017
Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Pitted Terrain on Vesta and Implications for the Presence of Volatiles. [PDF]

, 2012
We investigated the origin of unusual pitted terrain on asteroid Vesta, revealed in images from the Dawn spacecraft. Pitted terrain is characterized by irregular rimless depressions found in and around several impact craters, with a distinct morphology

Experimental Aeolian Abrasion of Basalt Sands as an Analog for Producing Martian Dust

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Dust covers a significant portion of Mars' surface, with dust storms periodically engulfing the planet. Despite this, the origins of Martian dust are poorly understood, especially for ancient dust deposits. To address this deficit, we conducted experiments to replicate the mechanical abrasion of saltating sand grains in a Martian desert dune ...

Modeling the Redistribution of Dust Across the Martian Surface for Mars Years 24 to 36

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Global Dust Events (GDEs) transport huge amounts of dust across the Martian atmosphere. GDEs occur only every few Mars Years (MYs), but the reasons behind this inter‐annual variability remain poorly understood. The question whether surface dust exhaustion and subsequent replenishment explain this variability remains open.

Simultaneous Two‐Point Study of the Martian Bow Shock Affected by an Interplanetary Coronal Mass Ejection: Tianwen‐1 and MAVEN Observations

Geophysical Research Letters
The Martian bow shock (BS) plays a significant role in the Martian plasma environment. Based on observations from Tianwen‐1 and MAVEN, we first report two cases of simultaneous two‐point crossings of the Martian BS affected by an interplanetary coronal ...
