A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

The Apparent Involvement of ANMEs in Mineral Dependent Methane Oxidation, as an Analog for Possible Martian Methanotrophy

Life, 2011
On Earth, marine anaerobic methane oxidation (AOM) can be driven by the microbial reduction of sulfate, iron, and manganese. Here, we have further characterized marine sediment incubations to determine if the mineral dependent methane oxidation involves ...

Photovoltaic array for Martian surface power [PDF]

Missions to Mars will require electric power. A leading candidate for providing power is solar power produced by photovoltaic arrays. To design such a power system, detailed information on solar-radiation availability on the Martian surface is necessary.

Analysis of High Frequency Marsquake Swarms Informed by Deep Learning

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract NASA's InSight mission has provided an unprecedented snapshot of Mars' seismicity, despite data analysis challenges arising from low signal‐to‐noise ratios (SNR) and single‐station constraints. High frequency (HF) events—the most common type—were initially assumed to propagate through shallow crustal layers.

Mars Crater Production Function Based on Mapped Crater Populations

Space: Science & Technology
The Martian isochrons are the basis in analyzing the impact flux and surface dating, and currently, they are usually derived from those of the Moon because no samples have been collected from Mars.

Geophysical Impacts and Spectroscopic Identification of a Hydrous Iron Sulfate on Icy Worlds

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Over geologic time‐scales, large volumes of exogenic sulfur ions from Io's plasma torus have been supplied to the surface of Europa and Ganymede, which, combined with recent interpretations of orbiter images, dynamical modeling, and surface‐subsurface exchange, suggests further sulfur transport into the interior of the icy worlds.

Short‐Term Effect of Mars‐Like Radiation on Carbon and Oxygen Isotope Compositions of Carbonates

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The stable isotope composition of carbonates records the environmental formation conditions and can indicate potential biosignatures if formed biologically. Martian meteorite carbonates display unusually high δ13C values, not explained using known terrestrial processes.

Reconfigurable Intelligent Surface Deployments for Mars: Communication and Localization Across Diverse Terrains

IEEE Open Journal of the Communications Society
Space exploration has witnessed a steady increase since the 1960s, with Mars playing a significant role in our quest for further knowledge. As the ambition to colonize Mars becomes a reality through the collaboration of private companies and space ...

Samples from Martian craters: Origin of the Martian soil by hydrothermal alteration of impact melt deposits and atmospheric interactions with ejecta during crater formation [PDF]

The origin of the Martian soil is an important question for understanding weathering processes on the Martian surface, and also for understanding the global geochemistry of Mars.

Dust and Cloud Transport by Traveling Waves in the Martian Atmosphere Studied With Mars Climate Sounder

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Traveling waves in the Martian atmospheres play a crucial role in determining the weather and climate, particularly at mid‐to‐high latitudes. Previous observations have shown that these waves become prominent from early autumn to late winter in the northern hemisphere, influencing the dust cycle.
