DepthFormer: Depth‐Enhanced Transformer Network for Semantic Segmentation of the Martian Surface From Rover Images

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract The Martian surface, with its diverse landforms that reflect the planet's evolution, has attracted increasing scientific interest. While extensive data is needed for interpretation, identifying landform types is crucial. This semantic information reveals underlying features and patterns, offering valuable scientific insights.

The Link Between Subsurface Rheology and Ejecta Mobility: The Case of Small New Impacts on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The dynamics of crater ejecta are sensitive to the material properties of the target, much like the crater size and morphology. We isolate and quantify the effect of target properties on the ejecta mobility (EM) ‐ the maximum radial extent of ejecta scaled by the crater radius.

Episodic flood inundations of the northern plains of Mars [PDF]

, 2003
Throughout the recorded history of Mars, liquid water has distinctly shaped its landscape, including the prominent circum-Chryse and the northwestern slope valleys outflow channel systems, and the extremely flat northern plains topography at the distal ...

Gravity and Magnetic Field Signatures in Hydrothermally Affected Regions on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Multiple lines of evidence indicate that liquid water‐rock interactions occurred on ancient Mars, particularly within the crust, where hydrothermal systems have been hypothesized. Such hydrothermal circulation (HC) can significantly lower temperatures in the crust, thereby restricting the viscoelastic relaxation of impact craters. Craters with

Anomalies of Density, Stresses, and the Gravitational Field in the Interior of Mars

, 2012
We determined the possible compensation depths for relief harmonics of different degrees and orders. The relief is shown to be completely compensated within the depth range of 0 to 1400 km.

Statistical Characteristics of Nighttime ULF Waves Observed on the Surface of Mars by InSight

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) Fluxgate Magnetometer returned data from the Martian surface throughout the course of the InSight mission, between November 2018 and May 2022. Ultra‐low frequency (ULF) electromagnetic waves are commonly observed by InSight during nighttime hours.

Global Transport of Chlorine Species in the Martian Atmosphere and the Resulting Surface Distribution of Perchlorates

Journal of Geophysical Research: Planets, Volume 130, Issue 3, March 2025.
Abstract Recent observations by instruments aboard the ExoMars Trace Gas Orbiter (TGO) have revealed the seasonal presence of hydrogen chloride (HCl $\text{HCl}$) in the Martian atmosphere. This discovery may have important implications for Martian photochemistry as chlorine species are chemically active, and it may provide a link between the ...

Atmospheric Gravity Waves in Mars' Lower Atmosphere: Nadir Observations From OMEGA/Mars Express Data

Journal of Geophysical Research: Planets, Volume 130, Issue 3, March 2025.
Abstract We present the detection and characterization of mesoscale waves on the lower clouds of Mars (20–40 km) using hyperspectral images from the Observatoire pour la Minéralogie, l’Eau, les Glaces et l’Activité (OMEGA) onboard the European Mars Express space mission.
