Resultant Force on Grains of a Real Sand Dune: How to Measure It?
Geophysical Research LettersBarchan dunes usually appear under the action of one‐directional fluid flows, being found on Earth, Mars, and other celestial bodies; however, although ubiquitous in nature, understanding dune dynamics at the grain scale is challenging due to the vast ...

Geology of the Selk crater region on Titan from Cassini VIMS observations [PDF]
, 2010 International audienceObservations of Titan obtained by the Cassini Visual and Infrared Mapping Spectrometer (VIMS) have revealed Selk crater, a geologically young, bright-rimmed, impact crater located similar to 800 km north-northwest of the Huygens ...

The Density of Liquid FeO and the Oxygen Contents of the Cores of Earth and Mars
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Oxygen is a possible light element in the cores of Earth and Mars. Its effect on the density and elastic properties of liquid iron is, therefore, important for estimating its abundance in planetary cores, from which conditions of core‐mantle equilibration could be constrained.

The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.

La puissance spatiale, permanences et changements
L'Espace PolitiqueThe term “space power” is increasingly used in the media to describe States that carry out missions with strong symbolic power, even if they do not possess independent resources.

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data
AGU Advances, Volume 7, Issue 6, September 2026.Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Numerical modeling has been a key component in the study of the Mars space environment, providing a comprehensive global representation that is not always easy to obtain in spacecraft measurements. However, there are inconsistencies in data‐model and model‐model comparisons, regardless of whether the simulation conditions are identical or ...
