Global Occurrence of Solitary Waves in the Martian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Time and Length Scales of the Martian Atmospheric Turbulence as Observed by the InSight Lander

Geophysical Research Letters
We provide a statistical analysis of the Martian near‐surface atmospheric turbulence based on in situ wind observations from NASA's InSight lander. We focus on the variations in length and time scales of the Martian atmospheric turbulence caused by the ...

Physics‐Informed Neural Networks for Modeling the Martian Induced Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Understanding the magnetic field environment around Mars and its response to upstream solar wind conditions provide key insights into the processes driving atmospheric ion escape. To date, global models of Martian induced magnetosphere have been exclusively physics‐based, relying on computationally intensive simulations. For the first time, we

ARAMIS: a Martian radiative environment model built from GEANT4 simulations

Journal of Space Weather and Space Climate
A new model of the Martian surface radiative environment has been built: Atmospheric RAdiation Model for Ionizing spectra on martian Surface (ARAMIS). Based on Monte Carlo calculations, it offers high computational flexibility for surface flux spectra ...

Investigating the Impact of the Spatially Heterogeneous Surface Dust Cover on Martian Global Dust Event Occurrence

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The observed inter‐annual variability of Global Dust Events (GDE) occurrence on Mars remains challenging to understand and therefore to predict. Several hypotheses have been investigated so far, but a central aspect seems to be missing: How the heterogeneity of the surface dust cover and regolith particle size distributions relate to regional ...

The search for ancient life on Mars using morphological and mass spectrometric analysis: an analog study in detecting microfossils in Messinian gypsum

Frontiers in Astronomy and Space Sciences
Hydrated sulfate deposits have been detected on Mars. A spaceflight instrument capable of detecting microfossils in these salt deposits is highly important for the search for ancient life on Mars.

Martian sub-surface ionising radiation: biosignatures and geology [PDF]

Biogeosciences, 2007
The surface of Mars, unshielded by thick atmosphere or global magnetic field, is exposed to high levels of cosmic radiation. This ionising radiation field is deleterious to the survival of dormant cells or spores and the persistence of molecular ...
