Sliding and Burrowing Blocks of CO2 Create Sinuous “Linear Dune Gullies” on Martian Dunes by Explosive Sublimation‐Induced Particle Transport

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Martian linear dune gullies are landforms consisting of parallel and often sinuous channels with distinct levees and pit‐shaped endings that occur in the mid‐latitudes on Mars. Recent observations link their formation to sublimating CO2 ${\text{CO}}_{2}$‐ice blocks that slide downslope in early spring. Here we combine laboratory experiments in

Bacillus subtilis Spore Resistance to Simulated Mars Surface Conditions

open access: yesFrontiers in Microbiology, 2019
In a Mars exploration scenario, knowing if and how highly resistant Bacillus subtilis spores would survive on the Martian surface is crucial to design planetary protection measures and avoid false positives in life-detection experiments.

Physiological and technological considerations for Mars mission extravehicular activity [PDF]

open access: yes
The nature of the suit is a function of the needs of human physiology, the ambient environment outside the suit, and the type of activity to be accomplished while in the suit.

On the Impact Origin of Phobos and Deimos I: Thermodynamic and Physical Aspects

open access: yes, 2017
Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood.

Accretion and Differentiation of Vesta and the Mesosiderite Parent Body Inferred From Ni Stable Isotope Compositions

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

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]

open access: yes
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.
