Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

Bacillus subtilis Spore Resistance to Simulated Mars Surface Conditions

Frontiers 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.

Mars Lander/Rover vehicle development: An advanced space design project for USRA and NASA/OAST [PDF]

A design is proposed for a Mars Lander/Rover (MLR) for use in gathering needed environmental and surface information. The design focus will be upon a Mars Lander/Rover that will leave an orbit around Mars, reenter and soft land on the Martian surface ...

Jarosite stability on Mars [PDF]

, 2005
Jarosite, a potassium (sodium) iron sulphate hydrated mineral, has recently been identified on the martian surface by the Opportunity rover. Using recent thermochemical data [Drouet and Navrotsky, 2003, Geochim. Cosmochim.

In Situ Detection of Opal‐A in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract We report the in situ detection of amorphous hydrated silica in the Bills Bay abrasion patch, located in the eastern portion of the Margin Unit between the rim of Jezero crater and the western delta. Here, hydrated silica co‐occurs with olivine, Fe‐Mg carbonates, secondary Fe‐Mg silicates, and hydrated Mg‐sulfate as determined by UV Raman ...

Predicted Diurnal Variation of the Deuterium to Hydrogen Ratio in Water at the Surface of Mars Caused by Mass Exchange with the Regolith [PDF]

, 2019
Regolith on Mars exchanges water with the atmosphere on a diurnal basis and this process causes significant variation in the abundance of water vapor at the surface. While previous studies of regolith-atmosphere exchange focus on the abundance, recent in-

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

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 ...
