The chemical effects of the Martian environment on power system component materials: A theoretical approach [PDF]
In the foreseeable future, an expedition may be undertaken to explore the planet Mars. Some of the power source options being considered for such a mission are photovoltaics, regenerative fuel cells and nuclear reactors.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Martian north polar cap summer water cycle
, 2016 A key outstanding question in Martian science is 'are the polar caps gaining or losing mass and what are the implications for past, current and future climate?' To address this question, we use observations from the Compact Reconnaissance Imaging ...

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

Soil development and sampling strategies for the returned Martian surface samples [PDF]
Sampling of the Martian surface materials should be based on the experience gained from the study of soils and rocks collected in cold, dry environments, i.e., dry valleys of Antarctica.

Data assimilation insights on selecting the most valuable atmospheric measurements [PDF]
, 2012 We discuss how objective guidance on selecting the most valuable atmospheric measurements on future Mars spacecraft missions can be provided through already developed Martian atmospheric data assimilation systems, and in particular through Observing ...

A hybrid origin for the Martian atmosphere
Geochemical Perspectives LettersThe Martian isotopic record displays a dichotomy in volatile compositions. Interior volatiles from the mantle record a chondritic heritage (e.g., H, N, Kr, Xe) whereas the atmospheric reservoir of Kr and Xe - which do not currently experience escape - record heritage from a solar-like source.

Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.
