Dark‐Toned Halite‐Enriched Veins Above the Marker Band Record a Drying Environment in Gale Crater

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Martian surface preserves evidence of a global climate transition from wetter to drier conditions, but the nature of the fluids involved in this evolution remains poorly constrained. In Gale crater, the clay‐sulfate transition and presence of evaporite mineral assemblages can provide insights into the properties of these fluids and the ...

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Rock Coatings as Evidence for Late Surface Alteration on the Floor of Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract During the NASA Perseverance rover's exploration of the Jezero crater floor, coatings were commonly observed on rocks. These features may record past water‐rock‐atmosphere interactions on the crater floor, and understanding their origin is important for constraining the timing of potential water activity and habitability at Jezero.

Surface Dust Coverages on Rock Targets in Gale Crater: Influence of Elevation, Proximity to Aeolian Sand Fields and Seasonality

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Martian dust is mobilized throughout the year by local, regional, and global dust storms, influencing atmospheric opacity and inhibiting observations of the surface. Using Mars Hand Lens Imager (MAHLI) images and methods of Schmidt et al. (2018), https://doi.org/10.1029/2018je005553, areal dust coverages on 368 near‐horizontal, undisturbed ...

Nighttime and Early Morning Atmospheric Waves and Transient Turbulence at Jezero Crater, Mars, Observed by the Perseverance Rover

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We study atmospheric oscillations in Jezero crater, Mars, that occur at night and dawn over stable conditions of the planetary boundary layer. These atmospheric oscillations are sporadic and can have large amplitudes, resulting in important variations in the dynamic conditions of the atmosphere.
