Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Obscuration of Crystalline Ca‐Sulfate in XRD and Raman Data When Coated by Amorphous Ferric Sulfate: Implications for the Amorphous Components at Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Throughout Gale crater on Mars, the Curiosity rover has found high abundances (15–73 wt%) of X‐ray amorphous materials in the rocks and sediments. The composition of this amorphous fraction is primarily calculated by subtracting crystalline abundances measured by the Chemistry & Mineralogy X‐Ray Diffractometer (CheMin) from bulk elemental ...

A Study on CO2 ${\text{CO}}_{2}$ Supersaturation in the Martian Southern Polar Night Using Mars Global Surveyor Radio Occultation Profiles Rederived With Mars Climate Sounder Temperature Climatology

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We investigate CO2 ${\text{CO}}_{2}$ supersaturation in the Martian southern polar night using rederived vertical profiles from Mars Global Surveyor (MGS) radio occultation (RO) measurements. Supersaturation, which affects not only local condensation but also the polar and global atmospheric dynamics, occurs when temperatures fall below the ...

Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.
