Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

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.

Origin of the Bulge Topography Within Caloris Basin, Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.

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 ...
