Widespread Diagenesis at Unconformities in Gale Crater as Inferred From the Curiosity Rover and From Orbit

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract NASA's Curiosity rover has found widespread evidence of alteration in sedimentary rocks in Gale crater, Mars driven by interactions with fluids both before and after lithification (early and late diagenesis). Most notably, Curiosity observed distinctive color, chemical, and mineralogical changes interpreted as evidence of diagenesis at the ...

Questioning the Reliability of Methane Detections on Mars by the Curiosity Rover

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Over the past decade, the Tunable Laser Spectrometer (TLS) on NASA's Curiosity rover has reported several detections of methane on Mars, attracting attention due to the potential astrobiological implications of its presence. Here, we re‐analyze published TLS data, identifying issues in data robustness and reduction.

Gravity and Radio Science Investigation at the Moons of Uranus to Reveal Subsurface Oceans and Characterize Interior Structures

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The prospect that the five major moons of Uranus could host subsurface oceans makes them high‐priority targets for future exploration. Different techniques can be used to search for deep oceans in these objects. Here, we focus on ocean detection and characterization from measurements of the moons' response to the gravitational tides and ...
