Tracing a Wet Past and Diverse Provenances in Gale Crater, Mars, With Lithium Content Using ChemCam on the Curiosity Rover

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The incompatible behavior of Lithium during magmatic differentiation and high mobility during aqueous alteration make it a valuable tracer of crustal processes on Mars. Its preferential incorporation into secondary phyllosilicates further links Li to clay‐forming environments, which are critical for evaluating past aqueous activity and ...

Modeling the Crustal Magnetic Field of Mars With Physics‐Informed Neural Networks

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Satellites orbiting Mars have measured crustal magnetic fields up to two orders of magnitude stronger than those on Earth. Although Mars currently lacks an active global magnetic field, this magnetization preserves a valuable record of the planet's early dynamo activity and crustal evolution.

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

open access: yesJournal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.
