Mansbach et al. [2024] provide the first magnetically focused analysis of samples collected by the Perseverance Rover. They find that those samples contain iron oxides with titanium and chromium components and could thus be recorders of magnetization acquired in the presence of Mars’ ancient dynamo field. Studying magnetization in a lab allows us to date and get detailed understanding of the magnetization history of a given sample. As such, this kind of analysis is key to providing answers to fundamental questions concerning the Martian dynamo evolution, which is linked to the thermal history, climate, surface processes, and frankly, the entire planetary system.
