An in-situ ground-penetrating radar survey of Martian subsurface structure has revealed that a basin on the red planet has a dry and multi-layered shallow subsurface. The results published on 26 September in the journal Nature are based on a ground-penetrating radar survey of the subsurface structure in a southern marginal area of the Utopia Basin conducted by China's Mars rover Zhurong of the Tianwen 1 mission.
