Uncovering Mars' Enigmatic Geometric Patterns: Clues to its Watery History

China's Zhurong rover, equipped with a ground-penetrating radar system, has discovered irregular polygonal wedges beneath Mars' surface, believed to be formed by freeze-thaw cycles or cooling lava. These formations, found in Utopia Planitia, suggest a strong paleoclimatic variability on Mars billions of years ago. The rover's mission, which lasted longer than intended, aimed to study Mars' topography and composition but has entered hibernation and hasn't been heard from since.
