"Mars' Zhurong Rover Uncovers Enigmatic Subsurface Polygons"
China's Zhurong rover, equipped with a ground-penetrating radar system, has detected irregular polygonal wedges buried beneath the surface of Mars in Utopia Planitia. These features, measuring from centimeters to tens of meters across, are believed to have formed billions of years ago due to freeze-thaw cycles or volcanic activity. The radar scans provide important local details of shallow structures and composition, complementing orbital radar explorations. The discovery suggests a wide distribution of similar terrain and indicates a significant paleoclimatic transformation on Mars.
