英文摘要As the largest basin on Mars, Utopia Planitia has both experienced and recorded variations of the Martian palaeoclimate. Layered subsurface structures have been identified by ground-penetrating radar in southern Utopia Planitia but lateral variations of the subsurface, potentially linked to the Martian palaeoclimatic evolution, have not been investigated. Here we report the lateral frequency-variation patterns of Zhurong radar reflections and interpret them as buried polygonal terrain below a depth of 35 m. Sixteen polygonal wedges were identified within similar to 1.2 km distance, suggesting a wide distribution of such terrain under Utopia Planitia. The contrast above and below similar to 35 m depth represents a notable transformation of aqueous activity or thermal conditions in the Late Hesperian-Early Amazonian. The interpreted buried polygons, possibly generated by freeze-thaw cycles, imply that there was a strong palaeoclimatic variability at low-to-mid latitudes (similar to 25 degrees N), potentially due to the high obliquity of ancient Mars. The Zhurong rover identified polygonal terrain at a depth of 35 m under Utopia Planitia on Mars. This finding suggests that the mid-latitudinal region experienced a cold and wet environment near the freezing point of water around the Hesperian-Amazonian transition, possibly induced by Mars's high obliquity.
