  • 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.

  • High perchlorate/chloride ratios at the Phoenix landing site in the Martian northern polar region could have formed by specific relative humidity and temperature conditions coupled with dust transport, according to experiments and thermodynamic modeling.

  • Laboratory experiments show that the type of iron mineral is the dominant factor controlling the chlorate/perchlorate (ClO3−/ClO4−) generation ratio on Mars over oxidation methods or atmospheric composition. Chlorate yields are found to exceed perchlorate yields by orders of magnitude in the current desiccated Martian conditions.
