A reporter from Science and Technology Daily learned on January 6, 2026, from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) that by analyzing high-frequency radar data obtained by the Zhurong rover, researchers have discovered evidence of significant water activity on the Martian surface until approximately 750 million years ago. This finding extends the known history of water on Mars by several hundred million years, providing new evidence for reassessing the planet's climatic evolution, geological processes, and its potential habitability for life. The related research findings have been published in the journal National Science Review.
