China plans to complete a geological map of the entire planet Mars by the end of 2028. This was reported by Xinhua News Agency, a partner of TV BRICS.

Hou Zengqian, an academician at the Chinese Academy of Sciences and chief scientist of the Tianwen-3 mission, spoke about the plans. According to him, based on the new data, experts will develop a Chinese system for the geological periodisation of Mars.

Research by the Zhurong rover has shown that around 3.5 billion years ago, an ancient ocean of continental scale existed on Mars. Scientists have also discovered evidence of a possible short-lived flood that may have occurred around 1.6 billion years ago. This data will be used in the compilation of the new map.
