China to produce world’s first AI-based Mars geological map by 2028

China is advancing a new generation of full-Mars geological mapping, led by Tianwen-3 chief scientist Hou Zengqian, using AI-driven intelligent mapping and data from the Tianwen-1 mission. The project integrates multimodal data including imagery, spectral, radar, and gravity information. The first version of a 1:5,000,000 global Mars geological map is planned for completion by the end of 2028, marking the world’s first intelligent Mars geological map.

This signals a shift in planetary science toward AI-assisted cartography, where automated integration of diverse datasets could accelerate geological interpretation beyond manual methods. For the space exploration sector, it underscores China's intent to lead in AI-driven off-world mapping, potentially setting a technical benchmark for future missions. The open question is whether the 2028 timeline holds and how this map's accuracy compares to traditional, human-curated geological charts, which will determine its scientific credibility.
