Today, with the rapid development of global technology, Chinese scientists are leveraging the power of artificial intelligence to drive new advances in lunar scientific research. Recently, at the 2025 China International Big Data Industry Expo, the Institute of Geochemistry, Chinese Academy of Sciences, officially launched the "Lunar Science Multimodal Professional Large Model V2.0". This advanced model has endowed the "Digital Moon" cloud platform with a powerful "smart brain", significantly improving the efficiency of lunar geological research.
Research on the geological evolution of the moon usually requires analyzing geological structures such as impact craters. The number, size, depth, and shape of these craters are important references for understanding the moon's impact history and its effects. Currently, scientists have discovered more than one million impact craters on the moon with diameters exceeding 1 kilometer, and the number of craters smaller than 1 kilometer is difficult to accurately count. Relying on manual identification, it is almost impossible to complete the screening of these craters.
The application of the "Lunar Science Multimodal Professional Large Model" allows researchers to simply input images of impact craters and related questions, and the system can quickly provide information about the shape, size, and formation age of the crater, along with detailed textual descriptions. This efficient working method significantly improves research efficiency, allowing scientists to focus more on deeper studies.
During the launch, researcher Liu Jianzhong introduced that to achieve the training of this model, the team established a comprehensive multimodal data annotation specification, successfully building a labeled dataset containing more than 8,700 impact craters and 7,272 other lunar structures. After training, the model achieved an accuracy rate of 88% in classifying the age of impact craters and subcategories, and an accuracy rate as high as 93% in automatically identifying lunar structures.
In the future, according to the project plan, the "Digital Moon" cloud platform will be completed by 2027 and will be open and shared globally. This platform will not only provide powerful data support for scientists, but also create new opportunities for global lunar exploration and scientific research.
