The Chinese Academy of Sciences (CAS) has unveiled the “Geologic Atlas of the Lunar Globe,” the world’s first high-definition geologic atlas of the entire Moon. This groundbreaking atlas, developed over ten years by more than 100 researchers, provides an unprecedented level of detail about the lunar surface. It serves as a major scientific achievement, offering new insights into the Moon’s geological features that were previously unseen.

Key Features of the Geologic Atlas
The “Geologic Atlas of the Lunar Globe” provides detailed geological maps at a scale of 1:2,500,000, making it the most comprehensive lunar map to date. The atlas identifies 12,341 craters, 81 basins, and 17 rock types, presenting a detailed view of the Moon’s surface, its geological structures, and tectonic features.
The atlas includes:
- Detailed Geological Maps: Covering the entire lunar surface, these maps provide a closer look at the Moon’s geological and lithological characteristics.
- New Technical Standards: The atlas sets new benchmarks for lunar geological mapping, establishing guidelines that will influence future studies and exploration missions.
- Sector Diagrams: The atlas also features 30 sector diagrams called “Map Quadrangles,” which together form a complete visualization of the Moon’s surface.
Data from Recent Lunar Missions
This comprehensive atlas integrates data from recent lunar exploration missions, including China’s Chang’e project, which has been instrumental in enhancing our understanding of the Moon. Data from Chang’e missions, along with international sources, have been used to create a detailed picture of the Moon’s geology, surpassing previous maps created during the Apollo era. The inclusion of data from modern missions allows for a much more accurate and updated representation of the lunar surface.
A New Era of Lunar Exploration
Editor Liu Jianzhong highlights that the new geologic atlas addresses the limitations of older lunar geological maps, which have largely remained the same since the Apollo missions over half a century ago. The updated atlas aims to meet the evolving needs of lunar exploration and scientific research, offering a valuable resource for future missions.
The detailed geological maps can aid scientists in understanding the Moon’s formation and evolution, which is crucial for planning future manned and unmanned lunar missions. The maps can also help identify potential landing sites for future lunar exploration and mining activities.
Collaboration Across Institutions
The creation of this atlas was a collaborative effort led by the Institute of Geochemistry of the Chinese Academy of Sciences, with contributions from multiple organizations, including the Chinese Academy of Geological Sciences, China University of Geosciences, and Shandong University. This collaboration highlights the importance of pooling resources and expertise to achieve significant scientific milestones.
Comparison with Previous Lunar Maps
Before the release of this atlas, the USGS Astrogeology Science Center had published a geologic map of the Moon in 2020 at a scale of 1:5,000,000. The new geologic atlas surpasses this by providing a more detailed and accurate representation at twice the resolution, offering clearer insights into the lunar landscape.

A Valuable Resource for the Global Scientific Community
The “Geologic Atlas of the Lunar Globe” is expected to be a valuable resource for scientists worldwide. It offers new data that can be used in various research fields, including planetary science, geology, and space exploration. The atlas also serves as an educational tool, providing a detailed look at the Moon’s geological features for researchers, educators, and students interested in lunar science.
Future Prospects
As lunar exploration continues to advance, the “Geologic Atlas of the Lunar Globe” will play a crucial role in guiding future missions. The detailed mapping of the Moon’s surface will help inform decisions regarding landing sites, exploration targets, and resource utilization. The atlas not only enhances our understanding of the Moon but also paves the way for the next generation of lunar explorers.
This new geologic atlas marks a significant step forward in lunar exploration, offering a clearer view of our nearest celestial neighbor and opening new opportunities for scientific discovery.
