China puts out ‘most detailed’ map of the moon’s surface
- Dozens of researchers spent a decade compiling data from lunar missions to create a high-resolution picture of the surface
- The work also gives new insight into the moon’s past

The map reveals the composition and structure of the lunar surface as well as reflecting the latest understanding of the moon’s evolutionary history.
In a paper published in the peer-reviewed journal Science Bulletin on May 30, the researchers said such maps played an essential role in scientific research, exploration planning, and landing site selection for missions to the Earth’s only natural satellite.

The researchers said the United States Geological Survey had previously made a number of regional maps of the moon based on data brought back by the Apollo missions. However, those maps were completed at different times with different standards, and were therefore not really compatible.
The lunar mapping project started in 2012 by geologists Ouyang Ziyuan and Liu Jianzhong from the Institute of Geochemistry, Chinese Academy of Sciences in Guiyang.
To create the 1:2.5 million-scale map, researchers first divided the moon into 30 quadrangles and mapped them individually using the same standards. Then they stitched the quadrangles together to create a complete map.
