China has released a significantly updated geological map of the Moon, giving scientists a more detailed picture of the lunar surface and its history.

The new map, completed by researchers at the Institute of Geology of the Chinese Academy of Geological Sciences, incorporates new scientific information from China’s Chang’e lunar exploration program, including samples returned from the Moon’s near and far sides.

The project is more than a new picture of the Moon. Scientists say the updated map provides an important reference for future lunar research, landing-site selection and exploration missions.

A Detailed New Map of the Entire Moon

The new lunar geological map has a scale of 1:5,000,000 and covers the entire Moon.

It identifies more than 13,000 impact craters and 81 impact basins while classifying 14 types of geological structures and 17 types of rocks across the lunar surface. The main map measures approximately 280 centimeters by 120 centimeters and includes additional maps covering the Moon’s polar regions.

That level of detail gives researchers a standardized way to study the Moon’s geological features and compare different regions.

Chang’e Missions Provided Critical New Data

One of the biggest reasons the map could be updated is the growing amount of scientific information coming from China’s Chang’e missions.

The Chang’e 5 mission, which launched in 2020, returned lunar samples to Earth. Analysis of those samples has provided evidence that volcanic activity on the Moon continued much later than previously believed, with some lunar basalt dating to roughly 2 billion years ago.

Then came Chang’e 6.

Launched in 2024, Chang’e 6 became the first mission to return samples from the far side of the Moon. Those samples provide scientists with direct geological information from a region that has historically been much less well understood than the near side.

The new geological map incorporates findings from that mission for the first time.

The Moon’s Far Side Gets a Closer Look

The far side of the Moon is particularly important to scientists because it differs significantly from the familiar near side.

For decades, researchers have had to rely heavily on orbital observations to study the far side. Chang’e 6 changed that by bringing actual samples from the region back to Earth.

Research published in Nature Sensors in 2026 used information from the Chang’e 6 sampling site to improve global maps of lunar chemistry. The study found that combining far-side sample data with orbital observations can provide better constraints on the composition and geological characteristics of the Moon’s surface.

Those findings can help researchers understand how different regions of the Moon formed and evolved.

Scientists Are Revising the Moon’s Geological Timeline

The updated map also reflects changes in how scientists understand the Moon’s geological history.

Researchers have revised the boundaries of several ancient periods in the lunar geological timeline, including the Aitkenian, Nectarian and Imbrian periods.

These changes may sound highly technical, but they are important because geological maps are essentially timelines written across a planetary surface.

Different rocks, craters and impact basins provide clues about when major events occurred. As scientists obtain better samples and more precise measurements, they can refine the ages assigned to different geological formations.

Why Lunar Geological Maps Matter

A geological map isn’t simply useful for academic research.

As nations prepare for another era of lunar exploration, scientists and engineers need detailed information about where spacecraft can safely land and what kinds of terrain they may encounter.

A comprehensive lunar map can help researchers evaluate:

• Potential landing locations
• Geological hazards
• Ancient volcanic regions
• Impact craters and basins
• Lunar rock and mineral distributions
• Polar terrain
• Potential scientific targets
• Routes for future robotic missions

China’s new map is therefore expected to provide baseline information for future lunar exploration and research.

The Lunar South Pole Could Be Especially Important

The Moon’s polar regions have become a major focus of international lunar exploration.

Scientists are particularly interested in permanently shadowed areas because they may contain deposits of water ice. Water could eventually become an important resource for future lunar missions and potentially longer-term human activity.

China’s new project includes separate geological maps of the north and south polar regions, giving researchers additional information for studying these areas.

As lunar missions become more ambitious, detailed maps could play an increasingly important role in deciding where spacecraft should go.

China Is Building a Larger Lunar Exploration Strategy

The updated geological map also fits into China’s broader ambitions in space.

China has increasingly demonstrated its ability to conduct complex lunar missions, including landing spacecraft on the far side and returning samples to Earth.

The country’s latest geological mapping effort could also influence how future planetary maps are created. According to Space.com, Chinese researchers describe the mapping approach as part of an effort to establish standards that could eventually be extended to mapping other planetary bodies.

That means the significance of the project could extend beyond the Moon.

How It Compares With Earlier Lunar Maps

China previously released a high-resolution global geological atlas of the Moon in 2024. That project included a 1:2.5 million-scale geological map, along with maps showing lunar rock types and major geological structures.

The latest update incorporates additional scientific discoveries made since then, particularly information obtained from the Chang’e 5 and Chang’e 6 missions.

In other words, the new map represents an evolving scientific picture rather than a completely new understanding created from scratch.

The Moon Is Still Revealing Its Secrets

Despite being Earth’s closest natural neighbor, the Moon still contains major unanswered questions.

Scientists continue to investigate when volcanic activity stopped, how the lunar crust developed, why the near and far sides are so different and how enormous impact events shaped the surface.

New samples are helping answer some of those questions.

A 2026 Nature Communications study noted that samples from Chang’e 5 and Chang’e 6 have enabled major advances in understanding lunar geological evolution, particularly the history of basaltic volcanism.

The updated geological map brings many of those discoveries together in a single scientific framework.

What Comes Next?

The new China geological map of the Moon arrives at a time when lunar exploration is accelerating.

China is pursuing additional Chang’e missions and has ambitions for a long-term lunar research presence. The United States and other nations are also planning new lunar missions, making detailed geological information increasingly valuable.

As more spacecraft visit the Moon and more samples are collected, today’s map will inevitably be updated again.

That’s one of the most interesting aspects of lunar science: every mission has the potential to change what researchers think they know about Earth’s nearest celestial neighbor.

The Bottom Line

China’s updated geological map of the Moon represents an important step in modern lunar science.

With more than 13,000 craters, 81 impact basins, 14 geological structure categories and 17 rock types, the map provides researchers with an extensive reference for studying the Moon.

More importantly, it incorporates data from the Chang’e 5 and Chang’e 6 sample-return missions, including the first geological samples ever collected from the Moon’s far side.

As humanity prepares for a new era of lunar exploration, having an accurate geological map could prove just as important as having the rockets and spacecraft needed to get there.
