China’s Moon Atlas Is the Most Detailed Ever Made
The Geologic Atlas of the Lunar Globe doubles the decision of Apollo-era maps and can assist the house ambitions of China and different nations
The brand new Moon atlas took greater than 100 researchers over a decade to compile.

The Chinese language Academy of Sciences (CAS) has launched the highest-resolution geological maps of the Moon but. The Geologic Atlas of the Lunar Globe, which took greater than 100 researchers over a decade to compile, reveals a complete of 12,341 craters, 81 basins and 17 rock sorts, together with different primary geological details about the lunar floor. The maps have been made on the unprecedented scale of 1:2,500,000.
“Every question in geology starts with looking at a geological map,” says Ross Mitchell, a geophysicist on the CAS Institute of Geology and Geophysics in Beijing. The brand new lunar atlas is “really a resource for the whole world”, he says.
The CAS additionally launched a e-book known as Map Quadrangles of the Geologic Atlas of the Moon, comprising 30 sector diagrams which collectively type a visualization of the entire Moon.

Jianzhong Liu, a geochemist on the CAS Institute of Geochemistry in Guiyang and co-leader of the undertaking, says that present Moon maps date from the Nineteen Sixties and Nineteen Seventies. “The US Geological Survey used data from the Apollo missions to create a number of geological maps of the Moon, including a global map at the scale of 1:5,000,000 and some regional, higher-accuracy ones near the landing sites,” he says. “Since then, our knowledge of the Moon has advanced greatly, and those maps could no longer meet the needs for future lunar research and exploration.”
China will use the maps to assist its lunar ambitions and Liu says that the maps shall be helpful to different nations as they undertake their very own Moon missions. Three spacecraft have launched aiming for the Moon thus far this yr, and in Could, China intends to ship a craft to gather rocks from the Moon’s far facet.
With the up to date atlas, scientists will have the ability to higher perceive the historical past of the Moon, consider potential lunar sources and conduct comparative geological research. It can additionally inform the situation decisions of future missions, together with the place to construct a lunar analysis base, Liu says.
Carolyn van der Bogert, a planetary geologist on the College of Münster in Germany, says she was impressed by the quantity of labor that Chinese language colleagues have put into compiling the brand new atlas.
“We are looking forward to being able to interact with the map in a very detailed way,” she says.
Different-worldly cartography
The atlas, which is accessible in each Chinese language and English, was assembled utilizing knowledge from China’s lunar exploration programme, particularly the Chang’e-1 mission, which surveyed the lunar floor from orbit between 2007 and 2009, in accordance with Liu. “Chang’e-1’s camera conducted observation of lunar topography and geological structures, while its interference imaging spectrometer played a key role in identifying different rock types,” he says.
Observations made on the Moon’s floor by the Chang’e-3 and Chang’e-4 lander missions in 2013 and 2019, respectively, helped to confirm the accuracy of the Chang’e-1 knowledge. The atlas workforce additionally used knowledge from missions such because the Gravity Restoration and Inside Laboratory (GRAIL) and the Lunar Reconnaissance Orbiter, each launched by NASA, and India’s Chandrayaan-1 probe. “Some observations were highly complementary to the Chang’e missions. For instance, GRAIL’s data helped us identify all the deep fractures on the lunar surface,” Liu says.
Chinese language researchers began to compile the maps in 2012 as they have been trying to find the subsequent targets to discover on the Moon. In partnership with Russia and greater than a dozen different nations and organizations, China is main the development of the Worldwide Lunar Analysis Station, which is meant to take form within the mid-2030s on the Moon’s south pole for scientific exploration and useful resource exploitation.
“Contributing to lunar science is a profound way for China to assert its potential role as a scientific powerhouse in the decades to come,” says Mitchell.
Liu says that his workforce has already began work to enhance the decision of the maps, and can produce regional maps of upper accuracy on the idea of scientific and engineering wants. Within the meantime, the finished atlas has been built-in right into a cloud platform known as the Digital Moon, and can ultimately grow to be out there to the worldwide analysis neighborhood.
