Chinese astronomers have created a detailed geological map of the Moon

Chinese astronomers have presented the new most detailed geological map of the entire surface of the Moon at a scale of 1:2,500,000, which was created on the basis of data collected by automatic devices from different countries. It is assumed that the map will help in further exploration of the Moon and the choice of landing sites for future spacecraft, as well as be useful for popularizing science. The full version of the map is available on the website of the National Space Science Center of the Chinese Academy of Sciences.

 

Since the 1990s, the exploration of the Moon has entered a new turbulent phase, during which about 20 spacecraft from different countries, including China, India and Japan, were launched to the Earth's natural satellite. Thanks to this, scientists have obtained huge amounts of data on the morphology and composition of the Moon's surface and its internal structure, which makes it possible to significantly advance in understanding the formation and evolution of the Moon. Periodically updated geological maps of the Moon help to structure the information. They contain information about geological strata, structural features, lithology and age of various parts of the Moon's surface, which reflect the evolution of the lunar crust under conditions of magmatic processes, impacts and volcanic activity.

 

On June 15, 2022, a group of scientists from various institutes of the People's Republic of China, led by Jinzhu Ji from the Center for Lunar and Planetary Research of the Chinese Academy of Sciences, presented a new global geological map of the Moon at a scale of 1:2,500,000, which has become more informative compared to the previous version created by the US Geological Survey.

 

The new map was created taking into account all the data collected at the moment by automatic devices of observations of the Moon and is compatible with the map created by the US Geological Survey. It includes 12,341 craters, 81 impact basins and 17 types of rocks and is based on the fact that the evolution of the geological elements of the Moon must be considered from a dynamic point of view, highlighting endogenous or exogenous processes.

 

The map was created in the Mollweide projection, the stereographic projections of the north and south poles of the Moon are shown separately. Scientists expect that the map will help in further exploration of the Moon and the selection of landing sites for future spacecraft. In addition, the card can be used free of charge for non-commercial purposes, including the popularization of science.
