China has released this awesome new map of the Moon; the most detailed to date and at a scale of 1:2,500,000.
It is based on data from China’s Chang’e project, as well as other data, scientists from a number of institutes created the high resolution topographic map. It includes 12,341 impact craters, 81 impact basins, 17 rock types and 14 types of structures, all of which provide detailed information about the lunar surface, including its geology and evolution.
There are also special features in the map that include “the landing sites of all the previous landing exploration missions (i.e., Apollo, Luna, and Chang’e missions), locations of chronostratigraphic “Golden spikes” (Das Formation, Janssen Formation, Fra Mauro Formation, and Hevelius Formation), elevation peak and bottom of each quadrangle (elevation points), and geological contacts”.
According to the paper, “Geologic maps of the Moon provide comprehensive information about the geologicstrata, structural features, lithologies, and chronology of the lunar crustal surface, which reflect the evolution of lunar crust under igneous processes, catastrophic impacts, and volcanic activities.”
“As unprecedented integrative product of lunar exploration results, the 1:2,500,000-scale lunar geologic map will play important roles for the scientific study of the Moon and lunar exploration in the future. With 10 years of endeavors, the experience we learned from this lunar mapping project lays the foundation for mapping other planets”, they conclude.
The map was published by Science Bulletin on May 30, 2022.
