MORE THAN 100,000 NEW CRATERS FOUND ON MOON WITH THE HELP OF CHINA’S CHANG’E LUNAR PROBES

About 109,000 previously unrecognized impact craters on the moon using machine learning techniques have been discovered by an international team of researchers. The researchers from Jilin University had published a study in their journal called 'Nature Communications'. The most prominent moon's surface feature is the impact craters; they cover most of the lunar surface and hide a history of solar events. 

With conventional automated detection techniques, unusual and highly damaged impact craters that may have formed in the early stages are usually difficult to locate. Researchers applied a transfer learning approach to accurately classify craters and predict their age, and equipped a deep neural network with data from previously identified craters, reports the Xinhua news agency.

Researchers found 109,956 new impact craters by integrating the data obtained by China's Chang'e-1 and Chang'e-2 lunar probes. The ages of 18,996 newly discovered craters greater than 8 km in diameter were also measured.

Meanwhile, for the mid and low-latitude areas of the moon, researchers have set up a new lunar impact crater database.

One of the researchers, Yang Chen of Jilin University, said the lunar crater database is of great significance to the moon's scientific studies.

"The adopted strategy can be applied to assist crater studies, generating reliable suggestions for planetary research," Mr. Chen said.

This model of the study was extended to the discovery of small impact craters at the landing site of the Chang'e-5 probe, he added.
