Scientists have informed us that lunar craters are formed when meteorites and asteroids bump into the lunar surface. These lunar craters disclose many mysteries about the history of the solar system just like fossils on earth. They reveal details about how these planets have been formed. Now Chinese scientists have found that there might be around 100000 lunar craters on the moon. They have used artificial intelligence to get an estimate of total lunar craters on the natural satellite. This figure is far more than 9137, the number of lunar craters on the moon, which have been identified by the International Astronomical Union. The agency has estimated the number with the help of elevation details and images. Chinese experts have used the data of 7895 earlier detected craters and 1411 craters, which have been found more recently in their study. They have used machine learning to train a deep neural set-up. The findings of the study have been released in the journal called Nature Communications.
Scientists have looked at the data, which have been collected by China’s first and the second orbiters, Chang’e 1 and Chang’e 2. After a close analysis, they have found around 109956 new lunar craters on the moon. These two uncrewed spacecraft have been launched in 2007 and 2010 respectively. As per the experts, impact craters are the diagnostic trait of the lunar surface. It is quite different from the earth’s surface, said the experts. The lead author of the study Chen yang has said that it is quite hard to identify the history of the earth being affected by comets or asteroids smashing into it over the past 14 billion years. The author has said that the moon and earth have been affected by the same impactor population over the years. However, massive lunar craters have gone through minimal degradation in the past billion years. On the other hand, the lunar surface of the moon does not have an atmosphere, water, and tectonic plate activity, which are responsible for eroding the earth’s surface. Due to these three forces, the most recent meteor impact cannot be traced. Due to the lack of these three forces, every impact on the lunar surface of the moon is going to be there forever. The dusty footsteps of the astronauts during the Apollo mission, who have walked on the moon, are still present on the moon.
The Lunar Planetary Institute has reported that nearly 80 percent of the earth’s plane is less than 200 million years old. Whereas 99 percent of the moon’s lunar surface is more than 3 billion years old. Experts have said that that the age of a bigger crater can be calculated by identifying how many small craters are there inside it. This is not the first study, which has used machine learning to identify the number of lunar craters. China is the third country in the world that has successfully collected lunar rocks from the moon. In mid-December, China’s ambitious unmanned spacecraft Chang’e 5 has come back from the moon, carrying the nation’s first sample from the natural satellite.
