Chinese spacecraft ‘drills’ the dark side of the surface and finds an intriguing mystery deep inside – Metro World News Brazil

The Chinese space agency has also focused on lunar research for many years. And in 2019, they sent the Yutu-2 spacecraft to study, among other things, the dark side of the natural satellite.

This vehicle has tools capable of analyzing the depths of the moon without the need to drill its surface. It’s a way to see what’s under the soil of the rocky body we see every night in our sky.

The tool is called Lunar Penetration Radar (LPR), and according to Urban Tecno, it works by sending radio signals into the interior of the lunar surface.

This renders the response, a kind of echo that reverberates in the rocks, in a frequency mode that reveals the thickness of the lunar makeup.

Previously, in 2020, Chinese scientists managed to capture depths of about 40 meters. But now they have reached a depth of 300 metres, and found that there are five layers of different materials, each with a different thickness.

What is the secret of the lunar surface?

The Moon is a rocky body, but without the protective atmosphere found in our universe. We are the central axis of its orbit and are believed to have many similarities with Earth.

Now, this discovery reveals that the Moon has a volcanic past, as has often been thought.

“The data is consistent with a series of basaltic eruptions that occurred millions of years ago. The team believes that the decrease in thickness indicates that the rate of pyroclastic flow has decreased after each subsequent eruption.” This is consistent with the general view of volcanic activity on the Moon. As our satellite ages and cools, volcanoes are becoming increasingly rare,” reports IFL Science.
