China's lunar rover makes an unexpected discovery in the far side of the moon

As was the first mission that successfully arrived in the far part of the month it was almost expected that Chang & # 39; e 4 of China made some fascinating discoveries. However, the mission missed the mission that the mission was also accomplished.

In research published in the journal Nature on May 16, scientists from the National Astronomical Observatories of the Chinese Academy of Sciences show the composition of the lunar surface in The South Pole-Aitken Basin is a small difference in what They expect.

A fundamental theory posits the moon is not too cold and dead now. Instead it is likely to start as a giant, molten marble full of magma oceans. These oceans are gradually chilled, depositing heavy minerals such as green-colored olivine or deep calcium pyroxene in the deeper lunar mantle. Lower dense minerals float on top thus giving the moon a series of obvious geological layers such as a cosmic onion. The crust, the highest layer, consists mostly of aluminum silicate or plagioclase. "Understanding the composition of the lunar coat is critical for testing if a magma of ocean exists, as recorded," co-author Li Chunlai, in a statement. "It also helps advance our understanding of the thermal and magmatic evolution of the moon."

Understanding the composition of the mantle gives planetary scientists a greater insight into how interiors can be grown by other planetary bodies – including Earth.

Chang & # 39; e 4's path originally reached the Von Kármán Crater, located on the floor of the South Pole-Aitken Basin, back in January. Then the lander sent a rover, Yutu-2, fitted with a spectrometer measuring the light. By studying the illuminated light from the surface while the rover was combined with Von Kármán, scientists discovered minerals and referred to their chemical composition. Instead of seeing plagioclase, the rover saw the dominance of olivine and pyroxene.

Because these elements are expected to be deeper in the mantle, the authors indicate that they are released from an event caused by a meteoric attraction over the moon. The rover reflects at about 72 kilometers of the Finsen Crater, so minerals can be sprayed over the surface to create that crater.

Even though NASA's Apollo missions crossed the moon and Russia made an effort to capture lunar samples in the 1970s, there was no study of the end of the month previously . Making the mission of China more important, but due to the complexities of studying the minerals of the moon on a planet with hundreds of thousands of kilometers away, additional work is required to gather a more complete understanding in the composition of the mantle.
