Scientists have always speculated that there is a mantle under the moon's shell, just like the earth. However, 60 years of lunar exploration, including the American Apollo program, failed to provide evidence to prove this. Although there are clues, there is no direct evidence.
"Yutu" found olivine in the surface samples collected near the landing site. Like the earth's mantle, this green crystalline mineral can usually be found deep underground.
Further analysis shows that olivine does not come from the discovery site, but from the nearby crater with a diameter of 72 kilometers.
According to reports, there are more craters on the back of the moon than on the front of the earth, and meteor impact is likely to penetrate the lunar mantle and throw minerals to the surface.

What scientific discoveries did Yutu make in this lunar exploration? Please write down the information you collected.
/kloc-in the early morning of may 6, the international scientific magazine nature published the first batch of scientific achievements of Chang 'e IV. According to the data of visible light and near infrared spectrometer (VNIS) carried by Yutu-2, it is proved that there are deep lunar materials, mainly olivine and low calcium pyroxene, in the lunar soil of Chang 'e-4 landing area.

What scientific discoveries did Yutu make in this lunar exploration?
2019,65438+10.3, the "Jade Rabbit" was launched. It carried countless dreams of people and came to the beautiful moon. What's the secret of this magical and beautiful planet? "Jade Rabbit", also known as "Chang 'e IV", not only realized the idea of detecting the back of the moon, but also brought us many scientific discoveries! Today, we will solve the mystery! "Jade Rabbit" found that there is water on the moon, but it exists in the form of ice, which belongs to very advanced technology and is very magical. Yutu 2 lunar rover "stepped on the back of the moon" for the first time, leaving it on the lunar mantle material from the deep part of the moon. This provides direct evidence for solving the problem of detailed material composition of the lunar mantle that has puzzled scientists for a long time, and can help mankind to further understand the formation and evolution of the moon. Similar to the earth, the moon consists of an inner core, a mantle and an outer shell. Scientists infer that with the evolution of lunar rocks, lighter plagioclase components float to form the lunar crust, while heavier minerals such as olivine and pyroxene sink to form the lunar mantle. However, this inference about the composition of the lunar mantle has not been strongly confirmed so far. With the development of science and technology, various scientific secrets have been gradually uncovered. I believe that in the near future, our technology will be more advanced and we will know more and more knowledge. Knowledge needs to be discovered and created bit by bit, and we will be stronger and better in the future!

What scientific discoveries did Yutu make in this exploration?
The scientific discovery of Yutu in this exploration: Yutu lunar rover carried out 1 14m geological survey around C 1 crater, and obtained rich and precious lunar geological data. The results of many scientists' work based on these materials are published in the world's top scientific magazine Science. The data detected by the lunar radar carried by Yutu shows that the surface of Chang 'e-3 landing area is divided into at least 9 layers, indicating that there have been many geological processes there, which is of great significance for exploring the evolution history of lunar magma and its later transformation. This is the first time that scientific achievements have been published in top international academic journals since the implementation of the China Chang 'e lunar exploration project. Extended data:
Because of the great temperature difference between day and night on the moon, the temperature is as high as 150 degrees Celsius during the day and as low as-180 degrees Celsius at night. In order to adapt to the extreme environment, the "Yutu" lunar rover can withstand the temperature difference of 300 degrees Celsius by using the heat-conducting fluid loop, heat insulation components, cooling surface design, electric heater and isotope heat source. It takes more than 28 days for the moon to circle the earth, and the moon rotates for 28 days. This means that a day and night on the moon is equivalent to 28 days on the earth. The lowest temperature on the surface of the moon at night can be reduced to-180 degrees Celsius, and electronic equipment can't work at all. One night on the moon is equivalent to 14 days on the earth. Therefore, researchers designed a sleep mode for "Jade Rabbit"-working 14 days and "sleeping" 14 days.

What are the scientific findings of Yutu in this liquid level detection?
The breakthrough discovery of the "Jade Rabbit" lunar rover proves what scientists have been thinking for decades: the moon has a lunar mantle. Scientists have always speculated that there is a mantle under the moon's shell, just like the earth. However, 60 years of lunar exploration, including the American Apollo program, failed to provide evidence to prove this. Although there are clues, there is no direct evidence. During the first landing on the back of the moon in 20 191October 3, Yutu found olivine in the surface samples collected near the landing site. Like the earth's mantle, this green crystalline mineral can usually be found deep underground. Further analysis shows that olivine does not come from the discovery site, but from the nearby crater with a diameter of 72 kilometers. According to reports, there are more craters on the back of the moon than on the front of the earth, and meteor impact is likely to penetrate the lunar mantle and throw minerals to the surface. It is generally believed that the moon was once covered with lava. Lighter substances float to the surface to form the moon shell, while heavier substances sink to form the moon mantle and moon core. The new research results confirm this theory.
