New discovery of the moon appreciation: What is the mysterious "Chang'e Stone" hidden?

Produced | NetEase News

Introduction: Earlier this month, the National Space Administration and the National Atomic Energy Agency jointly released the latest scientific achievements of Chang'e 5: new minerals were found in the Moon Sun sample. stone".

This is the first new Moon Mineral Minerals discovered in my country, and it is also the sixth new lunar new mineral found in the world. As the major breakthrough results of Chinese celestial mineral research, the discovery of "Chang'e Stone" marks that my country has entered a new stage of developing space resources.

1. "Chang'e 5" returns to the earth to bring back a great gift

The "Chang'e 5" detector is developed by the National Aerospace Administration. It is the sixth task of China's lunar exploration project. The Long March 5 Rockets launched on January 24, 2020.

"Chang'e 5" returns from the moon

The Chinese lunar exploration project has planned a total of three stages of "detour, fall, and return". Compared with the previous few lunar exploration tasks, the biggest difference of "Chang'e 5" is to adopt moon soil and moon rock samples and bring them back, which are taken through the robotic arm table and drilling. Its specific engineering goal is three aspects: first to break through space sampling and return related technologies; secondly, the automatic sampling returns of the outer celestial body will be applied to the detection of celestial bodies such as comets; and finally for subsequent loads The monthly and deep space detection accumulation of technical talents.

Moon soil and Yueyan are a great sample to study comprehensive moon information. The reason is that the vacuum environment on the surface of the moon allows the soil and rocks to be stored steadily. Because the moon soil does not contain moisture and organic substances, the moon soil will not Condensed into pieces. Generally speaking, the soil is caused by the crushing of rock burst, but the sample that retrieves seems to break the cognition.

The place where the "Chang'e 5" landed on the moon was the youngest storm on the surface of the moon. The moon rock samples obtained through drilling were about 1.96 billion years. It is a basalt formed by the lunar volcanic eruption. It is very old. However, the rocks are young compared to the soil around these rocks. According to analysis, the soil samples retrieved by the "Chang'e V" are at least 1 billion years older than the rocks. The difference between these soils and rocks is huge and from other places. The results of the above analysis can be strongly proved that the geological (magma) activities of the moon lasted at least 1.96 billion years ago.

In the vacuum environment of the moon, the larger the number of meteorites seen on the surface, the longer the age of the region. According to this phenomenon, scientists have determined the youngest and oldest regions on the moon-Storm Ocean and Antarctic Etherken Basin. Month of life. The samples of these two regions will help further explore the mystery of the moon.

Second, the mysterious gift "Chang'e Stone"

The mainstream theory believes that the moon is separated from the earth, and most of the minerals on the moon can be found on the earth. Minerals refer to uniform solids that are naturally produced and the internal texture are arranged in an orderly manner, which is formed by geological effects. Its chemical composition must be expressed by chemical formulas. The so -called lunar minerals refer to the minerals on the moon, but the minerals found on the moon first. The minerals that are officially named "Chang'e Stone" are the sixth new minerals discovered by humans on the moon. my country is also the third country to discover lunar minerals after the United States and Russia.

Moon soil micro structure

The first five types of minerals are: "Almako Monthly Stone" (a kind of titanium mineral), "three -diagonal iron pest" (a kind of iron ore), "Jinghai Stone" (a kind of silicate Minerals) and "Yaoxi Yaoche" (a kind of silicate mineral), and the "natural 铈 CE" (unilateral form of 铈 element) discovered by Russia.

The sixth type of moon mineral "Chang'e Stone" was found in the Moon Xuanwu rock debris brought back by "Chang'e 5". The ideal chemical formula is (CA8Y) Fe (PO4) 7. The crystal structure belongs to the three -party crystal system. Landlinter, square quartz, meteorite iron and glass.

The earth currently has more than 5,000 kinds of minerals, but there are only a dozen types of the earth. The reasons for the increasing mineral types are related to the increasingly complicated chemical reactions caused by water, air, crustal movement and various biological effects on the earth. Relatively speaking, the moon is in a vacuum and dry environment, and there is no heat provided by geological activities. It interrupted a large number of chemical reactions. Therefore, the types of minerals on the moon are much scarce than the earth, and each new discovery is precious.

Because many substances have been stably preserved for billions of years. Through studying these minerals, the earth can be closer to the real situation of the Earth of the Moonic Moonic Lunar compared with the vicissitudes of the sea.

3. "Moon Development" creates a new planet of human beings

All the investment in the exploration of the moon is to obtain richer returns in future lunar development, and the future construction of the moon into a livable environment in the future is the most critical step.

Moon mineral mining imagination

The development of the moon cannot be separated from the important material of the moon soil. The moon soil is one of the richest resources on the moon. The large amount of ingredients in the moon soil have been proven to be of great significance for human survival and scientific research. Reduce the load and cost of the spacecraft, and even use the moon as a transit base. For example, in terms of energy, 3 -3 is considered to be the best raw material for future controlling nuclear fusion reactions and the best way to achieve sustainable energy.的 -3 is an important ingredient of solar wind. The thick layer of atmosphere on the earth makes it very scarce. However, because the moon has no atmosphere, it is blown by the sun wind all year round, and a large number of 氦-3 is stored. Exploring the content, distribution and mining of the 的 -3 on the moon has become an inevitable trend and main task for the current international deep space detection. The Chinese Academy of Sciences has made breakthroughs in the method of extraction of the "Chang'e-5" sample in the moon soil.

In addition, the moon has been proven to have a lot of solid water in North and North Pole. The research team in our country studied the moon soil sample carried by Chang'e V. After extracting the active ingredients as a catalyst, solid water and carbon dioxide were used as raw materials. It is superior to the performance of the surface of the earth's surface basalt catalytic components. The reason is that the surface of the ingredients in the soil often has rich microporous and vesicular structures. The surface area is large and the catalytic performance is good. In the catalytic reactions of synthetic hydrocarbons, higher efficiency has also been achieved.

These achievements also provide possibilities for the supply of fuel for human survival and rockets, and this technology will be verified at the "Tiangong No. 1" space station.

A large amount of solid water was found in the north and south poles of the moon

Conclusion:

my country has named the geographical names such as "Guanghan Palace", "Weaver Girl", and "River Drum" on the moon. There are more and more Chinese elements on the moon. The discovery and naming of "Chang'e Stone" marks that my country's exploration of the moon has reached a new stage. The gradual completeness of these technologies will make my country get closer and closer to the establishment of a moon base.
