After a long journey of more than 20 days, China's Chang 'e V not only successfully landed on the back of the moon, but also recovered 1700 grams of lunar soil. It can be said that "Chang 'e borrows land" is the peak of China's space development and the highest achievement of integrating China's space science and technology.
Chang 'e brought earth.
Chang 'e V landed on the moon in an unmanned state and successfully retrieved the lunar soil samples. This project is very complicated. The complication is that the landing site of Chang 'e V is essentially different from the landing site of the United States and the Soviet Union on the moon-on the back of the moon.
Why is it so difficult to land on the back of the moon? The reason lies in communication and uncertainty. In order to solve the communication problem, we also launched a relay satellite to solve the communication problem for Chang 'e V landing on the back of the moon. As for the uncertainty, no country has ever landed on the back of the moon, because the moon has always been facing the earth, and what is the situation on the back of the moon is still unknown to humans.
Communication problems are easy to solve, but the risk of uncertainty is great. The soil on the back of the moon is precious. The landing site of Chang 'e V is in the stormy ocean area of the moon. This area is actually a "new area" of the moon. Why is it a new field? In the past, both the Soviet Union and the United States collected soil samples from the moon, and the United States even collected more than 700 kilograms (only a few grams were given to China). But all of them were collected soil formed by the moon 3 billion years ago, lacking new soil formed after the moon operated for billions of years.
The lunar storm marine soil is the lunar soil formed in the past 654.38 billion years, and it is on the back of the moon. The lunar soil collected by China is essentially different from that collected by the Soviet Union and the United States, and it has more research value and scientific and technological value.
Why borrow soil?
Why did man go to the moon? On the one hand, it is the exploration of space, the world and universe we live in, and on the other hand, it is the way to find a way out for human development, which is the only way for us to reach a higher level in Gao Wenming.
The above paragraph can be completely ignored, because we humans don't have the ability to realize those dreams at present. What we need now is development, which needs energy and scientific and technological progress. What's on the moon? Helium 3 on the moon.
This is a new material recently discovered on the moon. The content of this helium 3 ore is extremely low on the earth, but it is extremely rich on the moon. This substance can participate in the nuclear fusion reactor reaction together with deuterium, releasing a lot of energy.
The energy released by 1 ton of lunar helium 3 is equivalent to that released by150,000 tons of oil.
This is a fairly clean energy source, which is stable, safe, environmentally friendly and high in energy. It can be said that the rapid development of human civilization in the future is absolutely inseparable from this primitive energy ore.
There is abundant lunar helium 3 on the moon, but everyone can only look at it. Landing on the moon to collect, transport and open it is simply too difficult. Is it true that even obtaining helium 3 samples on the moon can only be done by a few space powers, and China is the only country in the world that can do it so far?
We have obtained lunar soil, which is a very solid step in lunar research and a key link for us to lead the world in lunar research.
America is eager to get some soil samples.
America landed on the moon as early as 1970s. The Apollo program in the United States not only sent humans to the moon, but also obtained more than 700 kilograms of soil on the moon. In fact, the study of lunar soil in the United States is not worse than that in China. Their research on the moon is even far ahead of other countries in the world, including China.
However, the lunar soil brought back by Chang 'e V aroused strong interest in the United States. Although they didn't formally ask China to give some soil, judging from the attitude of American media, public opinion and NASA executives, they were actually quite eager to get the soil samples that China got from the moon this time.
Is it just because the United States wants to get the latest lunar soil data, so as to conduct space research and contribute to the dream of human space development? If everyone thinks so, it's all wet. The United States can be said to be troubled.
China's technological development in space can be described as high speed, and we have even "surpassed" the United States. In fact, in many fields of aerospace, China is far ahead of other countries in the world, even the United States. For example, this time Chang 'e V landed on the back of the moon. With the current scientific and technological capabilities, economic capabilities, remote sensing control, data transmission and so on, it is estimated that only China can do it.
The purpose of the United States to want lunar soil is actually very simple. It wants to study the latest lunar soil, soil, minerals, climate, geographical environment and so on. The United States is more eager to occupy the resources on the moon than any other country.
If the United States is allowed to restart the moon landing program, it will not only cost a lot of manpower and financial resources, but also delay for several years. Landing on the moon is not a simple year or two. By the time the United States gets ore samples from the moon, it is estimated that China has gone a long way to study the moon.
China's acquisition of lunar soil is a great progress in our space science and technology, and we have never conducted lunar research and development with any political or military purpose. As for the United States wanting our lunar soil samples, if it is for scientific and technological purposes, I believe China will give generously, but if it is for hegemonic purposes, I'm sorry, the people of China will not agree.
