To this end, human beings actively explore other planets. At the end of 2020, the Chang 'e V spacecraft independently developed by China successfully landed on the moon. After routine inspection, Chang 'e V began the task of collecting soil. According to reports, the soil brought back by Chang 'e V this time reached 2 kg.
When Americans learned that China had made great progress, they said there was nothing they could do. They sent a request to China Space Agency, hoping that we could share lunar soil and research data. But strangely, the United States has 382 kilograms of lunar soil. Why does the United States still want Chang 'e after she brought it back?
NASA is called "National Aeronautics and Space Administration". It has published a data: the Apollo spacecraft of the United States successfully landed on the moon six times, and one * * * moved back to Earth with 382 kilograms of lunar soil and more than 2,000 moon samples. Most of these precious treasures from the moon are kept in Houston Space Center, where NASA has established a lunar laboratory.
Americans cut and study things on the moon in the laboratory, plus things on the moon found on the earth. Now NASA conservatively estimates that there are more than100000 moon samples. It can be said that the United States is the country that knows the moon best in the world.
The lunar receiving laboratory covers an area of 1800 square meters, almost all of which are sterile warehouses and laboratories. Moon samples are kept in containers filled with nitrogen. Every scientist should wear rubber gloves to prevent pollution when he wants to touch them.
1979, the United States established a lunar sample laboratory with an area of 1300 square meters, and then stored most of the lunar samples in this new laboratory. Later, in order to prevent the risk of sample loss, the United States decided to put some moon samples in the laboratory in New Mexico. In 20 19, NASA dismantled the lunar receiving laboratory for unknown reasons.
At the beginning of studying lunar rock samples, American scientists were very afraid of these experiments from outer space. They not only isolated the astronauts, but also closed the moon samples for inspection. However, after more than half a century of observation and research, they found that there were super bacteria or super viruses on the moon, so American scientists relaxed their vigilance and began to carry the moon rocks by hand. The present American moon rock specimens must be covered with dander and fingerprints of American scientists.
In a word, the United States is definitely ahead of the world in the study of the moon.
After all, the United States has studied the moon for decades. From the research information revealed by Apollo, we can also see many interesting things. For example, in a slice named 10020, we can see that the moon rocks are rich in magnesium and iron, which will only form after volcanic eruption.
Of course, it also contains silicon. If geologists come to see it, they may get more different things.
Apollo program is the main plan of American lunar exploration, and the main plan of American lunar exploration is to collect lunar soil. In order to better complete the lunar soil collection plan, NASA will train astronauts to collect specimens after wearing spacesuits on the earth, which is also to make them better and faster in the collection work.
When they reach the moon, these astronauts will drive a lunar rover to collect rocks and soil within several kilometers of Fiona Fang, and then put things into bags. These actions will be recorded in the video.
The reason why I have described so many achievements in American lunar exploration is to tell you one thing, that is, Americans have studied the moon far more than other countries in the world. Then, after Chang 'e V landed on the moon, why did the United States ask China for soil? There are several reasons.
First, Apollo's lunar exploration has limitations. Since Apollo 15, Americans have had an advanced lunar rover and don't have to walk. They can travel more than ten kilometers around the moon to collect the soil of the moon, but for the moon, this ten kilometers may be no different from one meter and two meters. The specimens collected by American scientists can be said to be equivalent to spinning in place.
Moreover, due to the limitation of technology, Americans almost chose the same location for six moon landings, so they explored loneliness. This situation continued until the end of the Apollo program, and nothing changed. Therefore, the Apollo program left great regret for American lunar exploration.
The areas where the United States and the Soviet Union explored the moon are located in the low latitudes of the moon, commonly known as the Moon Sea, which was formed about three or four billion years ago. It is precisely because of the exploration of these soils that people think that the mature age of the moon should be 4.5 billion years ago, and its age should be about 60 million years to/kloc-0.0 billion years after the formation of the solar system.
In fact, the soil found on the surface of this moon has almost the same data. The soil research collected by Apollo in the United States shows that the traces of volcanic activity on the moon should be 3.5 billion years ago, but they estimate that there are volcanic rocks formed in other places one to two billion years ago.
But unfortunately, they haven't enough evidence to prove their guess. After all, neither the United States nor the Soviet Union has been to other parts of the moon.
This embarrassment lasted until Chang 'e V landed. The landing area chosen by Chang 'e V in China was near Lunke Mountain on the moon. /kloc-There was a huge volcanic eruption in this place 0/300 million years ago, so the rocks and soil collected in China will be younger.
If the soil brought back by Chang 'e V can prove this, it will be enough to rewrite the history of the whole moon. It is precisely because the moon specimens collected by the United States are all the same, and they lack this new specimen from China, so they urgently need the new soil specimen collected by Chang 'e V in China.
The second reason why the United States wants the soil collected by Chang 'e is to explore the mineral resources of the moon. The moon is a star formed hundreds of millions of years ago, so there must be many rare elements in it. For example, ilmenite was found in samples extracted from Yuehai, and rare earth was found in Kripke rocks, and so on. So scientists began to think about the moon. It is possible that the extremely scarce resources on the earth may be everywhere on the moon.
So what is Kripke Rock? This is a special kind of rock on the moon with a brown glass surface. Now most people in the scientific community believe that this is the legacy of a volcano hitting the moon hundreds of millions of years ago. At that time, it was melted, deteriorated and cooled by ultra-high temperature impact temperature, and many elements in it were energy elements that human beings were constantly exploring.
The reason why Americans attach so much importance to the soil brought back by Chang 'e V may be that they want to study helium 3 in the soil, which is also the fundamental resource for the United States to dominate the earth and carve up the moon.
Helium -3 is an essential element for human beings to build nuclear reactors. Because helium -3 has no neutrons, the nuclear reactor built on it will not produce any nuclear radiation. It may be the cleanest nuclear resource on earth and will replace oil.
Scientists have shown that the existence of helium 3 on the moon may be enough for people on earth to use for about 1 10,000 years. How much convenience will clean resources provide to the earth in 10 thousand years? Moreover, if helium 3 is used as space fuel, it can make spacecraft reach Mars, Saturn and other galaxies in a very short time, so its importance is all-round.
But unfortunately, there are only a few hundred kilograms of helium 3 on the earth, which can't meet the needs of all mankind at all. Therefore, the lunar soil brought back by Chang 'e V has brought new hope to scientists, who are likely to find a new future here.
In fact, the United States has long known the existence of helium 3 and has been constantly looking for it. Since the last century, the United States has established a space alliance to exclude China and Russia. The purpose of the United States is very simple, that is, to monopolize helium 3 and achieve the purpose of dividing up the moon. If this powerful element is controlled by the United States, the day when it will dominate the earth will come soon.
Fortunately, China is very powerful. Under the blockade of the United States, we have developed dozens of patents for landing on the moon. Through the wisdom and efforts of our people, we finally completed the moon landing with Chang 'e V.
The two kilograms of new moon soil brought back this time is too precious for Americans to get for nothing. On the other hand, for the development of the whole world, it is estimated that there is a high probability that China will release relevant data after the study is completed.
