Chang'e-5 has been on the "Fat Five" on November 24 since it began its lunar exploration journey, and it has been on for more than 20 days. It successfully completed a number of arduous tasks on December 17 and successfully returned from the moon by "digging" Earth. What is exciting is that the Chang'e 5 mission brought back a rare substance. 100 tons is enough for the earth to use for a year. As soon as the news came out, many countries wanted to explore the moon.
The soil brought back by Chang'e 5 is very unusual.
What China’s Chang'e 5 brought back this time is extremely precious lunar soil. This is the first time we humans have obtained lunar soil again after 44 years.
At the beginning, most of the lunar samples mined by the United States and the Soviet Union came from the lunar sea area in the middle and low latitudes of the front of the moon. The formation age was 3.2-4.6 billion years. It was also through the analysis of the US and Soviet samples that the moon was established at 4.6 billion years. About the evolutionary history.
is different from the United States and the Soviet Union. The landing site chosen by Chang'e 5 is the northern area of Mount Rumke on the moon. It is located in a 1300-meter-high volcanic group in the northern part of the storm ocean. The craters distributed here are about Twenty is a relatively young area, with an age of approximately 1.2 to 1.5 billion.
This also determines that the collected soil is “younger” compared to the samples from the US and the Soviet Union, which can fill in the gaps in the study of lunar history. Therefore, the lunar samples brought back by Chang'e-5 this time have made many countries express their hope to bring these samples. The soil is shared, which shows that the lunar samples brought back this time are very attractive. What can
do?
After preliminary measurements, the Chang'e-5 mission collected a total of 1731 grams of lunar samples. For such precious lunar soil, some people have been asking whether it is used to grow vegetables.
First of all, the chemical composition of lunar soil is very complex. Through research, it is found that there are natural mineral particles such as silver, iron, lead, zinc, tin, copper, manganese, silicon, aluminum, calcium, magnesium, rhenium, etc. There are few ingredients, but there are many kinds, up to more than 20 kinds, and it also contains a lot of rare gases.
On the other hand, the soil composition on the earth is composed of various granular minerals, organic matter, moisture, air, microorganisms, etc., so the soil on the moon must not be used to grow vegetables, if it is used directly If you grow vegetables, you can't grow anything. After all, the lunar soil is very dry and lacks the necessary conditions such as water and organic nutrients for plant growth.
However, the lunar soil is of great significance for the composition analysis of the sampling area, that is, the study of rocks, minerals and chemical composition. This will provide very valuable data support for mankind to further understand the moon in a comprehensive way, because the current research results know that this area was formed in a relatively short time and is relatively "young", and it has great significance in studying the lunar volcanic activity and evolution history. Meaning, can help humans better understand the formation process of the moon.
More importantly, the helium-3 resources found in the lunar soil are very rich.
It is understood that the lunar soil brought back from the moon was found to contain a rare energy-helium-3, which is a colorless and odorless helium isotope gas, which is recognized worldwide as the most ideal nuclear fusion reaction A raw material that has the characteristics of high efficiency, cleanliness, safety, and cheapness.
According to scientific statistics, 10 tons of helium-3 can meet all of the country's energy demand in one year, and 100 tons of helium-3 can provide the world's total energy for one year. However, the reserves of helium-3 on the earth are very small, and the study of the moon has found that the shallow layer of the lunar crust is rich in helium-3 resources, especially in the storm ocean area, which may contain millions Tons of helium-3 is enough for humans to use for tens of thousands of years, and is the ultimate energy source for the future of mankind.
helium-3 is a nuclear fusion fuel.
As we all know, the development of science and technology nowadays makes human beings consume energyIt is very big, and the problem of finding new energy is imminent. Nuclear energy has always been considered an ideal energy source for humans. It is limited by the level of technology. Nowadays nuclear fusion is always accompanied by neutron radiation, because neutrons are not charged and have strong penetrating power. Taking away a large amount of energy generated by nuclear fusion, and also producing various radioactive materials, the current nuclear fusion reaction is difficult to control and very dangerous.
Therefore, human beings have set their sights on controllable nuclear fusion , using the isotope of helium helium-3, because the nucleus of helium-3 contains only one neutron and two protons, which is relatively stable. Helium-3 is regarded as controllable The fuel for nuclear fusion will produce huge energy without generating neutron radiation. Therefore, it can be said that helium-3 is a near-perfect energy material and has become the most ideal fuel for controlled nuclear fusion in the future.
In short, if the resources on the moon can be successfully developed, then the resource crisis facing the earth will be solved. It is precisely because of this that many countries have made the moon an exploration target.
