On the evening of December 3, 2020, the Chang'e-5 ascender "farewell" to the lander, carrying about 2 kilograms of lunar soil to fly from the moon to the earth, and will be precious at 1:59 am on December 17 Brought back 2 kilograms of lunar soil.
Many people don't know exactly what the lunar soil is, so they will be full of expectations for the reveal of the lunar soil. In order to enable everyone to have a preliminary understanding of Lunar Soil, I deliberately checked relevant information. Next, I will disclose to you the relevant information about the lunar soil that I have read from the data. The so-called "lunar soil" of
is actually a layer of fine particles with a diameter of less than 1 mm but with a viscous particle covering the surface of the moon . The thickness of the lunar soil on the moon varies from place to place, about 5-6 meters in thick places, and only a few centimeters in thin places.
scientific research found that: lunar soil is rich in helium-3. According to scientific estimates, the total amount of helium-3 resources in the lunar soil can reach 1 million to 5 million tons, while the content of helium-3 on the earth's surface is only about 500 kg. Therefore, the total amount of helium-3 on the moon can reach the earth. On the surface, the total amount of helium-3 is a million times, or even ten million times.
Helium-3 is a colorless and odorless gas, and its extraction process is extremely complicated. Under normal circumstances, people first need to heat the lunar soil to over 700 degrees Celsius, and then helium-3 can be extracted from the lunar soil. According to
, helium-3 is a clean, safe and efficient nuclear fusion power generation fuel. If helium-3 is used for nuclear fusion reaction power generation, then only 1 ton of helium-3 is required to generate electricity, which can meet the world's electricity demand for one year. This shows that if the lunar soil can be used properly, we don't have to worry about the depletion of the earth's resources. In addition to helium-3, lunar soil also contains metal elements such as iron, calcium, magnesium, and natural metals such as cerium, rhenium, and zinc. It is a rare soil rich in metal elements.
So, does the sandy soil of the lunar soil contain the nutrients needed for plant growth? Can lunar soil be used to grow vegetables or other crops?
According to research findings, lunar soil does not contain any nutrients required for plant growth. As far as plant growth is concerned, it belongs to "barren soil" and therefore cannot be used to grow vegetables or to grow other crops. From the perspective of planting alone, lunar soil does not seem to have any value.
However, according to the US Newsweek website on January 22, 2020, European Space Agency intends to use lunar soil simulants to make oxygen. If this experiment is successful, people can use real lunar soil to make oxygen on the moon. Once there is oxygen on the moon, people have hope to settle and live on the moon.
Actually, the use of lunar soil to produce oxygen is not a fantasy. According to measurements, the lunar soil contains 40%-45% of oxygen. However, as far as the existing technology is concerned, the oxygen in the lunar soil cannot be used directly by people. Because the oxygen in the lunar soil is chemically combined with the lunar soil. To extract these oxygen from the lunar soil, the lunar soil must be processed with the help of molten salt electrolysis technology.
Although there is no oxygen on the moon that can be directly used by people, and there is no soil that can grow vegetables or other crops, with the development of science and technology, all these problems may be solved. Once these problems are solved, people Will be able to realize the dream of settling on the moon.
