Can people really live on the moon?

A few days ago, some media reported that China had the ability to put a man on the moon. "That's half right," Ouyang Ziyuan said. "At present, China can indeed land a man on the moon, but it can only provide a one-way ticket. In other words, you can send it up but you can't bring it back. "

He explained that sending astronauts into the sky is not only to add one or two people, but also to provide astronauts with daily necessities on the moon. A load of 30 tons is definitely necessary. At present, the United States can only accept 8 tons of load.

Regarding people's dream of living on the moon, Ouyang said: "People can never immigrate to the moon, it's too difficult!" He pointed out that scientists can't "copy" the earth's environment on the moon, which will encounter great risks. It is more reasonable to pin the hope of "creating a second earth home" on Mars.

Answer the second question first:

② Natural conditions on the surface of the moon?

There is no atmosphere on the surface of the moon, but there are a certain amount of free hydrogen, sodium, magnesium and other elements in the space dozens of centimeters on the surface of the moon, which makes the pressure in this space 3 to 4 orders of magnitude higher than that in the general interplanetary space, reaching 0.000000 1Pa (note: the pressure on the surface of the earth is 100000Pa). At the same time, because there is no influence of atmospheric scattering,

Surface temperature near the equator of the moon (note: it is surface radiant heat, not air temperature, and there is no atmosphere on the surface of the moon): it exceeds 120 degrees Celsius during the day and drops to-180 degrees Celsius at night.

Autobiography of the Moon is 680 hours a week, which is equivalent to 28 days on Earth. In other words, on the moon, you can always see the sun for at most 14 days. Ha ha.

There is no liquid water on the moon surface. As for whether there is water ice, the scientific community is still exploring and studying. The lunar soil with a surface thickness of several centimeters was formed when meteorites hit the rocks on the surface of the moon (different from the soil on the earth). Beneath the thin soil is very hard basalt.

There is no known life form.

That's about it.

Then answer the third question:

(3) What are the basic conditions for human survival on the moon?

Human survival needs air with certain pressure, clean water, food, energy (temperature) and so on. None of the existing conditions on the moon (as shown in question 2) can meet the requirements of human survival without the transformation and processing of human science and technology.

Answer the fourth question again:

(4) If you want to live on the moon, what other living conditions do humans need to create?

As mentioned in question 3, in order to survive on the moon, all basic living conditions must be artificially created, such as air with certain pressure, clean water, food, energy (temperature) and so on.

Now we can answer the question of 1:

(1) What conditions should be met to establish a lunar base?

The base must first have energy, make air and water, and keep the temperature constant. Plants need energy to grow. Without energy, all human activities cannot be carried out. There is enough solar energy available on the moon. In addition, there is a substance called helium 3 in the lunar soil, which is a very high-quality nuclear fuel.

Human survival needs air, and the lunar soil contains certain oxides, which can be used to make oxygen after decomposition. Unfortunately, there is no raw material for making nitrogen on the moon. At present, there are two solutions in the scientific community: 1 replacing nitrogen with helium. The moon is rich in helium, which is harmful to human health. There is no technical problem in transporting from the earth, but the cost is extremely high.

Take water as an example. The recent detector results show that there is ice in a few places on the moon, and heating can form water. Another method is to use the abundant hydrogen and oxygen elements on the moon to synthesize water, which is very expensive.

There are a lot of mineral elements needed by plants in the soil and rocks on the moon. Using the existing soilless culture technology, plants can grow under the above conditions. Just don't forget to bring plant seeds when you go to the moon.

The lunar base should have the functions of production, life and scientific research, and should be self-sufficient to the maximum extent. But the building materials needed for the initial construction of the base must be brought from the earth (because there is no one on the moon).

There is no earthquake on the moon, but be careful. From time to time, meteorites will fall from the sky and break the roof.
