What does it mean that we go to the moon to dig in the earth?

This sentence contains two meanings, one is right, and the other is just ridicule!

Going to the moon to dig for dirt is simply an impossible task for ordinary people! Therefore, its difficulty becomes a tongue of ridicule. The extended meaning is: you are amazing, why don't you go to the moon to dig the soil!

I know I can't do it, but I want to do it. Faced with difficulties, broke through many obstacles, and showed perseverance. "Hey, let's dig up the dirt on the moon! ”

That's rightEven if there are unknown difficulties ahead, they can't stop me from moving forward!

The opposite is,Forget it, don't look at you, if there is a backstage, I still want to save the world!

Today, November 24, the Chang'e-5 probe was launched with the aim of collecting about two kilograms of lunar soil and returning it to Earth, where it will help advance our understanding of the moon's volcanic activity and evolution.

Think too much. It's just to tease you, to talk. Wish.

It's just a joke, just to tease you, to talk about it.

1. For research.

Because there is no air on the moon, all kinds of ray particles that fall on the moon, as well as meteorites, can be stored for a long time. Therefore, there is a lot of very empty and precious information left on the moon, not only for the study of the moon itself, but also for the study of solar activity, and even for the study of the ceiling guessing ball.

2. For helium-3

Helium-3 is an important nuclear fusion material, and the energy produced by thermonuclear fusion of 1 ton of helium-3 is equivalent to 15 million tons of fossil fuel. It is estimated that only 10 tons of helium-3 will be needed to meet China's annual energy consumption. And the most important thing is that there are no neutrons in thermonuclear reactors using helium-3, which means that helium-3 is used as an energy source and does not produce radiation, while the moon contains a large amount of helium-3.

Thinking about the fact that some countries are now in trouble for oil, the importance of helium-3 is self-evident.

3. For a longer future.

Human beings have always imagined traveling in space, and the moon is the first step for human beings to go to space, after all, if you can grow some vegetables and raise some pigs on the moon, and use the moon as a transit station, it will be easier to go farther into space.

1. Make up for the gaps.

Although the United States and the former Soviet Union have brought back a large number of lunar soils, these samples are still very limited in understanding the moon. Most of them come from the lunar sea region in the middle and low latitudes of the front of the moon, and the formation age is concentrated between 4.2 and 3.2 billion years ago, which is equivalent to the "childhood" period of the moon.

In fact, in the 4.5 billion years of the Moon's history, the time period of 10-3 billion years is almost completely blank. This is the significance of the Chang'e-5 mission. Chang'e-5 will land in the Rumke Mountains, a 70-kilometer-diameter hill near the bottom of the Stormy Ocean, the moon's largest lunar sea, far from --- Apollo and Luna's sampling areas, rich in volcanic activity and rock types unlike previous samples.

Therefore, in this volcanic area, Chang'e-5 may collect samples that were formed between 1 billion and 2 billion years ago, which will fill the biggest gap in the geological dating and dating of the moon.

2. Verify the lunar escape capability.

The arrival of China's spacecraft on the moon is nothing new, but how to ignite from the moon and return to the earth is a difficult action. After E-5 flies to the moon, the orbiter and returner will remain in lunar orbit, and the lander and ascender will separate and land on the moon. At the end of the sampling mission, the ascender will use the lander as a launch platform to ignite and launch away from the lunar surface.

After the ascender successfully docks with the returner, it must escape the gravitational pull of the moon, which must first reach the moon's first cosmic velocity of kilometers and seconds. In order to escape the gravitational pull of the moon and fly to the earth, it is necessary to reach the escape velocity of the moon in kilometers and seconds. This is the data that we guess needs to get into the base or step verification.

1. Lunar soil, that is, the soil of the moon, contains great scientific value for the people of the earth. In order to dig for the moon, the main aerospace country Xiang held the pure family very hard.

2. The Soviet Luna 16 probe retrieved a small sample of 101 grams from the moon, while the Luna 20 probe and the Luna 24 probe collected samples of 55 grams and 170 grams respectively.

From July to December 1972, the United States carried out seven manned missions to the moon through the Apollo 11 to Apollo 17 manned spacecraft, except for Apollo 13 which returned halfway due to a malfunction, the remaining six spacecraft completed the moon landing, successfully sent 12 astronauts to the moon, and brought back a total of about 382 kilograms of lunar soil and lunar rock samples.

4. The goal this time is to bring back about 2 kilograms of lunar soil. After demonstration, the amount of 2 kg is not small, and it is achievable in engineering. But as an assessment of this mission, the goal is to sample and return. When a sample is collected and returned to Earth, it is a success.

5. The Moon is the only natural satellite of the Earth, and it is also the strategic commanding heights of the Earth. Hu Hao, chief designer of the third phase of China's lunar exploration program, believes that because the moon has its unique conditions, its location, environment, and resources are very unique, it is of great significance not only for the subsequent development of space technology and scientific understanding, but also for the subsequent development of economic and social construction.
