After digging soil on the moon, how did the moon landing machine take the soil from the moon?

At 4:30 a.m. Beijing time on November 24, 2020, the Chang'e-5 probe was successfully launched at the Wenchang Launch Center in China.

The Chang'e-5 probe from launch to return is fully automatic, so this also increases the difficulty of the Chang'e-5 probe project, after a week, the Chang'e-5 probe is also about to complete the goal of soil mining, but after the completion of soil mining, it does not mean that the task of the Chang'e-5 probe has been completed.

After the completion of the soil mining, the Chang'e-5 probe only achieved half of the mission, and finally needs to take off and return to the moon through the ascender, the difficulty of this task is also very large, because after the Chang'e-5 probe is quarried, it needs to carry out unmanned rendezvous and docking with the returner flying around the moon, and then quickly fall off the lunar surface through the accelerator to return to China, and then need to return to the correct orbital position and enter the atmosphere, so that the whole process can be regarded as the official end of the lunar exploration mission.

After the Chang'e-5 probe completes the exploration of the moon, the task of returning to the earth is really difficult, because the Chang'e-5 probe has to carry out unmanned docking with the returning vehicle after mining the soil, and no mistake is allowed in a single step, because whether it is the speed of the Chang'e-5 probe or the spacecraft or the speed of the moon, it is not the same, so this challenge is also extremely arduous. If the Chang'e-5 probe is not able to complete the docking work, it means that the lunar exploration project has not been successful.

We have made the most basic preparations for human beings to explore more distant planets in the future, after all, in the solar system, we have not yet found a suitable planet. Moreover, this is the third visit to the moon after the United States and the Soviet Union. This moon landing not only shows that we have made a big breakthrough in the field of space, but also shows that we can provide better space science and technology support to other countries.

Especially when the Russian space station was dismantled, now only ours is left in the air.

Orders were given by the command staff on Earth, and the moon landing machine, after receiving the order, began to carry out excavation operations.

This machine is actually using high-tech products to take the soil on the moon, not artificially.

It is through the lunar robot to collect lunar soil samples, which also requires cutting-edge technology to complete the operation, which also means that China's exploration of space is one step closer.

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 lunar positive plane, and their 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 between 10 and 3 billion years is almost completely blank. This is the significance of the Chang'e-5 mission. Chang'e-5 will land in Mount Lumke, a 70-kilometer-diameter hill near the bottom ---of the Moon's largest lunar sea, the Storm Ocean, far from the Apollo and Luna's starvation 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. That's the data we need to be further validated.

Bringing soil from the moon back to Earth is one of the main goals of the Chang'e-5 lunar exploration. By bringing the acquired soil back to Earth, it is important to use the resources of the Moon and establish a base on the Moon by studying the lunar soil, not only to understand the age of the Moon, but also to speculate on some geological activities on the Moon based on the Moon's soil, and to be able to detect the composition of the Moon's soil. Therefore, the soil brought back from the moon can be said to be priceless and extremely rare.

3. Understand and study the sun. Since the Moon is different from the Earth, the Moon is not protected by the Earth's atmosphere, so some activities of the Sun can directly act on the Moon, so by studying the soil of the Moon, we can have a study on the changes in the Sun's activities.

What else do you think the soil of the moon is for?

There are still many practical uses, and it is very helpful to analyze the soil composition of the moon and use it in some agricultural or scientific and technological research directions.

You can study the soil on the moon, the surface environment on the moon, and so on.

It is to allow our country to study some things on the moon, and at the same time we can also understand the moon better, which is also a great breakthrough for our country, which is very meaningful.

The success of lunar soil is a demonstration of China's aerospace strength, and lunar soil can help scientists further explore lunar materials and develop new uses.

First, the spacecraft is launched from the earth with a carrier rocket to the Earth-Moon transfer orbit, the spacecraft engine adjusts its attitude to slow down, and then is captured by the moon's gravity, and the spacecraft begins to fly around the moon. Photovoltaic panels, start the operation, including lunar sampling, and after all the work is completed, the lander ignites the engine and begins to get rid of the lunar gravity and dock with the circumlunar orbit module, accelerate to the moon-to-earth transfer orbit into the circum-earth orbit, adjust the attitude, slow down, and return the capsule into the atmosphere to the landing site to release the parachute and land safely. The rest is no longer in the text.

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, major spacefaring countries are fighting.

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 382,000 acres 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 follow-up development of aerospace technology and scientific understanding, but also for the follow-up development of economic and social construction.
