Chang e 5 is about to end its space journey, what effective information does its space journey provi

Chang'e-5, developed by the China Academy of Space Technology, is a lunar probe in the third phase of China's lunar exploration program. It was successfully launched on November 24 this year and entered the scheduled orbit, and on December 17 she successfully completed her mission and returned to Earth. <>

In the context of the development of lunar resources and the establishment of lunar base stations have become more and more a global trend, China's lunar exploration program officially began in 2004, also known as the "Chang'e Project". It is divided into three stages, namely: "unmanned lunar exploration" stage, "manned lunar landing", "establishment of a lunar base" stage.

Since its inception in 2004, China's lunar exploration program has been going on for more than 15 years, during which time it has launched Chang'e-12345. The Chang'e-5 satellite can be said to be the final battle of China's lunar exploration program, and at the same time, it also carries a huge mission. Chang'e-5 is the sixth mission of the lunar exploration program, and it is also the most difficult and tedious of them.

She will carry out our country's first unmanned lunar surface sampling and return probe to Earth. <>

Unmanned "sample return" is Chang'e-5's top priority. The so-called unmanned "sample return" is to successfully obtain the soil on the surface of the moon and return it to the earth under fully automatic conditions. After obtaining these soils, surface researchers can further study the lunar environment in more depth, analyze the surface structure, material composition, and physical characteristics of the moon, so that human beings can have a deeper understanding of the moon.

The lunar sampling was divided into surface sampling and two-meter subsurface sampling. This time, Chang'e-5 successfully completed its mission, successfully landed in Siziwangqi, Inner Mongolia, and brought back a total of 2 kilograms of lunar soil samples. It is reported that some of these soil samples will be stored in Beijing and some in Hunan.

The reason why it is stored in Hunan is to mourn our great leader, who is his hometown, and he also issued a call to "go to the moon for nine days". <>

Congratulations to Chang'e-5 on the successful completion of its mission. At the same time, it is also hoped that China's aerospace industry can make rapid progress and walk in the forefront of the world.

Chang'e-5 returned from a business trip and brought back some soil from the moon to deepen the study of the origin and evolution history of the moon in order to improve the structure, physical properties and material composition of the lunar soil.

Its space journey has provided a lot of effective information for our country, and has also made people more aware of the soil on the moon and the environment of the moon, and has also made great efforts for the aviation industry, promoting the development of China's comprehensive strength.

It has brought us a lot of information, and it has also brought back the soil on the surface of the moon, and this soil has a high research value, but it also proves that this soil cannot be cultivated, and it also represents the continuous improvement of our country's technology, and at the same time, it can also improve the international status of our country.

Chang'e-5 brought back two kilograms of soil from space, and then scientists studied it and found that there were no nutrients in it, it could not grow vegetables, and it was not suitable for survival.

This operation can provide China with information on the surface structure and material characteristics of the moon. It can speed up China's research on space, and also make a big step forward in China's scientific and technological level.

Chang'e-5 successfully landed on the moon, what is this mission, and when is the return time?

The mission of Chang'e-5 to the moon is mainly to collect lunar soil and study the history of lunar evolution, as well as test automatic sampling and packaging, lunar surface take-off and lunar orbit docking, etc.

Chang'e-5 successfully landed, and the process of Chang'e-5's landing on the moon was that the rocket took them to the earth, and then transferred from the earth to the moon, collected on the moon, and then returned to the earth, and the task was to go to the moon to collect soil.

The Chang'e-5 ascender 3000N engine worked for about 6 minutes and successfully sent the sample-carrying ascender into the predetermined orbit around the moon. This is the first time that an extraterrestrial object has taken off in China. It is another achievement in the history of aerospace and is of great significance.

Chang'e-5 will collect about 2 kilograms of lunar soil from the moon, seal it and return the lunar samples to Earth through lunar takeoff, lunar orbit rendezvous and docking, moon-to-earth transfer and re-entry**.

The Long March 5 Yao-5 carrier rocket was used to send the probe into a predetermined orbit, and after completing several orbit corrections, it landed smoothly, and the task was to bring the soil on the surface of the moon back to the earth for study, and the second was to realize the automatic sample return of extraterrestrial objects.

Chang'e-5 encountered technical problems such as abnormal weather during the lunar landing, and finally successfully landed and returned to Earth with unremitting efforts. All this was solved because of the day and night guard of the staff and astronauts. Chang'e-2 was successfully launched as a pilot mission for the second phase of the project.

After high-resolution imaging of the Hongwan area where Chang'e-3 will land, the expanded mission began, completing technical tests into orbit around point L2 in Lagrange, Japan, and then flying by the asteroid Tutatis and sending it back**. Chang'e-2 has become China's farthest probe from Earth and has set a precedent for China's multi-target deep space exploration. The Chang'e-3 probe consists of a lander and a patrol aircraft.

All landed in the Hongwan area on the far side of the moon. After landing, the patrol and lander separated and each completed the scheduled mission of lunar surface exploration. The Chang'e-5 flight test vehicle is mainly used to verify the semi-ballistic jump reentry and return technology.

After the earth-moon rotation, near-moon rotation, and month-by-month rotation, the return capsule leaves the service cabin and re-enters the return flight. Finally, it successfully landed in the predetermined area of the Siziwang Banner in Inner Mongolia.

The balance in the lunar sky, the bulkiness of astronauts, the basic conditions for landing on the moon, accidents on the way, the reserve of oxygen, etc., it is necessary to take precautions in advance, and at the same time, it is necessary to solve these problems in advance, and to envision all kinds of dangers before landing on the moon.

The maximum amount of lunar soil collected by Chang'e-5 is much more than 2 kg, but 4 kg. The lunar orbit will automatically rendezvous and dock, and having a powerful spacecraft system is only the first step, how to collect and grab the lunar soil is the second difficulty. To this end, Chang'e-5 is equipped with two sets of lunar soil harvesting systems for drilling and surface sampling.

The corresponding actuators are a core drilling rig and a sampling manipulator. Throughout the history of human spaceflight, Chang'e-5 is still the only one in the world to use two sets of sampling mechanisms on an extraterrestrial planet at the same time. If you want to control these two sampling systems, you need to have sufficient power from the upper components

The difficulty encountered in the process of landing on the moon is that the orbit is different from the established orbit, and it is a slope when landing, so it is particularly difficult, and it has been successfully solved through the precise operation of scientists.

First of all, there is no way to determine the landing place, and Chang'e 5 deviated from its original orbit during the journey, but the mass of this spacecraft is relatively high, so there were no accidents after that.

On September 25, 2008, Zhai Zhigang, Liu Boming and Jing Haipeng entered space for the third time and completed a spacewalk in space (the spacewalk was completed by Zhai Zhigang).

October 15, 2003 Yang Liwei.

For the first time into space.

On October 12, 2005, Nie Haisheng was born.

and Fei Junlong went into space for the second time.

Space journey, my country's space journey again and again, in the face of the development of science and technology, you want to say something.

Dear, I'm glad to be able to answer for you, the development of China's aerospace industry, from "Shen I" to "Shen V", Uncle Yang Liwei has already believed in the "Shen V" to heaven. Successively, the manned spacecraft of "Shen V" Qiao Ye Zao, and the "Shen VI" successfully lifted off, it went to explore the universe, and the two astronauts: Nie Haisheng and Fei Junlong returned victoriously!

What an exciting time, this is the pride and pride of the Chinese people. Thousands of Chinese sons and daughters are extremely excited, and another new initiative has been born! Space will also give us a new living environment.

It will bring rapid development to our Xiaoque's science and technology.

The Chang'e-5 probe was successfully launchedThis historic moment is of epoch-making significanceBecause this is our further exploration of the moon, you let us get more in-depth information, and a detailed understanding of the moon, then for the moon after the soil is taken, we can analyze the lunar soil to know, what is on the moon, whether it will generate water, or other objects, what is on the moon can survive or whether there is any living thing, then for these things is very necessary. In fact, for such an exploratory thing, our country has also done a lot. For various countries, it is also more serious to explore the changes in the entire outer space.

This historic moment indicates that China has made great achievements in the aerospace industry and is no longer a backward country.

The successful launch of Chang'e-5 represents a further step in China's space industry, a new stage in human exploration of space, and a growing strength.

The successful launch of the Chang'e-5 probe, wow, this historic moment is quite significant, this is a new initiative after China's Chang'e-1 4, and this initiative will bring new discoveries to China's research on the moon, which is of great significance.

The successful launch of the Chang'e-5 probe is of great significance, which marks a new milestone in China's aerospace technology and the rise of China's science and technology.

The "Chang'e-5" lunar exploration satellite is expected to be launched at the end of this year, which makes me feel very deeply, and I think that China's lunar exploration undertaking has reached a new height. And this time will also draw a strong stroke for the development of China's aerospace industry.

China began its lunar exploration program in 2004 and became the fourth country in the world to launch a lunar exploration satellite. And the aerospace strength of our country is also close to that of Russia and the United States. With the development of China's aerospace industry over the past ten years and the continuous upgrading of satellites, I believe that our country will gradually unravel the mystery of the moon and realize the dreams and aspirations of generations of China's aerospace people.

And China will also achieve the grand goal of catching up with Russia and the United States in its comprehensive aerospace strength.

Looking back on the 5,000-year history of China, China's ancient working people have always had a beautiful yearning for the moon, and this beautiful yearning has continued to this day, and the launch of the "Chang'e-5" lunar exploration satellite will also carry this beautiful yearning of the Chinese people. I have been a student for almost 15 years, and during this time, I can see that there is a certain figure of the moon in both textbooks and extracurricular books, which is enough to see the place of the moon in our hearts. As a student, I was also a dead house, and I found the shadow of the moon in many foreign anime and manga works.

For example, the heroine of Ultraman Ace in the special film filmed by Tsuburaya Co., Ltd. in Japan, Nan Yuzi is a moon man, she conceals her identity and transforms into Ultraman Ace, the guardian god of the earth, together with the male protagonist, an ordinary earth baker, Hokuto Seiji, to resist foreign aggression. Such a character setting expresses the beautiful yearning of the screenwriter and director of this special film for the moon and the beautiful fantasy that the moon people can live in harmony with the earthlings. There are many more such examples, and I will not repeat them here.

In conclusion, I would like to say that I am full of confidence in China's launch of the "Chang'e-5" satellite at the end of the year, and I am also proud to be a Chinese. On the occasion of the National Day and the Mid-Autumn Festival, I sincerely wish that China's aerospace industry will blossom and blossom.

CCTV***: The 2020 China Space Conference is currently being held in Fuzhou. Aerospace experts from many fields gathered together to jointly understand the direction and plan of China's aerospace development in the future.

Yu Dengyun, deputy chief designer of the lunar exploration project, introduced the "Chang'e-5" mission to be carried out at the end of this year.

Chang'e-5 will carry out a lunar coverage and return mission, which is also the final work of China's third lunar exploration phase. Compared with previous missions, Chang'e-5 has the heaviest task and faces more technical problems. Once the sampling is complete, the probe will bring the sample back to Earth.

In this process, the first challenge is the lunar take-off.

Yu Dengyun said that Chang'e-5 is expected to achieve four "firsts" in China's aerospace history: the first time to automatically sample on the surface of the moon, the first time to take off from the lunar surface, the first time to carry out unmanned rendezvous and docking in the lunar orbit 380,000 kilometers away, and the first time to return to the earth with lunar soil at a speed close to the second universe.

Looking ahead, Chang'e-6 plans to return samples from the moon's south pole. Chang'e-7 plans to carry out a detailed survey of the resources of the moon's south pole and carry out a comprehensive exploration mission of the moon's topography, landform, material composition and space environment. In addition to continuing scientific exploration experiments, Chang'e-8 will also carry out lunar surface tests and technical utilization of some key technologies.

Yu Dengyun said that China is carrying out the development of a space station and a manned landing on the moon to deepen the demonstration. In accordance with the "three-step" plan of the manned spaceflight project, the manned spacecraft and space laboratory have been completed. With the successful first flight of the Long March 5B rocket, the construction of China's space station project has entered a substantial stage.

China also plans to build an unmanned lunar scientific research station and carry out manned lunar landing.
