When will China land on the moon?

"Chang'e's" moon landing around 2022

China's first moon landing plan is divided into three steps

According to the relevant person in charge of China's lunar exploration program, If the goal of sending astronauts into space is successfully achieved in the next few years, China is expected to complete its first lunar exploration before 2010.

According to the latest publication of "Lookout" weekly report, China's moon landing plan. It is carried out in three steps: the first step is to launch the space laboratory and the lunar orbiter to search for precious elements; the second step is to realize the space robot landing on the moon; the third step is to carry out the manned moon landing. Although the specific time of the moon landing is not yet available. Absolutely certain, but aerospace scientists are certain that China will take less time to land humans on the moon than the United States.

Moon exploration is an important symbol of the high development of a country's space technology, and it is also the most important goal for countries to explore space business opportunities. One.

The Chinese government issued a white paper on China's space exploration in November 2000, initially establishing the goals of lunar exploration and clearly stating that the short-term development goals include "carrying out preliminary research on deep space exploration focusing on lunar exploration." ". At the same time, it is proposed that the goal of choosing lunar exploration must have outstanding characteristics, not only to fill China's gaps in the field of lunar exploration, but also to add new scientific basis for mankind to establish a lunar base, and try to avoid repeating the work that other countries have done.

China has established the first specialized research institution for space robots for the moon landing plan, namely the National High-tech Space Robot Engineering Research Center. Space robot experts at the center said: Space robots will be used when Chinese people land on the moon. It will undertake major exploration missions in front of the moon and play an important role in satellite maintenance, space science experiments and other activities. It is hoped that when an international lunar base is established in the future, China can also contribute to the robots used for lunar surface exploration according to existing design models. It is light, small and dexterous, can move freely, climb hills and avoid obstacles, and can adapt to the environment of large temperature differences and radiation on the moon.

Some scientists predict that one of China's greatest achievements in the 21st century will be the construction and utilization of space. Solar energy "Moon City" - excess energy will be transmitted to collection points on Earth.

Once China successfully lands a man on the moon, it will become a founding member of the world's moon club.

China News Service, November 29. According to the Xinhuanet Shanghai Channel, Ouyang Ziyuan, chief scientist of China's lunar exploration project and academician of the Chinese Academy of Sciences, said here on the 28th that China's Chang'e Project lunar exploration plan is progressing smoothly, and the launch vehicle The five major systems, detector, CNC, launch site and ground application have all completed the preliminary prototype stage, and all technical indicators have been determined. They have now entered the normalization stage. It is expected that the launch of the Chang'e-1 satellite around the moon in 2007 will not be a problem.

Academician Ouyang Ziyuan came to Shanghai at the invitation of the first Yangtze River Delta Youth Innovation Forum to give a keynote report on the characteristics and innovation of space exploration and China's lunar exploration.

According to Academician Ouyang, China. The lunar exploration plan has gone through long-term preparation and ten years of demonstration. In fact, before the Chang'e project was officially launched in January 2004, many units had invested a lot of money in various preliminary studies. For such a huge system project, scientists first divided it into five major systems for design respectively. After the design plan was discussed and approved, a principle prototype was developed. The prototype was then subjected to various complex experiments to produce a preliminary prototype. After the technical indicators are determined, they need to be converted into positive samples, and then various tests such as single test, joint test, comprehensive test, etc. are carried out on the original samples to ensure that every link is foolproof.

China's Chang'e Project lunar exploration plan is mainly divided into three stages: orbiting, landing and return: 2004-2007 is the orbiting stage, the main goal is to launch the Chang'e-1 satellite and conduct one-year exploration around the moon; The landing stage from 2007 to 2012 is the main goal of achieving soft landing on the lunar surface and lunar patrol detection; the return stage from 2012 to 2017 is the main goal of soft landing on the lunar surface and sample return. Only after completing these three stages will China consider manned landing on the moon.

Currently, China has selected the Xichang Satellite Launch Base to launch the Chang'e-1 satellite, and the launch rocket has selected the Long March-3A. The Chang'e-1 satellite was developed by the China Academy of Space Technology. At present, the entire satellite test of the initial prototype satellite has been completed, and the development of the full-scale satellite has begun. The Long March 3A rocket responsible for the satellite launch mission has also been put into production. In order to ensure the completion of the moon For the detection engineering mission, scientific researchers carried out 41 designs to improve the reliability of the Changsanjia rocket. (

China announced its first lunar exploration plan, the Chang'e Project, on February 13, 2004. The plan is divided into three development stages: "orbiting, landing and returning". The first phase of "Chang'e 1" will orbit the moon. The project, with a total investment of 1.4 billion yuan (a common metaphor is: "The cost of the first lunar exploration project is equivalent to the cost of building a two- to three-kilometer subway.") will launch a moon-orbiting satellite before 2007. . In the next 10 years, China will successively carry out soft landings of lunar rovers and robotic lunar soil sampling.

[edit] The four major tasks of the first phase of the "Chang'e-1" lunar orbiting project are

1. Obtain three-dimensional images of the lunar surface and finely divide the basic structure and landforms of the lunar surface Unit, conducts research on the shape, size, distribution, density, etc. of impact craters on the lunar surface, provides basic data for the classification of the surface age of terrestrial planets and research on early evolutionary history, and provides information for the site selection of soft landing areas on the lunar surface and the optimization of the location of lunar bases. Basic information, etc.

2. Analyze the content and distribution characteristics of useful elements and material types on the lunar surface, mainly to survey the content and distribution of 14 elements such as titanium and iron that are valuable for development and utilization on the lunar surface, and map the entire moon for each element. Distribution maps, thematic maps of lunar rocks, minerals and geology, etc., discover the enrichment areas of various elements on the lunar surface, and evaluate the development and utilization prospects of lunar mineral resources.

3. Detecting the thickness of the lunar soil, that is, using microwave radiation technology to obtain the thickness data of the lunar soil, thereby obtaining the age and distribution of the lunar surface, and on this basis, estimating the nuclear fusion power generation fuel helium -3 content, resource distribution and resource amount, etc.

4. Detect the space environment from the earth to the moon. The average distance between the moon and the earth is 380,000 kilometers, and it is located in the far magnetotail region of the earth's magnetic field space. In this area, satellites can detect high-energy particles of solar cosmic rays and solar wind plasma, and study the interaction between the solar wind and the moon, as well as the magnetotail of the earth's magnetic field and the moon.

Going further in space is becoming a new dream for Chinese astronauts. With the rise of international deep space exploration craze, China's lunar exploration program has also begun to be carried out in full swing. Recently, reporters conducted an exclusive interview with Ouyang Ziyuan, the chief scientist of China's lunar exploration project.
