At present, China is actively implementing the Chang e to the moon project, the main task is?

c The Chinese set foot on the moon and conducted research.

Summary. Now Chang'e to the moon is no longer a legend, scientists have realized China's dream of flying to the sky, and they are doing their work rigorously and seriously, because.

Hello dear, welcome to consult me, I am honored to meet you. Now that I see your question, I'll give you the answer to Agitator Sen, please wait a while, Mingmu Oh, I'll be there for you right away.

Your first gear is good, very happy to answer the finch key for you, scientists have realized China's dream of flying, they are rigorous and serious in their work, because they know that a little laxity will bring very serious consequences,

Combined with the materials, what are the characteristics of practice embodied in the implementation of China's "Chang'e Project"?

Answer: Practice is objectively material. According to objective laws, scientific and technological personnel have carried out five successful explorations of the moon by means of satellite systems, carrier rockets, rovers, and other material means.

Practice has agency. The "Chang'e Project" will carry out experimental exploration in stages and purposefully according to four major scientific objectives.

The practice is socio-historical. The project involves a wide range of fields such as satellite systems, launch vehicle systems, and ground application systems; From No. 1 to No. 5, scientific and technological workers used different technologies and conditions to achieve different results from surface detection to smooth return, reflecting the social history of practice.

1. Design and verify the follow-up.

All orbit and maneuver flight control techniques before the descent of power in the land mission directly entered the Earth-Moon transfer orbit, X-band tracking and control was used for the first time, and high-resolution imaging of the Chang'e-3 landing area was carried out.

2. Breakthrough in micro-small intelligent design technology, the first time to realize the monitoring and imaging of the Earth-Moon space flight process. For the first time, the dynamic images of key links such as solar wings, antenna rotation, and main engine ignition were obtained in real time, which provided a visualization method for subsequent important flight events.

3. For the first time, LDPC decoding and coding has been applied in the space segment of aerospace engineering, and the main indicators such as coding gain and efficiency are better than the international (CCSDS) standard, which has improved China's status and voice in the field of international deep space channel decoding and coding.

4. For the first time, the long-life technology of high-pressure gas path of the propulsion system was verified in orbit, laying a dynamic foundation for high-intensity (time span of more than half a year, more than 10 times) orbital maneuvering and subsequent L2 point and asteroid detection tests.

5. For the first time, the integrated technology of detection sensor and payload was broken through, and the imaging sensor was used to complete the satellite-ground large-loop navigation test.

The Chang'e-2 satellite (abbreviation: Chang'e-2, also known as the "2nd satellite") is the sister satellite of the Chang'e-1 satellite, which was launched by a Chang-3C rocket. But the Chang'e-2 satellite will have a higher resolution CCD camera, and other exploration equipment will be improved, and the data about the moon will be more detailed.

Chang'e-2 was launched at 18:59:57 on October 1, 2010 at the Xichang Satellite Launch Center and was a complete success.

As the technical pilot of the second phase of the project, Chang'e-2's main mission is to carry out some key technical tests for Chang'e-3 to achieve a soft landing on the lunar surface, and continue to carry out lunar scientific exploration and research. It was the Long March-3C carrier rocket that sent this "pathfinder" into space. This is the first time that this new rocket with greater thrust has been used for lunar exploration launches, and it is also the 131st flight of the Long March series of rockets.

About 25 minutes after takeoff in sporadic drizzle, the rocket launched the satellite into an Earth-Moon transfer orbit at a perigee altitude of 200 km and an apogee altitude of about 380,000 km. This marks China's successful breakthrough in direct Earth-Moon transfer orbit launch technology.

As early as 1994, China's aerospace science and technology workers conducted a study on the necessity and feasibility of lunar exploration activities, completed a study on the technical scheme of a lunar exploration satellite in 1996, completed a study on key satellite technologies in 1998, and later carried out in-depth demonstration work. After 10 years of deliberation, it was finally decided that China's entire lunar exploration program would be divided into three stages: "orbiting", "landing" and "returning".

The first step is to "orbit", that is, to launch China's first lunar exploration satellite, break through the flight technology of extraterrestrial celestial bodies, realize the flight of lunar exploration satellites around the moon, obtain three-dimensional images of the lunar surface through remote sensing detection, detect the content of useful elements and material types on the lunar surface, detect the characteristics of lunar soil, and explore the Earth-Moon space environment during the flight of the lunar exploration satellite to the moon. The first lunar exploration satellite, Chang'e-1, was launched on 24 October 2007.

The second step is "falling", which is set for the period 2007 to 2010. That is, the launch of the lunar soft lander, breaking through the landing technology of extraterrestrial objects, and carrying the lunar patrol surveyor to carry out the lunar soft landing and automatic patrol survey, to detect the topography and landform, geological structure, chemical and mineral composition of rocks and the environment of the lunar surface in the landing area, to carry out on-site detection and sampling analysis of lunar rocks, and to carry out sun-Earth-lunar space environment monitoring and moon-based astronomical observations. The specific plan is to use rovers and automatic robots that safely land on the lunar surface to detect the rock and mineral composition of the landing area, measure the heat flow and surrounding environment of the landing site, and carry out high-resolution photography and on-site detection or sampling analysis of lunar rocks, so as to provide chemical and physical parameters of the lunar surface for the site selection of the lunar base in the future.

The third step is "return", which is set for 2011 to 2020. That is, the launch of the lunar soft lander, breaking through the technology of returning to the earth from extraterrestrial objects, carrying out automatic sampling of lunar samples and returning them to the earth, analyzing and studying the samples on the earth, and deepening the understanding of the origin and evolution of the earth-moon system. The goal is to survey the lunar surface and return samples.

Orbiting the Moon Lunar Sampling Moon landing.

In 2004, China officially launched a lunar exploration project and named it the "Chang'e Project". The Chang'e project is divided into three phases: "unmanned lunar exploration", "manned lunar landing" and "establishment of a lunar base".

At 18:05 on October 24, 2007, Chang'e-1 was successfully launched, and after successfully completing various missions, it hit the moon in a controlled manner as planned in 2009. At 18:57:59 on October 1, 2010, Chang'e-2 was successfully launched, and all the scheduled tasks have been successfully completed and exceeded. On September 19, 2012, Ouyang Ziyuan, chief scientist of the lunar exploration project, said that the lunar exploration project is carrying out the lunar surface survey mission of the Chang'e-3 satellite and the Yutu lunar rover.

Chang'e-4 is the backup satellite of Chang'e-3. The main scientific objectives of Chang'e-5 include the field investigation and analysis of the landing area, as well as the analysis and study of lunar samples after they are returned to Earth.

In 2004, China officially launched a lunar exploration project and named it the "Chang'e Project". The first phase of the Chang'e project is scheduled to launch China's first lunar exploration satellite, Chang'e-1, to orbit the moon by the end of 2007 and carry out a one-year lunar exploration mission.

As early as 1994, China's aerospace science and technology workers conducted a study on the necessity and feasibility of lunar exploration activities, completed the study of the technical scheme of the lunar exploration satellite in 1996, completed the research on the key technology of the satellite in 1998, and later carried out the work of deepening the demonstration. After 10 years of deliberation, it was finally determined that China's entire lunar exploration project is divided into three stages: "orbiting", "landing" and "returning". The first phase of the lunar orbiting project will launch the lunar exploration satellite "Chang'e-1" in 2006 to explore the lunar surface environment, landform, topography, geological structure and physical field.

The second phase of the project, scheduled for 2007-2010, aims to develop and launch a spacecraft that will land on the moon for exploration in a soft landing. The specific plan is to use rovers and automatic robots that safely land on the lunar surface to detect the rock and mineral composition of the landing area, measure the heat flow and surrounding environment of the landing site, and carry out high-resolution photography and on-site detection or sampling analysis of lunar rocks, so as to provide chemical and physical parameters of the lunar surface for the site selection of the lunar base in the future.

The third phase of the project is scheduled to take place from 2011 to 2020, with the goal of lunar surface survey and sample return. In the early stage, the main thing is to develop and launch a new type of soft landing lunar rover to inspect and survey the landing area. Later, that is, after 2015, we will develop and launch small sampling return capsules, lunar surface rock drills, lunar surface samplers, robot manipulators, etc., collect key samples and return them to the earth, investigate the landing area, and provide data for the next manned lunar exploration and the site selection of lunar outposts.

The completion of this section of the project will bring China's space technology to a new level.

In the project plan submitted by Ouyang Ziyuan, China's Chang'e lunar exploration project is divided into three stages.

The principle of universal connection is as follows:

The main reason why the principle of universal connection can be embodied is that the lunar exploration project is composed of five major systems: satellites, rockets, launch sites, tracking and control, and ground applications, and there is a relationship of mutual influence, mutual constraint, and interaction between these systems and personnel. Philosophically speaking, this relationship of "mutual influence, mutual restraint, and interaction" is the connection, and what is embodied is the principle of universal connection.

Features of Contact:

Connection refers to the relationship between things and between the elements of things that influence, restrict and interact with each other. First and foremost, a connection is a relationship. For example, teacher-student relationships.

Secondly, the connection is the relationship between the mutual influence, mutual constraint and interaction between the elements within the thing. For example, a person's internal organs, bones, muscles, nerves, etc. are mutually influencing, restricting and interacting with each other.

Finally, a connection is a relationship in which things influence each other, condition each other, and interact with each other. As we can see, "Chang'e to the moon".

Because Chang'e's successful flight to the moon is an indispensable part of the lunar exploration project.
