On January 28, the Information Office of the State Council released the white paper "China's Aerospace in 2021". Liu Jizhong, director of the Lunar Exploration and Aerospace Engineering Center of the China National Space Administration, said at a press conference on the same day that the mainland will focus on the universe, the solar system and its planetary evolution, as well as the impact of solar activity on the earth, through the follow-up lunar exploration project Phase IV, planetary exploration project, space station operation and follow-up space science special satellite missions, such as space astronomy, space physics exploration, etc. "Through the implementation of these missions and cooperation with counterparts in various countries, we will definitely be interested in the development of space science and the development of mankind. It plays an important role in promoting. ”
Liu Jizhong said that in the past five years, the lunar exploration project, "Tianwen-1", and space science engineering tasks, such as "Wukong" and "Mozi", have played a very big role in promoting and driving space science.
First, in terms of historical evolution, through the study of the shallow structure of the moon, the evolutionary history of the moon has been made, especially in terms of geology. Through the analysis and study of the lunar samples of Chang'e-5 in the early stage, the timeline of lunar geological activity was deduced from the original 3 billion years to 2 billion years, that is to say, the moon was about 1 billion years younger. These understandings of the Moon play a very crucial role.
Second, from the perspective of material energy, a new type of deep lunar material has been discovered through preliminary research, and the fine structure of the cosmic ray energy spectrum that has been relatively accurate so far has also been discovered.
Third, from the perspective of the space environment, through several years of scientific research, the radiation dose of lunar particles has a new understanding and obtains new values. In addition, the lunar micromagnetic layer was discovered, establishing a new model and mechanism for the interaction between the solar wind and the moon. "At the same time, through observations of the Earth from space, we have also gained a new understanding of the entire active evolution of the Earth's plasma layer."
Liu Jizhong said that while achieving these results, the mainland has established a number of scientific research facilities around scientific research. This has laid a very good foundation for future scientific research and scientific cooperation with international peers. Through the implementation of these projects, scientific research has been deepened. "According to statistics, more than 100 universities have established disciplines related to the field of space science, and there are also many international students. This is very important for the talent pool for future space science research. Liu Jizhong said that the progress of science is very important for the development of human civilization, and China's follow-up deep space exploration activities will not stop.
