CNR:

We know from the introduction just now that China has made many important achievements in the space sector in the past five years. Could you please provide a brief review? Besides, what are the key development directions for the future? Thank you.

Liu Jizhong:

Let me take your questions. Over the past five years, China has boosted the development of space science through its lunar exploration program, the Tianwen-1 Mars probe and space science programs like the Wukong and Mozi satellites. It covers the following aspects: First, from the perspective of evolutionary history, we have gained a new understanding of the evolution of the moon, especially in geological terms, by studying the moon's subsurface structure. Based on the analysis and research of lunar samples collected during the Chang'e-5 mission, we deduced that the geological activities of the moon date back to 2 billion years ago, which was previously thought to be 3 billion years ago. It means the moon is approximately 1 billion years younger. These understandings of the moon, including those of the evolution of the lunar landscape, are of crucial significance. Second, from the perspective of matter and energy, we discovered new types of lunar matter of deep-seated origin through preliminary studies and the relatively precise fine structure in the cosmic-ray energy spectrum. Third, from the perspective of the space environment, through several years of scientific research, we have a new understanding of the radiation of lunar particles and obtained new numerical values. We discovered the lunar micromagnetosphere, and established a new model and rationale for the interaction between solar wind and the moon. At the same time, we have gained a new understanding of the evolution of the Earth's plasma layer activities through the observation of the Earth from space.

Indeed, we have scored many scientific achievements as well. Meanwhile, we have established a batch of facilities for scientific research, which lays a solid foundation for future scientific research and cooperation with international peers. The implementation of these projects has further promoted scientific research. According to statistics, more than 100 colleges have set up disciplines related to space science and enrolled plenty of international students. These serve as a sound foundation for building a talent base for future space science research, which is crucial.

Scientific progress is of paramount importance to the development of human civilization. Hence, China will not cease its deep space exploration. We will focus on issues including the universe, the solar system and development of its planets, and the influence of solar activity on earth. We will roll out tasks like the fourth phase of the lunar exploration program, the planetary exploration program, space station operations, and follow-up special satellite missions such as space astronomy and space physics exploration. By carrying out these tasks and cooperating with other countries, we will bolster the development of both space science and humanity. Thank you.
