Towards 2030: The Development and Prospect of Chinese Space Astronomy

Fang Taotao

Abstract: Astronomy is a scientific discipline for humans to understand the space and explore the universe, and space astronomy focuses on using space observation equipment to conduct scientific research on the universe. This paper first introduces the development of international astronomy, as well as the main direction and key problems of modern astronomical research. Secondly, it focuses on the development of space astronomy in China, and introduces the key directions of several spatial astronomical studies, using the missing baryon problem as an example. Finally, the paper discusses how Chinese astronomical institutions conduct and support spatial astronomical research, and the prospect of its future development.

Keywords: Space Astronomy, Universe, the Baryon Problem
