這七個計劃涵蓋了空間天文的各個方向，總共包括了19個空間衛星或空間站探測器項目。

縱觀世界各國空間天文的發展，無一不經過長期堅持不懈的努力。而空間研究本身就是一個高風險的領域，歐美及日本都有不少衛星失敗的教訓。我們國家的空間研究還處在剛剛起步的階段，但我們相信，我國研究人員能充分認識到挑戰和機遇，遵循科學發展規律，在空間研究領域為人類做出更多貢獻。

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
