The international cooperation in the astronautics research field reflects the vision of humanity sharing space data, exchanging space knowledge, and establishing a community with a shared destiny in outer space. Rather than narrowly tracking research trends solely within China or foreign astronautics domains, it is more beneficial to mine and evaluate Sino-foreign collaboration from bibliographic data. In this paper, we collected bibliographic data from approximately 20,000 astronautics research papers involving Chinese scholars from the world's largest abstract and citation academic database, Scopus. We conducted statistical analyses on the countries of collaborating institutions, identifying several predominant and emerging nations. Furthermore, we analyzed China's collaboration volume, collaboration rate, and leadership in astronautics research with different countries over time, unearthing the impact of international collaboration on research keywords. Concerning the overall landscape of Sino-foreign research collaboration, we also examined the unique characteristics of the aerospace field. The conclusion of this paper underscores that enhancing academic cooperation in the aerospace domain remains a model of collaborative advantage for future aerospace development, particularly emphasizing collaboration with emerging aerospace nations.
