回顾了2020年10月至2021年10月国际空间站在技术开发与验证、物理科学、生物学与生物技术、教育和文化活动、人体研究及地球与空间科学6个领域的科研与应用情况，分析了各领域的代表性新实验，盘点了这一时期取得的亮点研究成果。分析表明，2021年国际空间站继续开展大规模的科研与应用活动，美国、日本、欧洲和加拿大的航天机构在6大研究领域支持开展了313项实验，其中在国际空间站首次开展的新实验超过40%。同时，国际空间站正处于科研与应用产出高峰期，6大研究领域都持续产出新的亮点科研成果，例如微重力生物采矿表现更好、观测地球蓝色喷流等，吸引了全球科技界的广泛关注。
This paper reviews the latest scientific research and application activities of the International Space Station (ISS), to provide a reference for the scientific planning of China's space station, with the overall situation of scientific research and application activities of the ISS from October 2020 to October 2021 considered in six categories, including the technology development and demonstration, the physical science, the biology and biotechnology, the educational and cultural activities, the human research, and the earth and space science, focusing on the new experiments and achievements to reflect the scientific research and application progress during this period. It is shown that, the large-scale research and application activities are continued on the ISS in 2021, with the U.S., Japanese, European and Canadian space agencies supporting 313 experiments in six categories, including more than 40 percent of new experiments conducted on the ISS for the first time. Meanwhile, the ISS is at the peak of scientific research and application output, and all six categories continue to produce new highlight scientific results, such as the discovery that the biomining is even more effective in the microgravity conditions and the observation of the Earth's blue jets, which has attracted a wide attention from the global science community.
