2022年空间科学与深空探测热点回眸

Review of 2022 global space science advances

2022年世界空间科学和探索热点频现。按空间天文、日球层物理、行星科学、空间地球科学和微重力物理与空间生命科学五大领域,梳理了全球空间科学重要进展,韦布空间望远镜及其首批成果成为年度最大亮点;盘点了各国空间科学任务及其代表性成果,中国空间科学先导专项科学卫星系列以及探月工程“嫦娥五号”样品的研究突破令人瞩目。载人航天是空间科学与应用的重要平台,中国空间站建成引起世界关注。点评了各国的空间科学中长期规划和国家空间战略相关情况,展望了2023年即将发射升空的空间科学新任务。

Hot spots in global space science and exploration emerged frequently in 2022. This paper summarizes significant accomplishments in the five disciplines of space science, namely astrophysics, heliophysics, planetary science, earth science, and biological and physical sciences in space. James Webb Space Telescope and its first batch of groundbreaking images became the highlight of the year. The representative achievements of space science missions of various countries are listed, in which the breakthroughs by missions under CAS’s Strategic Priority Program on Space Science and the research of Chang’e-5 sample are particularly impressive. Manned spaceflight has provided an important platform for space science and exploration. The construction of China’s space station(CSS) completed at late 2022, which has attracted worldwide attention, and CSS is preparing to host 1,000 scientific experiments in the coming 10 years. The space science long-term planning and national space strategies of space powers are presented, and the space missions in 2023 are also prospected in the end of the review.
