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.
