Abstract：Microgravity science is an important branch of space science. To some extent, its frontier projects reflect the ability of human beings to understand nature and the research levels of various countries in this field. Under the extreme physical condition of microgravity, it is pregnant with the prospects of the discovery of new phenomena and laws in physical and chemical processes and material preparation, as well as the realization of the test and the verification of basic physical laws with higher precision. In this paper, the most important research progress of microgravity science in recent years is reviewed.
