With the increasingly issues of energy crisis and environmental pollution，technologies with energy conservation and consumption reduction functions have become an urgent demand in the aerospace field.Surface micro-textures have been widely applied in the aerospace field，owing to their excellent functional properties such as friction reduction and drag reduction.In this paper，the functional mechanisms of surface micro-textures and their typical applications in the aerospace field are thoroughly explicated from the aspects such as friction reduction，drag reduction，thermal management，anti-icing，and self-cleaning.The challenges and solutions of surface micro-texture applications in the aerospace field are summarized，and the future development directions are proposed.
