The embodiment of the invention provides a separation device for an aerospace craft, and the separation device comprises a separation shell, the outer surface of the separation shell is provided witha weakening groove, and the weakening groove divides the outer surface of the separation shell into two parts; an explosion expansion assembly; a protective cover which is provided with a containing groove, the explosion expansion assembly is arranged in the containing groove, the protective cover is fixed to the inner surface of the separation shell, a groove opening of the containing groove faces the inner surface of the separation shell, and the explosion expansion assembly and the weakening groove are arranged back to back; wherein the weakening groove is used for weakening the strength and rigidity of the separation shell at the weakening groove, and when the explosion expansion assembly explodes to generate expansion deformation, the acting force of the expansion deformation of the explosion expansion assembly divides the separation shell into two parts along the weakening groove. According to the separation device of the invention, the technical problem that a traditional separation device cannot meet the development requirements of aerospace crafts is solved.
