Abstract: Deep space exploration plays a significant role in answering some basic scientific questions puzzled human like universe origin and life evolution. However, many key technologies without un-mastered including advanced propulsion technology limit future exploration activities. In this paper, a new magnetic propulsion method without propellant consumption applying to the deep space exploration is described. It creates the thrust by the interaction between the plasma fluid of solar wind and the magnetic field created by the spacecraft itself with carrying a loop of superconducting cable electrifying. Firstly, the domestic and foreign development present situation of magnetic propulsion are summarized. Secondly, the basic principles of magnetic propulsion are explained. Finally, the technology characteristics and potential applications in deep space exploration are analyzed.
