Abstract: In using the resonance theory to study the motion of a space vehicle, the corresponding non-Keplerian orbits are named the resonance orbits. In this paper the general dynamical model for resonance orbits is established through a judicious choice of orbit parameters，the time scale，and the thrust representation. An analysis of the influence of the resonance frequency is made based on simulations. The possibility and the effect of the resonance orbits to be used in the deep space exploration through analyzing an Earth-Mars mission are explored. It is shown that, changing the circle frequency will influence the peak thrust; it is possible to use the resonance orbits in the deep space exploration, and its energy consumption is less than using a Lambert orbit.
