In the trajectory design to Jupiter, various interplanetary flight modes have been investigated. In this paper, the general characteristics of four interplanetary flight modes, that is, direct Earth-Jupiter trajectories, Mars gravity assist trajectories, deep space &htri;V-Earth gravity assist trajectories, and Venus-Earth gravity assist trajectories, are considered. Each mode is evaluated in terms of required &htri;V and flight time, and the periodicity of the launch opportunity for each mode is classified. The solutions are obtained by a new trajectory generation method which seeks the optimal trajectories including the intermediate impulses and the powered swingbys. Also, the procedure which gives the initial values to reach the optimal trajectories is described.
