摘要：
Recent studies suggest significant benefits from using 1(st) and 2(nd) generation Radioisotope Power Systems (RPS) as a power source for electric propulsion (EP) missions to the outer planets. This study focuses on trajectories to the Trojan asteroids. A high level analysis is performed with chemical trajectories to determine potential candidates for REP trajectory optimization. Extensive analysis of direct trajectories using REP is performed on these candidates. Solar Electric Propulsion (SEP) trajectories are also considered for comparison against REP trajectories. A spacecraft mass is derived for the different types of missions, providing insight to how the REP (both 1(st) and 2(nd) generation) missions compare with chemical and SEP missions.
