Touring the satellites of Saturn

A set of possible options is being considered for the next mission to Saturn after the Voyager flybys. Many of these options will include a Saturn orbiter which will provide detailed investigations of the atmosphere, magnetosphere, ring system and satellites of Saturn. The feasibility of designing Saturnian satellite tours which satisfy the science objectives and are consistent with mission requirements and constraints is explored. An orbiter mission is possible through using gravity assist trajectories to target the spacecraft from one satellite encounter to the next. A challenge in designing trajectories to encounter all the satellites is that Titan is the only massive satellite available for gravity assist. Two reference tours are presented illustrating different strategies to achieve the science objectives.
