LOW ENERGY FREQUENT EUROPA - CALLISTO TRAJECTORIES

摘要

In the future, human is likely to turn their attention to establish an outpost in Jovian System. With the outpost, an ultimate exploration and exploitation of the Jovian system as replica of the solar system can be secured with potential to extend the exploration to further destination of the solar system or beyond. Outpost base location at low Callisto orbit is taken as baseline. Provided the outpost were established, frequent transportation to/from Europa as resource of energy is a must. Minimum energy (C3) required for direct flight from Callisto to Europa are 5.1 km~2/s~2(departure) and 8.7 km~2/s~2(arrival). Gravity assist(s) from Ganymede reduce the figure significantly with reasonable flight time increase. Also the path opportunities are frequently repeated; make them attractive to be considered as the transportation basic means. Launch opportunities for some trajectory paths in 1 year time is presented.
