The endgame scenario that was explored in this analysis consisted of the part of the trajectory starting at the last Ganymede flyby and ending at the final Europa approach. The basic design components included computing the phasing for the final Ganymede encounter, computing the required intermediate Europa flybys, determining the required maneuvers to transition between the intermediate resonances, and interfacing with a computed portal prior to the final approach. The JPL optimization software, COSMIC, was used in the ephemeris model to optimize solutions computed in the circular restricted three-body problem and compute bounds on the attainable set of solutions by sweeping various design parameters.

在此分析中探索的最终游戏场景包括轨迹的一部分，从最后一次木卫三飞越开始，到最终的欧罗巴进场结束。基本设计组件包括计算最终木卫三遭遇的阶段，计算所需的中间欧罗巴飞越，确定在中间共振之间过渡所需的机动以及在最终进场之前与计算出的传送门对接。星历模型中使用了JPL优化软件COSMIC，以优化在圆形受限三体问题中计算出的解，并通过扫描各种设计参数来计算可达到的解集的边界。
