a) MMX: I adjusted the ballistic capture model and computed quasi-periodic orbits near Phobos. I investigated the orbit design and demonstrated that the baseline QSOs can be maintained with as low as 6.3 m/s a month. Impulsive transfers indicates budget ~100 m/s and ToF between 7 hr and 2 days.b) DESTINY+: I optimized the GTO-to-Moon spiral ascent and the interplanetary cruise to Phaethon under strict operational constraints. High-fidelitysolutions give robustness against programmatic and operational delays.a) EQUULEUS: I provided the end-to-end trajectory product, accounting for realistic high-fidelity models and operational constraints. I shed light to the solution structure for optimal lunar transfers, creating a database oftransfers compatible with the launch parameters.

a) MMX：我调整了弹道捕获模型并计算了火卫一附近的准周期轨道。我研究了轨道设计，并证明基线qso可以维持低至6.3 m/s /月。脉冲传输的预算为100m /s， ToF在7小时到2天之间。b) DESTINY+：在严格的操作约束下，优化了gto到月球的螺旋上升和到Phaethon的行星际巡航。高保真度解决方案对编程和操作延迟具有鲁棒性。a) EQUULEUS：我提供了端到端的轨迹产品，考虑到现实的高保真模型和操作约束。我阐明了最佳月球传输的解决方案结构，创建了一个与发射参数兼容的传输数据库。
