The flight dynamics design for the Arcus Probe mission considers mission, science, and operational constraints pertaining to the launch, trajectory, science orbit, and decommissioning phases of the mission. Lunar resonance orbits offer benefits to mission operations, specifically with respect to science observations and data downlink opportunities. Post-separation implementation uses Earth phasing loops to raise and position the apogee for lunar swingby. Leveraging lunar gravity is a feature throughout the trajectory to the final science orbit, which similarly uses resonance with the Moon for maintenance. A detailed implementation approach constructs a viable solution set for the Arcus Probe mission. Trade studies assess the benefits of cis-lunar mission design for three examples of lunar resonance patterns.

Arcus观测目标的月球共振轨道设计


Arcus 探测器任务的飞行动力学设计考虑了与任务的发射、轨道、科学轨道和退役阶段相关的任务、科学和操作限制。月球共振轨道为任务操作带来好处，特别是在科学观测和数据下行机会方面​​。分离后实施使用地球定相环来升高和定位月球绕转的远地点。利用月球引力是通往最终科学轨道的整个轨迹的一个特征，它同样利用与月球的共振来进行维护。详细的实施方法为 Arcus 探测任务构建了一套可行的解决方案。权衡研究评估了顺月任务设计的三个月球共振模式示例的好处。
