许多科学飞行任务需要畅通无阻的空间视野和稳定的热环境，但缺乏达到满足这些需求的轨道的技术或方案资源。这篇文章介绍了一个与月球2：1共振的高地球轨道，它提供了这些条件，通过月球重力辅助达到。分析制导和数值研究对这一非常规轨道的行为有了深刻的了解，使其有可能选择稳健的任务设计。解决方案可用于广泛的任务，从较小的探索者级任务，如凌日系外行星调查卫星，到寻求传统拉格朗日点、漂移和地球同步轨道的较低增量V替代的较大任务。
Many science missions require an unobstructed view of space and a stable thermal environment but lack the technical or programmatic resources to reach orbits that satisfy these needs. This paper presents a high Earth orbit in 2:1 resonance with the Moon that provides these conditions, reached via lunar gravity assist. Analytical guidance and numerical investigation yielded deep insight into this unconventional orbit's behavior, making it possible to select a robust mission design. Solutions are available for a broad range of missions, from smaller Explorer-class missions such as the Transiting Exoplanet Survey Satellite to larger missions that seek lower-Delta V alternatives to traditional Lagrange-point, drift-away, and geosynchronous orbits.
