用于低成本空间科学任务的高地球、月球共振轨道

A High Earth, Lunar Resonant Orbit for Lower Cost Space Science Missions

Joseph W. Gangestad, Gregory A. Henning, Randy R. Persinger, George R. Ricker

摘要:

许多科学飞行任务需要无障碍的太空视野和稳定的热环境,但缺乏技术或方案资源来达到满足这些需求的轨道。本文介绍了一个高地球轨道在2:1共振与月球提供这些条件,通过月球重力辅助达到。分析制导和数值研究对这种非常规轨道的行为产生了深刻的洞察力,使选择稳健的任务设计成为可能。解决方案可用于广泛的任务,从较小的探索者级任务(如过境系外行星调查卫星)到寻求较低Delta V替代传统拉格朗日点,漂移和地球同步轨道的大型任务。

英文摘要:

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.
