Abstract

Incorporating quasi-periodic orbits into the preliminary design process offers a wide range of options to meet mission constraints and address the challenges in a complex trade space. In this investigation, linear stability and quasi-periodic orbit family continuation schemes are examined to meet various types of constraints. Applications in eclipse avoidance and transfer design are examined by leveraging quasi-periodic orbits and their associated hyperbolic manifolds in the lunar region. Solutions are transitioned to an ephemeris model to validate that geometries are maintained in higher-fidelity models. When the natural dynamical structures associated with quasi-periodic orbits are leveraged, novel trajectory solutions can emerge.
