Trajectory design based on lobe dynamics with resilience to missed thrust events
Quando
Abstract: Trajectory design in cislunar space is challenging due to chaotic and nonlinear dynamics. In this talk, we focus on lobe dynamics to reveal phase space transport. Lobe dynamics focuses on the "lobe", the region determined by stable and unstable manifolds of a resonant orbit. Based on lobe dynamics, we construct fuel-efficient transfers between the LEO and LLO. In addition, this framework is extended to enable trajectory design resilient to missed thrust events by jointly designing nominal and recovery trajectories.
