Low-Energy Cislunar Transfers via Lobe Dynamics

This paper presents a systematic method for designing low-energy transfers in cislunar space using sequences of lobe dynamics. Lobe dynamics, which exploit chaotic transport around celestial bodies, are fundamental for designing fuel-efficient trajectories. The authors develop a graph-based framework to explore possible transfer paths between departure and arrival orbits, reducing the complexity of the optimization problem. Low-energy transfer trajectories are constructed by connecting chaotic orbits within lobes. The resulting optimal trajectory in the Earth-Moon CR3BP is then converted into an optimal transfer in the bicircular restricted four-body problem via multiple shooting. The method is validated against existing optimal solutions, demonstrating its effectiveness. This approach could enable more frequent and affordable cislunar missions by reducing fuel consumption and mission costs. The graph-based framework simplifies the design of complex transfer trajectories.
