Resonance Hop

Author: Tianjiang Shuo Website: https://cislunarspace.cn

Definition

The core maneuver strategy of SMART-1-like low-energy transfers. Each time the spacecraft crosses the L₁ neck region, its trajectory shifts from one near-resonant state to another, progressively reducing energy until entering the Moon's sphere of influence. Essentially an engineering exploitation of chaotic dynamics in the three-body problem.

Application Value

This concept plays a key role in trajectory transfer design, helping evaluate transfer costs and flight time to provide quantitative basis for mission trade studies. Combined with global search algorithms, multiple solution families and Pareto frontiers can be identified to guide orbital design decisions.
