Capacity of Sun-driven lunar swingby sequences and their application in asteroid retrieval

For deep-space mission design, the gravity of Sun and Moon can be first considered utilized. Their provide energy change for launching spacecraft retrieving as well asteroids. Regarding an asteroid retrieval mission, it lead to mitigation hazards easy exploration exploitation asteroid. This paper discusses application Sun-driven lunar swingby sequence missions. Characterizing capacity this technique is not only interesting in terms dynamic insights but also non-trivial trajectory design. The a elucidated with help "Swingby-Jacobi" graph. represented by range Jacobi integral that encloses around 660 asteroids currently cataloged. To facilitate database Sun-perturbed Moon-to-Moon transfers, including multi-revolution cases generated employed. Massive options launch capture then explored optimized. Finally, number flyby, rendezvous, sample-return, enabled proposed are obtained.
