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