Outline of Final Research Achievements |
The purpose of this research is to establish a low energy transfer from the Earth to the Moon by using the coupled 3-body system with perturbations for modeling the planar restricted 4-body system. We have detected the tubes which correspond to the stable and unstable manifolds of the perturbed systems by numerically extracting the LCS from the FTLE field. Then, we demonstrate how the LCS separates the orbits. I particular, using the characteristics of the tube structures, we obtain the family of trajectories that depart from the LEO and the family of those that arrive into the LLO. Finally we have shown how a low energy Earth-Moon transfer can be constructed by choosing an appropriate orbit from each family such that the required Delta V can be minimized under the given conditions.
