Survey of Ballistic Transfers to the Lunar Surface

In this study, techniques are developed that allow for an analysis of a range of different types of transfer trajectories from the Earth to the lunar surface. The computation of collision orbits is used as the basis for these techniques, and the resulting methods allow the computation of trajectories that encompass low-energy trajectories as well as more direct transfers. The range of possible trajectory options is summarized, and a broad range of trajectories that exist as a result of the sun's influence are computed and analyzed. The results are then classified by type, and trades between different measures of cost are discussed.
