This research focuses on identifying low-thrust optimal trajectories for inserting satellites into a Distant Retrograde Orbit (DRO) around the Moon with minimum propellant usage, contributing to cost-effective strategies and enabling heavier payloads for future cislunar missions. This study is motivated by the growing interest in establishing a scientific presence in cislunar space, with initiatives aiming to position orbital stations on such orbits, or to utilize lunar resources and create a launchpad for missions to Mars and beyond. NASA’s Artemis program is heading in this direction. Among potential locations, Periodic Orbits around Lagrangian Points, including DROs and Near-Rectilinear Halo Orbits (NRHOs), present promising options.
