【 摘 要 】

In this work we have studied transferences between the Earth and the Moon considering bi- and tri-impulsive conventional maneuvers (like Hohmann) in order to make the acquisition of trajectories which are captured by the Moon's gravitational field through the Lagrangian equilibrium point L1. Results show that these transfer models offer reduction in the ΔVTotalof the mission. However, they do not require long transfer times.
