In this paper we search for transfer orbits from one body back to the same body (Henon's problem, see Henon, 1968) in the Earth-Moon system. It is a continuation of a previous research (Prado and Broucke, 1994; Prado, 1993), where this problem was studied for the Earth-Sun system. In particular, we are searching for orbits that can be used in three situations: To transfer a spacecraft from the Moon back to the Moon; To transfer a spacecraft from the Moon to the respective Lagrangian points L(sub 3), L(sub 4), and L(sub 5); and To transfer a spacecraft to an orbit that passes close to the Moon and to the Earth, with the goal of building a transportation system between these two celestial bodies. The model used for the dynamics is the planar and circular restricted three-body problem. The global Lamaitre regularization is used to avoid numerical problems during close approaches. An interesting result that was obtained in this research is a family of transfer orbits from the Moon back to the Moon that requires an impulse with a magnitude lower than the escape velocity from the Moon.
