This paper presents 'an approach to obtain low energy interplanetary transfers based on the technique of the intersecting manifolds. At first, a full four-body model is divided into two three-body problems having the Sun and an inner planet as primaries. Then, manifolds that do not intersect are linked considering a Lambert's or a low thrust arc, obtained within an intermediate two-body model. The proposed patching conic-manifolds method exploits the two gravitational attractions of the bodies involved to change the energy level of the spacecraft and to perform a ballistic capture (at arrival) and a ballistic repulsion (at departure). Some examples have been computed to validate this approach for the design of transfer trajectories among the inner planets.
