Calculating low-energy low-thrust (LE-LT) trajectories that join Earth orbits to lunar orbits in the circular restricted three-body (CR3B) model involves designing the spiral thrust arcs around the primaries on both ends. Existing methods are computationally expensive, involve providing hard-to-obtain initial guesses and do not lend themselves well to quick parametric trade studies. In this paper, two methods are discussed to explore the solution space for designing the Earth-Moon LE-LT transfers and their results compared against each other. The first uses a modified low-thrust feedback control law (Q-law) to design the spiral thrust arcs, while the second patches a tangential thrust arc with a Finite Burn Low Thrust (FBLT) arc to place the spacecraft onto the invariant manifold of the desired halo orbit.
