### Abstract

A technique for the preliminary global optimization of a low-thrust transfer trajectory from Earth orbit to a nominal, collinear Lagrange point orbit in the Earth-moon system is presented. The initial Earth orbit has a Jacobi energy equal to that of a geosynchronous Earth orbit (GEO-energy). Particle swarm optimization (PSO) is utilized to quickly locate the globally optimal "patch-point" where the low-thrust trajectory is terminated and the spacecraft begins to ballistically coast along the stable manifold. The results of the PSO algorithm are compared with that of a stochastic Monte Carlo algorithm.
