             abstract = "This study applies a new approach, the Theory of Functional 
                         Connections (TFC), to solve the two-point boundary-value problem 
                         (TPBVP) in non-Keplerian orbit transfer. The perturbations 
                         considered are drag, solar radiation pressure, higher-order 
                         gravitational potential harmonic terms, and multiple bodies. The 
                         proposed approach is applied to Earth-to-Moon transfers and 
                         obtains exact boundary condition satisfaction and with very fast 
                         convergence. Thanks to this highly efficient approach, perturbed 
                         pork-chop plots of Earth-to-Moon transfers are generated, and 
                         individual analyses on the transfers parameters are easily done at 
                         low computational costs. The minimum fuel analysis is provided in 
                         terms of the time of flight, thrust application points, and 
                         relative geometry of the Moon and Sun. The transfer costs obtained 
                         are in agreement with the literatures best solutions and in some 
                         cases are even slightly better.",
