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. %@area ETES %@electronicmailaddress allan.junior@inpe.br %@electronicmailaddress hunterjohnston@tamu.edu %@electronicmailaddress leakec@tamu.edu %@electronicmailaddress mortari@tamu.edu %@documentstage not transferred %@group CMC-ETES-DIPGR-INPE-MCTI-GOV-BR %@usergroup simone %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Texas A&M University %@affiliation Texas A&M University %@affiliation Texas A&M University %@versiontype publisher %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S} %@doi 10.1140/epjp/s13360-021-01151-2 %2 sid.inpe.br/mtc-m21c/2021/03.04.16.41.44
