Resumo
The present work describes an Earth-to-Earth mission with a lunar flyby: initially, the spacecraft is at a low Earth orbit and it is desired to perform an orbital transfer assisted by a lunar flyby to another orbit around the Earth with a different inclination. In order to solve the transfer problem, two models are considered: the first one is based on a tridimensional patched-conic approximation, and, the second one is based on the spatial circular restricted three-body problem (SCR3BP).
