Abstract

The purpose of this research is to investigate the orbital evolution as a function of the spacecraft around Mars, considering different types of orbits for the vehicle space. In this study, numerical integrations will be made using the Mercury N-bodies (Chambers, 1999) to obtain the orbital evolution of the satellite as a function of time. Using the perturbation integral model, an analysis of the integral of the orbits aiming to find the orbit that suffers the least disturbance with respect to the model considered. Orbits considered stable will be considered those that suffer the orbit minimal deviation, within certain limits, of its nominal orbit during the total time of integral. (AU)
