Searching for Less-Disturbed Orbital Regions Around the Near-Earth Asteroid 2001

The Aster mission is the first proposed Brazilian deep space mission. The target is the triple near-Earth asteroid (153591) 2001 SN263. This work searches for less-disturbed orbital regions to place a spacecraft around this asteroid, considering the gravity forces and the solar radiation pressure. Used in this study are the standard maps showing the duration of the orbits and the method of the integral of the disturbing accelerations to generate perturbation maps for this system. These maps can provide information about the less-disturbed orbital regions and the fuel consumption, in terms of Δv, to keep a spacecraft as close as possible to a Keplerian orbit in this system. The results of this work can be used for the planning of the Aster mission, as well as other missions to this interesting triple system.
