                         major goal of future missions is to find solutions that minimize 
                         costs. Our study presents the use of solar radiation pressure, by 
                         varying the area-to-mass ratio and/or the reflectivity coefficient 
                         of the spacecraft, with the goal to assist in the ejection of the 
                         spacecraft from an orbit around an asteroid, for a possible return 
                         phase to the Earth or to direct the spacecraft to a second target. 
                         The asteroid Didymos, which has a small natural moon (Didymoon), 
                         is chosen as the focus of the present study, because it is the 
                         target of the AIDA mission. The study showed the existence of 
                         small but important escape windows from the asteroid using the 
                         solar radiation pressure to eject the spacecraft from the system. 
                         The results also showed: Survival regions between L4 and L5, with 
                         small escape regions nearby, a very large natural ejection zone 20 
                         km away from the surface of Didymos, areas of survival near the 
                         surface of Didymos caused by resonances and the identification of 
                         a chaotic region ranging from approximately 1.2 km to 20 km from 
                         the surface of Didymos.",
