abstract = "Asteroids and comets have become the target of space missions. A
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.",
