abstract = "The formation of our Solar System and planetary defense strategies
are among the priorities to be investigated in the next years by
the space science community. As in-situ missions to small bodies
(as comets and asteroids) are options to conduct these
investigations, this paper proposes a combination of methodologies
to produce low-cost transfers to near-earth asteroids (NEAs).
Low-cost trajectories derived from retrograde periodic orbits
around L1 are taken as a starting point for the escape of the
Earth-Moon system and, as the vehicle exits the sphere of
influence of Earth, the deployment of an adjustable solar sail
guarantees the interception of the target in a predetermined
position and time of flight. Different sail loadings (164, 61 and
30 g/m2) are tested and a case study to the NEA 65,803 Didymos is
presented. The results show economies in the velocity increments
required by the mission up to 8.48%, although a longer time of
flight might be needed depending on the sail loading.",
