                         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.",
