             abstract = "Near-Earth Asteroids (NEA) tell us a lot about the early Solar 
                         System. Space missions aimed to those objects can provide 
                         information for a better understanding of physical and chemical 
                         processes of Earth's formation. In this perspective, it is 
                         necessary to invest in optimized techniques orbital transfer able 
                         to achieve these objects with reduced spent fuel. In this paper, 
                         we explore the dynamics of unstable periodic orbits around the 
                         Lagrangian point L1 and the gravitational influence of the moon in 
                         order to get the energy needed to overcome the gravity of the 
                         Earth-Moon system and reach a NEA. The fuel consumption in this 
                         kind of maneuver is less than that required in other approaches. 
                         The escape trajectories obtained present sensitive dependence on 
                         initial conditions and can be judiciously controlled by small 
                         perturbations so that they are targeted to specific regions of the 
                         Solar System, being propitious mainly for missions whose targets 
                         belong to Apollos and Atens classes.",
