             abstract = "The main objective of the present paper is to find the 
                         modifications that a tethered slingshot maneuver (TSSM) can make 
                         in the orbit of a spacecraft, both in terms of energy and 
                         inclination. The TSSM is a maneuver where a tether fixed in a 
                         celestial body, like a moon or an asteroid, makes a rotation in 
                         the velocity vector of a spacecraft to modify its orbit. In 
                         particular, the present paper concentrates in showing the 
                         potential savings in fuel consumption for orbital maneuvers that 
                         use this technique in an elliptic system of primaries, which gives 
                         advantages over the circular problem. To make this study more 
                         complete, analytical approximations are derived to provide a 
                         general view of the behavior of the maneuver in terms of 
                         variations of energy and inclination as a function of different 
                         conditions for the geometry, length, and location of the tether. 
                         Among the main results, it is showed the best location to place 
                         the tether and the best moment and duration to perform the 
                         maneuver, as a function of the parameters involved, like the 
                         orbits of the primaries, the incoming velocity of the spacecraft, 
                         etc. The solutions are shown in maps giving the variations of 
                         energy and inclination for different locations of this device and 
                         assuming different incoming orbits for the spacecraft. Regions 
                         that maximize those variations are indicated. Based on those 
                         results, it is possible to find the best solution for several 
                         particular problems. The results show that this maneuver has a 
                         large potential to be explored, helping a spacecraft to make 
                         journeys to the exterior planets and out of the Solar System. 
                         Those results are arguments in favor of developing efforts to 
                         solve the technological problems involved in real applications of 
                         this technique. The main advantage of the proposed technique is 
                         the energy gain given by the maneuver, in particular when using 
                         the higher velocity of the asteroid, at the periapsis of its orbit 
                         around the Sun. The main disadvantages are the technical 
                         challenges involved in the implementation of the maneuver and the 
                         fact that to get maximum benefits, there are time restrictions to 
                         apply the maneuver, because the asteroid must be passing by its 
                         periapsis.",
