                         body to gain or lose energy from its gravitational field. The 
                         present work studies Swing-By maneuvers that are combined with the 
                         use of an impulsive thrust in different directions during the 
                         passage of the spacecraft by the periapsis of its trajectory 
                         around the Moon. The main objective of this type of maneuver is 
                         the fuel economy for orbital transfers. From the results, it is 
                         visible that the best direction to apply the impulse is not the 
                         direction to the motion of the spacecraft, as might be expected. 
                         In fact, by using a different direction, it is possible to 
                         maximize the effects of the Swing-By by decreasing the periapsis 
                         distance and/or increasing the turning angle of the maneuver, that 
                         are the key parameters to specify the variation of energy due to 
                         the Swing-By. The changes in the periapsis distance and turning 
                         angle cause modifications in the geometry of the original 
                         Swing-By, generating a maneuver with new parameters. This new 
                         Swing-By compensates for the loss of energy transfer that results 
                         of applying the impulse in a in a non-tangential direction.",
