One of the options is the use of a “gravity assisted” maneuver, which is a technique where a spacecraft passes close to a celestial body and uses the gravity of this body to change its trajectory. This approach trajectory has symmetry with respect to the periapsis line when observed from a reference frame fixed in the approached body. There is also a more complex maneuver, when the passage by the celestial body is combined with the application of propulsion, either to give extra energy to the spacecraft or to help to satisfy other constraints required by the mission, like passing by a giving point or region in space. The main object of this study is to measure the efficiency of the application of a continuous thrust combined with the “gravity assisted” maneuver. The effect of this combination is analyzed using maps that give the energy variation of the spacecraft as function of the parameters related to the maneuver. This analysis is made from the point of view of the variation of energy of the spacecraft with respect to the main body of the system. The continuous thrust is applied in the different regions of the trajectory to evaluate the effects of the locations of the thrusting arcs in the variations of energy. The effects of the variations of the direction of the thrust are also studied. This type of combined maneuver may be used to give extra energy to the spacecraft and keeping control of the trajectory during the close approach to better position the spacecraft to complete the mission. 000119966 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/E24-20R$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/ESP2017-87113-R 000119966 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000119966 590__ $$a2.7$$b2022 000119966 592__ $$a0.483$$b2022 000119966 591__ $$aMULTIDISCIPLINARY SCIENCES$$b36 / 73 = 0.493$$c2022$$dQ2$$eT2 000119966 593__ $$aChemistry (miscellaneous)$$c2022$$dQ2 000119966 593__ $$aPhysics and Astronomy (miscellaneous)$$c2022$$dQ2 000119966 593__ $$aMathematics (miscellaneous)$$c2022$$dQ2 000119966 593__ $$aComputer Science (miscellaneous)$$c2022$$dQ2 000119966 594__ $$a4.9$$b2022 000119966 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000119966 700__ $$0(orcid)0000-0001-5208-4494$$aElipe, Antonio$$uUniversidad de Zaragoza 000119966 700__ $$aDe Moraes, Rodolpho V. 000119966 700__ $$aPrado, Antônio F.
