Abstract

The objective of the present paper is to study orbital maneuvers to perform a mission to a triple asteroid. First, a genetic algorithm is used to find multi-impulsive maneuvers to go from the Earth to the asteroid, with minimum fuel consumption. After that, swing-by maneuvers with the two smaller bodies of the triple system are simulated and mapped to show the possible gains of energy that can be accomplished with the use of this technique. This study is made using the ``patched conics approximation{''} and the ``restricted three-body problem{''}, to determine the accuracy of the approximated model. The system of asteroids 2001SN is used as an example for the calculations. (AU)
