| Abstract | |
In this study, the dynamics of a space vehicle in the vicinity of a binary system of asteroids is analyzed by modeling one of the primaries as a rotating mass dipole considered to be in a spin-orbit resonance. Different mass distributions for the binary and for the dipole are considered, as well as different dimensional configurations. Then, the influence of such characteristics on the location of the equilibrium points of the system is studied. The zero velocity curves of the system are also plotted, identifying the regions of forbidden and allowed motion for a spacecraft travelling near the system. Finally, several maps are made showing the lifetimes of orbits as a function of their initial conditions, where the end of the life of an orbit is defined as a collision with any of the bodies or an ejection from the system.
