Earth-to-Halo Transfers in the Sun–Earth–Moon Scenario?

Abstract: Trajectories connecting LEOs with halos around libration points of the Earth– Moon CRTBP are presented. Exploiting the coupled circular restricted three-body problem approximation suitable first guess trajectories are derived detecting intersections between stable manifolds related to halo orbits of EM spatial CRTBP and Earth-escaping trajectories integrated in planar SE CRTBP. The accuracy of the intersections in configuration space and the discontinuities in terms of ∆v are controlled through the box covering structure implemented in the software GAIO. Finally first guess solutions are optimized in the bicircular four-body problem and single-impulse and two-impulse transfers are presented
