With an eye to the probably small quantity of propellant left when its operational life has ended, the spacecraft leaves the libration point orbit on an unstable invariant manifold to bring itself closer to the Earth and Moon. e total trajeory is modeled in the coupled circular restried three-body problem, and some preliminary study of the use of solar radiation pressure is also provided. e concept of survivability and event maps is introduced to obtain suitable conditions that can be targeted such that the spacecraft impas, or is weakly captured by, the Moon. Weak capture at the Moon is studied by method of these maps. Some results for planar Lyapunov orbits at L1 and L2 are given, as well as some results for the operational orbit of SOHO.
