Multiple Sun-Earth Saddle Point flybys for LISA Pathfinder

► LISA Pathfinder, future ESA mission, has the capacity to test gravitational theories. ► To do so, it has to fly by the Earth-Sun saddle point, from L1, its actual station. ► Such a trajectory is feasible with only a few, small manoeuvres. ► To enhance the science return, it is even possible to fly by the saddle point twice.
