Tisserand-leveraging transfers (TILTs) are introduced as a new method for computing low- orbit transfers with the help of third-body perturbations. The TILTs can mitigate the costs and risk of planetary missions by reducing the orbit insertion maneuver requirements while maintaining short flight times. TILTs connect two flybys at the minor body with an impulsive maneuver at an apse. Using the circular, restricted three-body problem, TILTs extend the concept of -infinity leveraging beyond the patched-conics domain. In this paper, a new method is presented to compute TILTs and to patch them together to design low-energy transfers. The presented solutions have transfer times similar to the high-energy solutions, yet the cost is significantly reduced. For this reason, TILTs are used in the reference endgame of ESA’s new mission option to Ganymede, JUICE, which is also presented here. JUICE’s low-energy endgame halves the cost of similar high-energy endgames, which makes TILTs a mission-enabling technology for JUICE. The “lunar resonances” of SMART-1 are also explained in terms of low-thrust TILTs, suggesting future application of TILTs and low-thrust TILTs to design missions to the Moon and to other small-body destinations.
