Definition
A maneuver-free transfer that exploits the stable manifold of a libration point orbit. In the Sun-Earth system, spacecraft can travel from near-Earth to the libration point orbit along the stable manifold tube without maneuvers. In the Earth-Moon system, such transfers are available from low lunar orbit but not from near-Earth.
Application Value
This concept has practical applications in cislunar space science and engineering. Related research supports the planning, implementation, and operations of cislunar missions, forming an integral part of the knowledge system in this field.
