Definition

An Earth-to-moon transfer accomplished entirely by gravitational forces without mid-course propulsive maneuvers. It encompasses both direct transfers (a few days) and low-energy transfers (tens to over 100 days) that exploit multibody dynamics.

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.
