Definition

A spacecraft concept that visits multiple moons sequentially, using low-energy passageways to transfer between moons with minimal propellant.

Application Value

The multi-moon orbiter concept fully exploits natural dynamics channels in multi-body systems, such as invariant manifolds and resonance corridors, to transfer between multiple moons at extremely low propellant cost. In Jupiter's Galilean moon system, such a spacecraft can sequentially flyby Io, Europa, Ganymede, and Callisto, with each transfer utilizing low-energy corridors rather than conventional impulsive maneuvers. This concept is equally applicable to Saturn's multi-moon system, enabling close flyby or landing reconnaissance of multiple moons within a limited propellant budget. The multi-moon orbiter design approach also holds significant reference value for future asteroid multi-target sample return missions in cislunar space.
