Gravitational Superhighway

Definition

A network of low-energy transport channels formed by invariant manifolds in cislunar space. Wright et al. found that trajectories entering cislunar space via L1/L5 naturally converge at 'throat points,' and invariant manifolds can capture over 80% of cislunar traffic flow, providing theoretical basis for SSA search volume pruning.

Application Value

This term在cislunar space missions中has important application value. In orbit design, it can be used foroptimizing transfer trajectories, reducing mission fuel consumption. In attitude control and dynamics analysis, it helps understandthe motion characteristics of spacecraft in complex gravitational fields, providing theoretical support for mission planning. In navigation and orbit determination, methods based on this termcan improve orbit prediction accuracy, supporting the development of autonomous navigation algorithms.
