Manifold Insertion

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

The process by which a spacecraft transitions from a periodic orbit near a libration point onto an invariant manifold. After manifold insertion, the spacecraft can depart the libration point region along a natural low-energy dynamical path.

Application Value

The Manifold Insertion plays a significant role in cislunar space mission design, analysis, and control. In orbital design, it can be leveraged for transfer trajectory optimization; in navigation and control, it improves mission execution precision and reliability; in system analysis, it facilitates deeper understanding of complex multi-body dynamical behavior, guiding mission planning and risk assessment.
