Definition

The flight arc on the central ellipse inside the pseudostate sphere within the approach phase of an Earth-Moon free-return trajectory. Its velocity is obtained by solving Lambert's problem, serving as a key transition between the main elliptical arc and the pseudostate return arc of the approach phase.

Application Value

This concept plays an important role in cislunar space mission design and orbital dynamics analysis.
