Transfer Time

Definition

The time required to travel along the stable manifold from the lunar surface to the vicinity of a libration point orbit (~70-90 km from the reference orbit). Direct transfers take approximately 10 days, with about 5 days devoted to the asymptotic approach phase (velocity below 0.25 km/s within 1000 km of the halo orbit). Each additional lunar loop adds roughly 10 days.

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.
