New L1 Route Cuts Moon Transfer ?v by 60 m/s

Summary

Story summary

Scientists uncovered a hidden Earth-Moon route via the L1 point that cuts ?v by nearly 60 m/s after simulating millions of trajectories.
Allan Kardec de Almeida Júnior’s international team used the Theory of Functional Connections to evaluate about 30 million routes, declaring the path the most fuel-efficient Earth-to-Moon trajectory to date.
The optimal Lyapunov orbit around L1 offers continuous communication, minimal station-keeping thrust, and a 32-day travel time suitable for non-urgent cargo.
