## Resource

Researchers have developed a new computational method to plan missions to near-Earth objects using “invisible highways” shaped by multi-body gravity. By combining near-Earth dynamics with traditional solar models, the system finds ultra-efficient trajectories that minimize fuel—especially suited for solar electric propulsion. Simulations across dozens of asteroids show major cost reductions and safer return paths with lower re-entry speeds, opening a practical route for future exploration and resource missions.
