Abstract
The growing interest in exploiting extraterrestrial resources has spotlighted asteroid retrieval missions as a pivotal strategy for resource utilization and planetary defense. This study proposes a non-destructive retrieval approach by rendezvousing with Near-Earth Asteroids (NEA) and utilizing guided propulsion to move part of its mass closer to Earth in order to allow in-orbit production of spacecraft components without launching them from Earth making spacecraft construction less expensive. From the JPL Small Bodies Database, a refined selection of asteroids is idendtified through a Pareto front analysis that searches for bodies that have the best orbital parameters’ proximity to those matching the departure point, at the Sun-Earth Lagrange Point L2.
Optimal low-thrust trajectories via indirect methods based on the Optimal Control Theory are determined for the spacecraft to rendezvous with the asteroids
