Blueprint for a Robotic Lunar Helium-3 Mining Farm: Fuel Supply for Aneutronic Fusion Propulsion

This work introduces the first complete blueprint for a robotic lunar Helium-3 mining farm, specifically engineered to supply aneutronic fusion propulsion. The design combines: Autonomous excavation and haulage robots adapted for lunar dust and low gravity. Foldable solar concentrator arrays powering thermal ovens at ~700 °C to release volatiles. Gas capture and cryogenic isotope separation for He-3 recovery. Modular cryogenic storage tanks and robotic lander systems for orbital export. Redundancy through swarm robotics and in-situ 3D-printing of spare parts. Backup modular nuclear power for lunar night operations. The paper outlines throughput estimates, scalability, and integration with existing launch infrastructure. It addresses the major engineering challenges (dust, construction, scaling, power, reliability) and proposes realistic solutions based on current technology. This blueprint complements the previously published “Blueprint for a Deuterium–Helium-3 Magneto-Inertial Fusion Rocket” (DOI: 10.5281/zenodo.17000203), together establishing the world’s first interstellar propulsion architecture: a fusion rocket and its lunar fuel supply chain.
