Robotic excavator prototype targets autonomous moon base construction

Astroport Space Technologies and Venturi Astrolab have recently demonstrated a prototype robotic excavator designed to support autonomous construction on the Moon, marking a significant step toward establishing permanent lunar bases. The excavator, integrated with Astrolab’s Flexible Logistics and Exploration (FLEX) rover—a modular platform capable of swapping payloads—successfully moved 94 kg of lunar regolith in 3.5 minutes during field tests. This technology aims to prepare the lunar surface by creating sintered landing pads and roads from moon dust, addressing the challenge of damaging dust plumes generated by spacecraft landings. The partnership’s broader goal is to develop a suite of automated tools to build essential lunar infrastructure before large-scale human missions arrive. By prioritizing the construction of stable “ports” and roadways, they seek to provide NASA and the Space Force with ready-to-use capabilities that ensure mission safety and sustainability. This modular approach could enable precise excavation for habitats, pave supply routes, and mitigate hazards posed by reg
