China’s space program is entering a bold new phase, with ambitious plans to use the Moon’s own resources for construction. With increasing global interest in lunar exploration, one of the new priorities is to build directly on the Moon using materials found there. Leading this charge, China aims to turn lunar regolith—also known as moon dust—into building blocks using a cutting-edge solar-powered 3D printing technology. This approach could drastically change the way we think about space infrastructure, turning a potential obstacle into an asset for off-world construction.
