'Building cities on the Moon': Chinese scientists develop machine to turn lunar dust into bricks


The device operates like a 3D printer but replaces conventional heat sources with concentrated solar energy.

China’s Deep Space Exploration Laboratory (DSEL) in Hefei, Anhui Province, has developed a solar-powered device capable of transforming lunar regolith, the Moon’s loose surface material, into durable construction bricks. Senior engineer Yang Honglun notes that while lunar bricks cannot maintain internal pressure in the Moon’s vacuum, they can serve as protective shells around pressurised habitat modules. The approach aligns with global ambitions to establish long-term human presence on the Moon, with the United States pursuing parallel efforts through NASA’s Artemis programme.
