College student develops LEGO-like, 3D-printed moon bricks

A permanent lunar base will require structures resilient enough to withstand everything from cosmic radiation and micro-meteorites to moonquakes. There are plenty of building materials to choose from on Earth, but they all come with a catch: transportation storage aboard spacecraft is limited, and each additional pound of cargo will quickly ramp up costs. Engineers have spent years experimenting with ways for future astronauts to source local lunar ingredients, including fine moon dust known as
