The Moon's surface is covered with a layer of material called regolith, which is fragmented by meteorite impacts over billions of years. This abundant resource offers a potential solution to construction needs.

However, collecting actual regolith on the Moon is a challenge. To overcome this limitation, scientists from the European Space Agency (ESA) have created an artificial version of lunar regolith by crushing a 1-year-old meteorite. This material is then used to 3D print Lego-style bricks, which the ESA calls “space bricks.”

The space bricks are designed to be easily assembled, providing flexibility in building different structures. The bricks have a rough texture and are grey in colour, and have been tested in a simulated lunar environment. ESA space engineers are continuing to refine their construction methods ahead of actual lunar missions.

The ability to build habitats and other necessary infrastructure on the Moon could significantly reduce the need for supplies from Earth, making exploration and longer stays on the Moon and ultimately creating lunar habitats more feasible.
