Irish scientists have discovered that Martian sand can be used for construction in space

Researchers from Trinity College in Dublin (Ireland) have developed a method to convert Martian and lunar sand into durable bricks for future space settlements.

The scientists created a technology that binds regolith—loose rocks, sand, and dust from the surfaces of Mars and the Moon—using carbon nanotubes. This process requires low temperatures and minimal energy consumption, making it efficient for space applications.

Despite having a relatively low density, these blocks exhibit strength comparable to granite. The strongest bricks made using this method have a compression strengthCompression strength is the material's or structure's ability to withstand compressive loads without failure or significant deformation. of 100 MPa, which surpasses that of some top terrestrial concretes.

A key advantage of these regolith bricks is their electrical conductivity. This allows them to serve as internal sensors for monitoring the structural integrity of extraterrestrial buildings, capable of detecting early signs of damage in airtight space structures.

The findings of this research are significant not just for the space industry. The scientists believe their discoveries may find practical applications in the construction industry on Earth. Adding a nanomaterial like graphene to concrete could enhance its strength by 40%. This could potentially reduce the amount of concrete needed and decrease pollution from the concrete industry, which currently accounts for nearly 8% of global CO2 emissions.

Previously, researchers from the University of Central Florida also explored the potential of using lunar regolith to create bricks for space construction projects. They developed 3D-printed bricks made from lunar regolith that can withstand the extreme conditions of space.
