Scientists plan to use Lego-inspired ‘space bricks’ to build homes on the Moon

The European Space Agency (ESA) is exploring an innovative approach to building structures on the Moon by transforming space dust into Lego-like bricks, according to space.comThe innovative idea aims to address the challenges of building on the lunar surface by relying on modular, interlocking bricks that can be easily transported and assembled in space. It will also be a cost-effective solution since astronauts will use materials found on the lunar surface, the outlet added.

The concept of Lego lunar bricks

ESA aims to make bricks from lunar regolith, a loose, fragmented material that covers the Moon’s surface. Using a 3D printing technique called sintering, which involves heating the regolith just below its melting point to fuse the particles together, ESA can produce robust bricks directly on the Moon. This process reduces the need to transport heavy building materials from Earth, significantly reducing costs and logistical challenges.

Advantages of modular construction

One of the main advantages of using Lego-like bricks for lunar construction is their modularity. Much like traditional Lego bricks, these lunar bricks can be easily connected and reconfigured, allowing for flexible and scalable building designs. This flexibility is essential for adapting to the Moon’s harsh and unpredictable environment. Additionally, modular construction can speed up the construction process, allowing astronauts to quickly assemble and disassemble structures as needed.

The process of sintering regolith to create bricks will also ensure the structures are strong and able to withstand the extreme conditions on the Moon. The interlocking design of the bricks also improves structural stability, which is essential for long-term lunar habitats and research facilities.

Developing lunar housing is an increasingly important goal for space agencies around the world. The American space agency NASA has developed the Artemis program, with the goal of having humans inhabiting lunar residences by 2040. The most important part of the Artemis program is the Lunar Homestead project, which aims to develop the architecture of habitable structures to facilitate prolonged human presence and scientific efforts on the Moon.
