European Space Agency to build lunar structures using Lego-inspired 'space bricks' from lunar regolith

This is a cost-effective strategy because it relies on materials readily available on the Moon, reducing the need to transport heavy construction materials from Earth.

THE European Space Agency (ESA) is pioneering a new approach to building structures on the Moon by converting the lunar surface regolithor space dust, made of Lego-like bricks. This innovative method, reported by space.com, aims to address the challenges of building on the lunar surface by using modular, interlocking bricks that can be easily transported and assembled in space. It is a cost-effective strategy because it relies on materials readily available on the Moon, reducing the need to transport heavy building materials from Earth.

The process involves creating bricks from lunar regolith using a 3D printing technique called “sintering.” Sintering involves heating the regolith to just below its melting point, which fuses the particles together to form sturdy bricks. Producing bricks directly on the Moon significantly reduces transportation costs and logistical challenges.

One of the main advantages of using them LegoLunar Bricks are distinguished by their modularity. They assemble and reconfigure in the same way as classic Lego bricks, allowing for flexible and scalable building designs. This adaptability is essential for dealing with the harsh and unpredictable environment of the Moon. In addition, modular construction speeds up the construction process, allowing astronauts to quickly assemble and disassemble structures as needed.

The sintering process ensures that the bricks are strong enough to withstand the extreme conditions of the Moon. The interlocking design of the bricks improves structural stability, which is essential for the long-term viability of lunar habitats and research facilities.

The idea of building homes on the Moon is gaining traction among space agencies around the world. NASA’s Artemis program, for example, aims to establish human residences on the Moon by 2040. A central element of this program is the Lunar Homestead Project, which aims to develop the architecture of habitable structures to support a prolonged human presence and scientific activities on the Moon.

By exploiting local materials and innovative construction techniques, ESA’s approach could pave the way for sustainable human habitation on the lunar surface.
