This Is What The First Lunar Base Could Really Look Like

We have seen many concepts, but this is the most realistic plan yet for humanity’s first Moon Base. It will be more efficient and cheaper to build than any other alternative, as it uses 3D printing to quickly transform raw lunar soil into habitable domes.

Also? It looks awesome.

The lunar soil structure will provide both radiation and temperature insulation. Inside, a lightweight pressurised inflatable with the same dome shape will be the living environment for the first human moon settlers.

The European Space Agency and architectural firm Foster + Partners are now working on the technology to make this a reality. According to ESA’s human spaceflight team’s Scott Hovland: “3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth.”

The logic is that if 90 per cent of the stuff we need to build the base is already on the moon, we only have to ferry the 3D-printing robots (you can look at one below) and the lightweight parts, like the inflatables and the solid connector and entry segments. This will make this idea a lot cheaper than the alternatives.

Xavier De Kestelier of Foster + Partners Specialist Modelling Group says that their construction 3D-printing technology has already produced entire structures under extreme conditions on Earth, so it’s perfectly reasonable to do the same up there:

As a practice, we are used to designing for extreme climates on Earth and exploiting the environmental benefits of using local, sustainable materials. Our lunar habitation follows a similar logic.

The team has already came up with a way to use the same technologies under the Moon’s environmental conditions, devising “a weight-bearing ‘catenary’ dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a pressurised inflatable to shelter astronauts. A hollow closed-cell structure — reminiscent of bird bones — provides a good combination of strength and weight.” They produced this 1.4-tonne sample as a demonstration of how these hollow cell walls would work:

That block is all built with simulated lunar material and magnesium oxide. That turns the moonstuff into a pulp that can be sprayed to form the block. Then, they apply a binding salt that “converts [this] material into a stone-like solid.” Quite impressive.

According to Enrico Dini — the founder of UK-based Monolite, the company that builds the 3D building printers — they are now printed at 2m per hour. He says that their next generation will speed up to 3.5m per hour, which is enough to complete an entire building in one week.

If they keep up that kind of progress, a full structure on the moon will be a reality within our lifespans.
