Could Future Astronauts 3D Print Habitats Using Mars and Moon Soil?
Right now, there are dozens of theoretical proposals for how humans could eventually populate
, if you'll remember, is the Dutch non-profit that made news this year when it put out a
call for applications for potential astronauts
Or, we could just go underground. That's the concept behind this plan by Russian architects
. Here's the bare bones version: A series of robots-equipped with the ability to dig-would identify weak areas in the Martian soil and carve them out. Then, using a process similar to that of structural

This spring, the European Space Agency-an organization that's far more likely to actually reach the Red Planet-revealed a conceptual study that's not dissimilar from this proposal. Developed in partnership with the architects Norman Foster and Partners, the project studied the feasibility of lugging an army of 3D printers to the Moon, where they could be used to print shelters for the first semi-permanent inhabitants.
Of course, we're a long ways off from either of these ideas being plausible. For one thing, the weight of these printers would be prohibitive. But what does make sense? Taking the weight of conventional materials out of the equation. The precious tons saved from not shuttling steel habitats from Earth to space is the crucial insight here. Barring our ability to seek out natural saves on the surface of Mars, structural 3D printing might just be our best bet. [
