We’ve long known that to build a habitat on the Moon or Mars, we’d have to use in-situ resources. That means building buildings and even colonies with material found on site.
The promise of 3D printing makes this feel very possible. Now, people are moving ahead with prototype printing using similar material that is found here on earth.
But what about printing with actual space-material?
The European Space Agency has used a meteorite that fell to earth 20 years ago, and turned it into dust that was then used to print LEGO-style bricks.
The bricks show that printing with real space rocks can be a viable option for potentially building structural components using dust from the Moon or Mars. These special LEGOs are on display at LEGO’s headquarters, inspiring the next generation of builders, and potentially space travelers.
