lunar regolith – Impact Lab

The dream of building and repairing hardware directly in space just took a giant leap forward. A research team at Leibniz University Hannover has successfully demonstrated, for the first time, 3D printing with metal powder in microgravity. This is more than a technical milestone—it’s a glimpse at how the very logistics of space exploration could be rewritten.

For decades, one of the biggest bottlenecks in human expansion beyond Earth has been our dependence on Earth-bound supply chains. Break a part on Mars or the Moon, and you either pack spares in advance or face disaster. Now imagine astronauts simply fabricating new titanium or nickel components on the spot. That’s what Hannover’s team just tested—laser-based metal deposition adapted for the chaotic environment of zero gravity.

ESA’s technical heart has begun to produce oxygen out of simulated moondust.

A prototype oxygen plant has been set up in the Materials and Electrical Components Laboratory of the European Space Research and Technology Centre, ESTEC, based in Noordwijk in the Netherlands.

“Having our own facility allows us to focus on oxygen production, measuring it with a mass spectrometer as it is extracted from the regolith simulant,” comments Beth Lomax of the University of Glasgow, whose Ph.D. work is being supported through ESA’s Networking and Partnering Initiative, harnessing advanced academic research for space applications.

“Being able to acquire oxygen from resources found on the Moon would obviously be hugely useful for future lunar settlers, both for breathing and in the local production of rocket fuel.”
