No matter where we go in the universe, we’re going to need water. Thus far, human missions to Earth orbit and the moon have taken water with them. But while that works for short missions, it isn’t practical in the long term. Water is heavy, and it would take far too much fuel to bring sufficient water to sustain long-term bases on the moon or Mars. So we’ll have to use the water we can extract locally.

Fortunately, water is a common molecule in the universe. Even the moon has plenty of water to sustain a lunar colony. The only real challenge is how to extract it. As a recent study published in Acta Astronautica shows, that might be as easy as popping things into a microwave oven.

Benefits of nitrogen-fixing bacteria could aid efforts towards farming soils on Mars. Clover plants grown in Mars-like soils experience significantly more growth when inoculated with symbiotic nitrogen-fixing bacteria than when left uninoculated. Franklin Harris of Colorado State University, U.S., and colleagues present these findings in the open-access journal PLOS ONE on September 29, 2021.

As Earth’s population grows, researchers are studying the possibility of farming Martian soils, or “regoli...

Researchers have discovered a system of ridges spread across the nearside of the Moon topped with freshly exposed boulders. The ridges could be evidence of active lunar tectonic processes, the researchers say, possibly the echo of a long-ago impact that nearly tore the Moon apart.

“There’s this assumption that the Moon is long dead, but we keep finding that that’s not the case,” said Peter Schultz, a professor in Brown University’s Department of Earth, Environmental and Planetary Sciences and co-author of the research, which is published in the journal Geology...

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...
