Waste-to-Soil: Astronaut Waste Could Grow Crops on Mars
Researchers weathered lunar and Martian regolith with waste-derived effluent from NASA’s bio-regenerative life-support system (BLiSS), releasing nutrients like sulfur, calcium, and magnesium that could help convert in-situ materials into soil-like growth media for crops on the Moon or Mars—though real regolith lacks some nutrients and the approach still needs refinement.
