How 3D Printing and Living Organisms Could Build the Future on Mars

What if future Mars habitats could be 3D-printed using materials grown and gathered on the planet itself?Researchers have developed a bio-based construction material combining Martian regolith, gelatin, and genetically engineered yeast that could form structures as strong as concrete. Still tested only in simulated conditions, the technology could point toward a more sustainable and recyclable way to build future colonies on Mars.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
