Moon settlements could use brick-repairing bacteria for long-lasting habitats

Researchers at the Indian Institute of Science developed a method to repair and strengthen lunar soil bricks using a mixture of Sporosarcina pasteurii bacteria, guar gum, and simulated lunar soil. This bacterial slurry repairs defects and restores brick strength, potentially extending the lifespan of lunar structures. The repaired bricks can withstand temperatures between 100°C and 175°C, addressing challenges posed by the Moon's harsh environment. This development could support long-term lunar settlements planned by space agencies.
