Researchers are exploring how these unconventional ingredients could hold the key to brewing and building habitats on the red planet. While space exploration typically relies on heavy transported materials, these biological substances offer potential alternatives for in-situ resource utilization. The testing forms part of broader strategies to colonize Mars following initial efforts on the Moon.Why it mattersBuilding sustainable habitats is a primary hurdle for crewed miss
