To break down asteroids into a nutritional biomass, we could utilize beneficial bacteria, turning carbon-rich materials in space into edible food for astronauts.
Inspired by a project to recycle military rations, the team applies methods to convert plastic through pyrolysis, which could similarly work to reconstitute asteroids.
Before proposing asteroid-based food, scientists acknowledge challenges, including uncertainty about the toxicity of biomass and the technical barriers to asteroid mining.
The concept is not to eat rocks directly, but transform them via chemical processes into a form of sustenance for future deep space missions.
