What conditions are required for the successful cultivation of spirulina on a spacecraft?
Answer
Precise lighting, controlled temperature, and a steady nutrient supply
Cultivating algae in space is a delicate process that requires maintaining specific environmental parameters. If the temperature fluctuates or the lighting conditions are not consistent, the algae may die or lose its nutritional profile. A steady supply of nutrients is also necessary for the culture to thrive. Successfully managing these conditions is a major technological hurdle for creating sustainable, self-sufficient food systems on long missions.
