Algae have many properties that make them ideal organisms to support humans during long-duration spaceflight missions. Not only could they serve as a nutritional source included in astronaut menus, algae could also remove carbon dioxide and produce oxygen for spacecraft environmental control systems, help regulate spacecraft temperatures, recycle certain wastes, and even act as a source of fuel. The data generated from this experiment will be used to advance the development of microalgal life support systems for space missions and could impact the design of future carbon dioxide capture, oxygen conversion, wastewater treatment systems, and provide fertilizer options for other agricultural crops grown in space.
