Artificial photosynthesis could be the solution to the limited oxygen supply for astronauts during space exploration, especially on long-duration missions like a one-way trip to Mars. Currently, most of the oxygen on the International Space Station is obtained through electrolysis, but the process is limited by the amount of water that can be carried. Artificial photosynthesis could provide a sustainable source of oxygen by using sunlight to convert carbon dioxide into oxygen.
Researchers have proposed using artificial photosynthesis to create a new type of life support system for space exploration. The system would rely on semiconductor materials coated with metallic catalysts to convert CO2 and water into oxygen gas and hydrogen/carbon-based fuels. This would be highly beneficial for long-duration missions since it would combine reduced volume and weight with greater efficiency. Furthermore, the system would be easier to maintain since it would need less complex wiring and mechanical components.
