Artificial Photosynthesis: Key to Thriving in Space.

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. The technology is still in its infancy and requires several more years of additional research, but the potential returns would be immense, ranging from lightweight life support systems for long-duration missions to artificial atmospheres for habitats in LEO, on the Moon, and on Mars.
