Scientists at the University of Science and Technology of China are pioneering a novel method for producing oxygen on Mars using solar energy and automated synthesis. With the atmosphere on Mars lacking sufficient oxygen for human sustenance and rocket fuel creation, finding alternative methods of oxygen production is crucial for future missions to the red planet. While NASA’s Perseverance rover successfully extracted oxygen from CO2 in Mars’ atmosphere, Chinese scientists are exploring a different approach.
In a recently published paper, the team details their research on oxygen-producing catalysts using automated synthesis and a robotic AI chemist. By leveraging solar energy and catalysts, the scientists aim to unlock the oxygen potential hidden in Martian water. Unlike traditional electrolysis, which involves running an electrical current through water to produce oxygen and hydrogen, this method relies on optimized catalysts to overcome the limitations of conventional electrolysis.
The challenge lies in identifying the appropriate catalysts available on Mars, given the unique conditions of the planet. Over three million possible catalysts exist on Mars, making manual experimentation impractical due to long communication delays between Earth and Mars. However, by employing robotics and AI, researchers can navigate this vast chemical space and search for the optimal catalyst formula without human intervention.
To conduct their experiments, the scientists utilized Martian meteorites as feedstock. These meteorites served as a readily available source of Martian material, given that China does not currently have a functioning spacecraft on Mars. Through their fully automated system, which includes catalyst synthesis, characterization, and testing, the researchers successfully demonstrated the effectiveness of the AI-driven approach.
Compared to traditional trial-and-error methods, which would require over 2,000 years of human labor to screen the potential catalysts, the robotic AI system significantly accelerates the process. Taking inspiration from previous advancements in robotic chemistry, the researchers highlight the potential for leveraging automation to tackle the challenges of extraterrestrial material discovery and synthesis.
This breakthrough represents a crucial step towards establishing a sustainable oxygen supply on Mars, laying the foundation for future human exploration and habitation of the planet. With further research and development, this automated system could revolutionize the way we produce vital resources in extraterrestrial environments.
