Oxygen-producing materials made from meteorites found on Mars have been produced using a robotic artificial intelligence (AI)-chemist. The research, published in Nature Synthesis, provides a proof-of-concept for generating oxygen and may have implications for future manned missions to Mars.
Potential future manned missions to Mars will require oxygen as it is essential to human activity on the planet, being used in rocket propellants and life-support systems. One of the ways to make these potential missions more cost-effective in the long term and less complex would be to use resources already present on the planet to create oxygen, rather than transport materials from Earth. Recent evidence of water on Mars and analysis of the elemental composition of meteorites found on the planet could provide an opportunity to make catalysts using Martian resources.
Jun Jiang from the University of Science and Technology of China, Hefei, China and others developed a robotic AI-chemist that is able to create catalysts that can be used to produce oxygen from Martian materials without human intervention. “Using a machine-learning model derived from both first-principles data and experimental measurements, this method automatically and rapidly identifies the optimal catalyst formula from more than three million possible compositions,” the authors write.
