AI Robot chemist could make oxygen on Mars

A robotic chemist powered by artificial intelligence (AI) can make oxygen from water using only materials found on Mars’s surface. The refrigerator-sized machine separated and analysed ore from Martian meteorites, and then found an effective oxygen-generating catalyst among the more than three million possible compounds — all without human intervention. A similar robot could be sent to Mars to remove the need for astronauts to carry oxygen, or the materials to generate it, from Earth.
