D
Researchers in China have developed a robotic chemist powered by AI that might be able to obtain oxygen from water on Mars. The robot uses materials found on the red planet to produce catalysts(催化剂) that break down water, releasing oxygen.
“If you think about the challenge of going to Mars, you have to work with local materials,” says Andy Cooper, a chemist at the University of Liverpool. “So I can see the logic behind it. ”
The study was led by Jun Jiang at the University of Science and Technology of China. Jiang and his team used a mobile machine the size of a refrigerator with a robotic arm to analyse five meteorites(陨石) that had come from Mars. The team's goal was to investigate whether the machine could produce useful catalysts from the material.
The AI-powered system used some chemicals to dissolve(溶解) and separate the material, then analysed the resulting substances that consists of two or more elements. These then formed the basis of a search of more than 3.7 million formulae(公式) for a chemical that could break down water—known to exist as ice at Mars' poles and under the planet's surface—a process the team said would have taken a human researcher 2 000 years. The result was a catalyst that could release oxygen from water, with the potential for use on a future Mars mission.
If a catalyst that can produce oxygen from water can be made on Mars, this would remove the need for missions to carry such a catalyst from Earth. Jiang says that for every square metre of Martian material, his group's system could make nearly 60 grams of oxygen per hour, potentially removing the need for astronauts on future missions to the planet to carry oxygen from Earth to use when they get there. “The robot can work continuously for years,” says Jiang.
Jiang points out that his group's robotic chemist could also be used to produce other useful catalysts on Mars, for processes like fertilizing(施肥) plants. “Different chemicals can be made by this robot,” he says. And Mars isn't the only place where it could be used. “Maybe lunar soil is another direction,” Jiang says.
