NASA’s Mars 2020 rover to produce oxygen on the Red Planet

NASA’s Mars 2020 rover will not only investigate the Red Planet, searching for evidence of past life on Mars, but also it is expected to lay the foundations for future human exploration of the planet. One of the mission’s instruments, called MOXIE, will have a special task – testing technology essential for Mars colonization.

“MOXIE is one of nine instruments, but it is the only one that is relevant to human exploration,” Donald Rapp, one of the co-investigators of MOXIE, told

MOXIE stands for the Mars OXygen In-situ resource utilization Experiment. With a diameter of 9.4 by 9.4 by 12.2 inches (23.9 cm × 23.9 cm × 30.9 cm), the instrument will produce oxygen from the Martian carbon dioxide atmosphere at a rate of about 0.35 ounces (10 grams) per hour. It is a 1:100 scale test model of a future instrument that would be efficient for human explorers on Mars.

“The object is not to produce a lot of oxygen. The object is to show that the process works on Mars. MOXIE produces only about 10 [grams] per hour of oxygen, less than one percent of full scale,” Rapp said.
