Nasa Starts Converting Carbon Dioxide to Oxygen on Mars

NASA’s Perseverance rover just notched another first on Mars, one that may help pave the way for astronauts to explore the Red Planet someday.

After successfully demonstrating a controlled (heavier than atmosphere) flight on Mars last Monday, NASA achieved another major stride on Wednesday whereby generating oxygen from Mars’ atmosphere which is rich with Carbon Dioxide gas.

The oxygen was produced by a toaster-sized unit installed in NASA’s Perseverance rover called MOXIE – Mars Oxygen In-Situ Resource Utilization Experiment, the six-wheeled robot’s one of seven devices.

The rover successfully used its MOXIE instrument to generate oxygen from the thin, carbon dioxide-dominated Martian atmosphere for the first time, demonstrating technology that could both help astronauts breathe and help propel the rockets that get them back home to Earth.

The Martian atmosphere comprises 96% carbon dioxide, and the instrument works by separating oxygen atoms from carbon dioxide (CO2) molecules, expelling carbon monoxide (CO) and O2.

The conversion process generates a considerable amount of heat (approx. 800 degrees Celsius) There’s a special shielding installed inside the Perseverance Rover for protection against heat.

“This is a critical first step at converting carbon dioxide to oxygen on Mars,” Jim Reuter, associate administrator of NASA’s Space Technology Mission Directorate, said in a statement.

“MOXIE has more work to do, but the results from this technology demonstration are full of promise as we move toward our goal of one day seeing humans on Mars.”
