NASA's Perseverance rover has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen.

"This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate administrator for NASA.

According to AFP, the technology demonstration took place on April 20, and NASA hopes future versions of the used experimental instrument could pave the way for future human Martian explorations.

Not only can the process produce oxygen for future astronauts to breathe, but it could make hauling vast amounts of oxygen over from Earth to use as rocket propellant for the return journey unnecessary. The instrument, dubbed MOXIE (short for Mars Oxygen In-Situ Resource Utilization Experiment), is a golden box the size of a car battery, and is located inside the front right side of the rover.

It uses electricity and chemistry to split carbon dioxide molecules, to produce oxygen and carbon monoxide. In its first run, MOXIE produced 5 grams of oxygen, equivalent to about 10 minutes of breathable oxygen for an astronaut carrying
