For the first time in history, humankind has managed to obtain oxygen from the atmosphere of Mars, which is 96% carbon dioxide. This was achieved by the Perseverance rover, which arrived on the Red Planet in February, thanks to the experimental device MOXIE on it.
After two hours of preparation, MOXIE began producing oxygen on its own at a rate of 6 grams per hour. Eventually, it managed to produce 5.4 grams of oxygen, which could be enough for one person to breathe for 10 minutes. At the same time, the maximum rate of oxygen production by the device can be up to 10 grams per hour.
NASA's associate administrator for STMD Jim Reuter said the experiment was an important first step towards ever seeing humans on Mars. At the same time, according to him, oxygen on Mars is important both for the breathing of people and for obtaining rocket fuel, which will be useful to future researchers in order to return home.
