"The impressive performance of Moxy shows that it is possible to extract oxygen from the Martian atmosphere, helping to provide breathable air or rocket fuel to future astronauts," says NASA Deputy Administrator Pam Milroy. The purified Martian air is then compressed, heated and sent through the electrolyzer, as the electrolyzer splits carbon dioxide into carbon monoxide and oxygen ions, and the oxygen atoms are reassembled to form O2.Each round takes a few hours, and in this operating hour, the experiment is designed to produce up to 10 grams, equivalent to approximately 20 minutes of breathable oxygen for one astronaut. In general, and the liquid fuel needed to power the spacecraft, about 500 metric tons of oxygen will be needed, according to a study published in the journal Science Alert."We have to make decisions about what things to validate on Mars, and I think there are many technologies on that list, and I'm very happy that Moxy was the first," Hecht explained.
