MOXIE completes its last run on Mars, producing oxygen from the atmosphere
The MOXIE instrument on the rover Perseverance in Jezero Crater on Mars has completed its sixteenth and last operational run, once again demonstrating that oxygen can be extracted from the Martian atmosphere in sufficient quantities to supply a future colony of humans.
Since Perseverance landed on Mars in 2021, MOXIE has generated a total of 122 grams of oxygen – about what a small dog breathes in 10 hours. At its most efficient, MOXIE was able to produce 12 grams of oxygen an hour – twice as much as NASA’s original goals for the instrument – at 98% purity or better. On its 16th run, on Aug. 7, the instrument made 9.8 grams of oxygen. MOXIE successfully completed all of its technical requirements and was operated at a variety of conditions throughout a full Mars year, allowing the instrument’s developers to learn a great deal about the technology.
Future MOXIEs will likely be larger in scale, even more efficient, and include methods for liquifying and storing any oxygen produced, though for producing a breathable atmosphere for Martian colonists all that would be needed would be an enclosed habitat. An operating MOXIE-type oxygen generator could fill it.
