Over the course of approximately one Earth year, this system would produce oxygen at a rate of at least 2 kilograms per hour (4.4 lb/h) [1] in support of a human mission sometime in the 2030s. [17] [18] The stored oxygen could be used for life support, but the primary need is for an oxidizer for a Mars ascent vehicle.
Atomic oxygen is produced by photolysis of CO 2 in the upper atmosphere and can escape the atmosphere via dissociative recombination or ion pickup. In early 2016, Stratospheric Observatory for Infrared Astronomy (SOFIA) detected atomic oxygen in the atmosphere of Mars, which has not been found since the Viking and Mariner mission in the 1970s.

The instrument — called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) — has been making oxygen from Mars’s carbon dioxide-rich atmosphere since last year, according to the ...
The system would then look for oxygen given off as metabolic byproduct and report results to a Mars-orbiting relay satellite. [71] [74] If this experiment works on Mars, they will propose to build several large and sealed structures called biodomes, to produce and harvest oxygen for a future human mission to Mars life support systems.
It is hoped that at full capacity, the system should generate enough oxygen to sustain humans once they arrive on Mars. Lunchbox-sized instrument generates oxygen on Mars Skip to main content
One of the many pesky barriers to humans freely exploring and inhabiting Mars is the planet’s lack of oxygen. Luckily, NASA’s Perseverance rover can help. Using an instrument dubbed MOXIE ...
The discovery supports the notion that ancient Mars may have been hospitable for life. [99] [100] [101] It is suspected that all nitrate on Mars is a relic, with no modern contribution. [102] Nitrate abundance ranges from non-detection to 681 ± 304 mg/kg in the samples examined until late 2017. [102]
