According to a recent research, a toaster-sized equipment aboard NASA's Perseverance rover is "reliably" converting carbon dioxide into oxygen on Mars at a pace similar to that of a tiny tree on Earth.
Since February 2021, when Perseverance first landed on Mars, the Mars Oxygen In-Situ Resource Utilization Experiment, or "MOXIE," has been producing oxygen from the CO2-rich atmosphere of the Red Planet.
The instrument produced six grammes of oxygen per hour during each of the seven testing runs, or about the same pace as a small tree on Earth.
According to researchers, a scaled-up MOXIE may be transported to Mars before a human trip to create oxygen continually at the rate of several hundred trees.
"In-situ resource utilisation" refers to the collection and use of a planet's materials, such as CO2, to produce oxygen or other resources that would otherwise need to be transported.
The Perseverance rover from NASA is "reliable" producing oxygen on Mars.
The equipment has proven it can reliably and effectively transform Mars' atmosphere into pure oxygen, despite the required compromises in the current design.
According to Professor Hoffman, the atmosphere of Mars is much more changeable than that of Earth.
