A part of NASA “We asked a NASA professional“Series on YouTube, the space agency has answered the following question:”Is there oxygen on Mars?“
The short answer is “Yes“, but it’s almost not the amount we have here on Earth and it’s definitely not enough for a human being to breathe as he walks on the surface. To put it in perspective of the low oxygen content that Mars’ atmosphere contains, NASA says the amount of oxygen present in Mars ‘atmosphere is 0.13%, compared to 21% of Earth’s atmosphere.What is rich in Mars’ atmosphere is dioxide carbon, which can be useful.
NASA technologists have created a piece of technology called MOXIE, or the Mars in situ oxygen utilization experiment. NASA has equipped Perseverance with a MOXIE and, just a few months ago, the rover was able to do so successfully extract oxygen from the carbon dioxide present in the atmosphere. The amount of oxygen that was extracted was only small, but the experiment showed that the concept works.
When thinking about future human explorations, NASA says it will have to send a MOXIE that is about 200 times the scale of the MOXIE on Perseverance. This large-scale MOXIE would provide oxygen to astronauts living in the colony.
