  • $\begingroup$ Thanks for the very complete answer. I am a bit chocked to see that we are going to transform Mars' air. What's the point ? Do we really plan to, one day, breathe on Mars' ? $\endgroup$

    $\begingroup$ @Nico Why would you be choked to see a planned technology demonstrator try to extract a couple of deciliters of oxygen out of carbon dioxide? Yes, if we'll send astronauts there, it would be nice if they don't suffocate. It changes nothing for the atmosphere of Mars on a global scale, it already has about 0.15% (1.5 billion tons) of oxygen and 0.06% (557 million tons) of carbon monoxide. I think you're giving way too much credence to human ability to change much anything about one planet's environment with one little rover. $\endgroup$

  • $\begingroup$ Yeah, you're probably right with your last sentence. It just seems weird to me to think about colonizing a new planet... But that's just a matter of opinion ;) $\endgroup$
