Out Of Thin Air: NASA Rover Makes Oxygen From Martian Atmosphere

95% CO2? Not possible according to global warming doctrine, the planet would be molten rock.

That’s why they moved it so far from the sun. Erf next.

no fungi.

You would know ...

The bad news about Mars is that it’s eight months away if you use a minimum-energy flight plan.

—
Conversely we had built the 1958 Orion, it would have take 3 weeks, but then, we would have done that by 1965 and have gone to Saturn by 1970. By now, the return flight of the colony ship from A Centauri system would be nearing Earth.

I was never great at chemistry and also long out of school, but the equation must be balanced.

For creating CO2 from CO and O2, to get a balanced equation requires:

2CO + O2 → 2CO2

I must just presume you can also go the other way. I am guessing some energy has to be expended to force that.

Oxygen is not stable in a free form state, and will naturally convert to O2. The conversion by MOXIE on the rover produces C+CO+O2 in a high heat reaction.

Mars at one time had more atmosphere, but lacked the liquid oceans and magnetosphere of earth, so most of it was stripped away. Earth is a very special case where the environment was perfect for complex life.

On the surface your observations fit, BUT 'when I went down into Mars to stay ...' Mars has lots of wter and it is more eaily separated for O₂ and H, and many chemicals are preserved below the surface, away from the winds and cold.

Something is causing out gassing on Mars ...

There is an old Arthur C. Clarke novel - The Sands of Mars - where the problem of oxygen on Mars is solved by lighting one of the moons off as a second sun to get plants to grow.
