On April 20, 2021, an experiment on the NASA Perseverance Mars Rover broke down the CO2 Mars atmosphere to 2CO + O2. That makes it the first instrument to produce Oxygen on another world.

Still a ways to go, design maximum is 10 grams per hour, people need around 60 grams per hour.

Not keen on the 2CO for every O2 through
Yeah, definitely not a long-term solution!
Sorta like what we're doing here on Earth with generating CO2

Why not? Combine it with O2 production from water and you have synthesis gas. That means it is not just the first O2 extraction but also the first step to the production of propellants or even plastics on mars.

Since this is on Mars, first you have to find the water. 😁

You are not up to date. The water already has been found, e.g. by the Phoenix lander:

There is water ice sequestered in the rocks under the surface. The planet bis long dead

Ice water is ok for this?

In principle yes, but it will be a technical challenge to mine it on Mars. Maybe it is possible to drill a hole and to melt or sublimate it underground.

so throw it away!
Yes, what could possibly go wrong?
