But the article references a study showing there is CO2 in lunar regolith, even though that wasn't the source of the CO2 used in this experiment. So, not too inaccurate for a news article. It's extremely unclear how abundant the CO2 is in regolith, or if that finding has ever been duplicated. I don't recall seeing NASA finding that in the many kilograms of regolith brought back by Apollo. Perhaps it's fairly deep and needed an impact blast to bring it to the surface. Hopefully not too deep to be accessible by some kind of strip mining.

If Starship is successful it will bring back lunar soils by the ton, so real progress can be made on this.
