it does not state the mars dust contains oxygen only that it can be converted into it
@relentless_eduardo @SMetzeler
The official narrative is or maybe was that you can not change one element into another except by a nuclear reaction
So you would be doing a chemical reaction on something that already has oxygen in it's chemical formula to end up with oxygen in the O2 form without other elements chemically binded to O2
But I also presume Mars is a light in the sky and they do not have real footage of it's surface and the Mars rover images or videos are fake
