Terraforming would require the dissociation of the iron oxide in the rock to extract the oxygen or water to extract the oxygen, but in the case of water, what to do with the hydrogen, perhaps a tall stack to blow it off into the upper atmosphere to escape into space. Problem is insufficient nitrogen to dilute the oxygen so the planet doesn’t become flammable. In any case, the other difficulty would be that the atmosphere would likely escape to space almost as fast as we generate it.
btw, I am an ‘American’ but not a Native American, therefore, a child born on Mars would be a Martian, but, I guess not a Native Martian, which, as far as we’ve seen, is nonexistent.
