I disagree, you can’t make Mars an afterthought. It requires international cooperation to go there. And it’s not an either or type of deal anyway. NASA can focus in multiple things at once. Hell, we have an entire center at NASA dedicated to Earth observing satellites that monitor the health of the Earths ecosystems. I know bcz I work there. Trust me, we do care about the Earth, and we are trying to fix it. It ain’t the scientists and engineers at NASA that are trying to ignore the health of our planet.
