It’s so ridiculous. We can do that at home. There’s literally no point in living in Mars. No air no gravity, no radiation protection. Even if we make the air here radioactive and the water poisonous, at least there’s air and water.
We need that terraforming exercise to eventually leave the solar system though. Stars don’t live indefinitely. But we probably have to grow up first and try in a couple of centuries.
It’s not like this makes up for everything else, but there is gravity on Mars
I love space exploration for science, but living in Mars makes no sense, sorry. Even in the solar system there’s better places to settle. Heck, even venus is better.
