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.
I’m on board with ‘living on Mars makes no sense’ at least until we really run out of space here, but we have much more pressing issues before that. But I doubt Venus being more suitable. The high atmospheric temperature of Venus (~460°C) is pretty harsh and it is much more easy to heat than to cool stuff down. The high pressure also makes getting there difficult with the hard entry. Mars at least has a similat rotation period to earth.
