> But there could be parts of Mars we can transform, within a 100 years or so - just like the early settlers of every continent on Earth, ever in the history of mankind - and turn into a habitable place to live.
Mars' atmospheric pressure is 0.6% of Earth's. It's for all practical purposes a vaccum. Liquids boil away. You will die without some kind of suit even if you converted all the gases to nitrogen and oxygen.
Mars has 10% of the mass of Earth. Surface gravity is a third of Earth's. Long-term survival in low-gravity might be possible, but it will not be pleasant and it will mean returning to Earth will be effectively impossible.
Mars will never be habitable unless we assemble a whole new planet.
I can imagine a several large domes to protect people and crops from the atmosphere, but the threat of them being hit by a meteorite seems like a critical issue, unless we also shipped some AA or powerful lasers to combat them.
