Holy Christ you guys are soft as fuck pessimists. Don't you remember what it was like to believe in man as a heroic achiever of seemingly impossible obstacles? I need some HFY mentality. Yes I completely understand that this is death for 99.99% of humanity, but come on. You're telling me that there is literally zero chance for any group of people to make it with even a century of prep time.

Thought about this, but forgot to include it in the OP. I agree, but at least on Earth we have access to the vast stores of fossil fuels that can keep us warm, and Earth is for sure gonna keep a warm core for a billion years. I'm not sure Mars even has an active core.
t.b.h. I'd take my chances on Exo-Earth.
