Theoretically possible? Moving water to Mars
It's probably theoretically possible, but definitely practically impossible. Still, I was wondering about the possibility of moving water from Earth to Mars. With ice caps irreversibly (and probably unpreventably) melting, we'll have 'too much' water in our oceans. Meanwhile, terraforming Mars is a common trope in sci-fi. I wish I could do the maths but I'm a social scientist for a reason...
If we were to combat rising sea levels by moving water away from Earth, how much water would have to be moved? Presuming attainable space-faring innovation, how many rockets would we need, and how much fuel would that burn? Suppose we achieve the impossible and move that much water to Mars, is it likely it'll even stick around, instead of draining or evaporating?
