Should we A) colonise other planets or B) build habitats in the middle of space, like O'Neill Cylinders and stuff? (lemmy.ml)

Terraforming other planets would be astronomically more challenging than fixing our own planet and we don't seem to be able to get our shit together to do that. Even if we are capable of terraforming other planets, it would take many centuries at minimum. O'Neal cylinders are far more likely to work once we start industrializing the moon.

If the colonization strategy is the Moon then Mars, I expect humanity would have the technology needed to colonize Mars easily while terraforming occurs.

The problem with an O'Neil Cylinder is bringing up enough processed material to build one.

The problem with an O’Neil Cylinder is bringing up enough processed material to build one.

One possible solution is a moon base. The moon is full of titanium and iron.

And then you could launch the stuff out of a weaker gravity well with no air resistance.

I don't see the application of an O’Neil Cylinder within the Earth and Mars gravity wells given how expensive they would be to build next to better places to grow crops.

If one does get built, I would expect it in orbit around Jupiter or Saturn to support activity there.
