Antarctica is a great place to do science, and the majority of the activity at the US South Pole base is currently astronomy. Mars and the Moon will pass through that sort of phase before they might become actual colonies.

Yeah, I don't mean to put down Antartica. I think the research we do there is very cool, and we should keep doing what we can there. But it isn't even close to an alternative to humanity pushing further out into space.
