It’s not looking like colonists will have to bring water or oxygen to Mars either. Mars Direct, from the book, brought oxygen. But that was before we found plenty of evidence of water on Mars.
I agree about Antarctica. I’d also like to see a large robotically tended greenhouse on Mars for a few years. (This has been done on a small scale in Canada’s arctic.) But again I’m talking about a credible colony, not Mars One.
And a mere one-way mission - the astronauts supplied from earth for the rest of their natural lives rather than the more expensive task of bringing them home - need not be self sufficient.
