Cheer up, I was being cynical because of this specifically: "We need a new planet so we can try new things, create new ideas, and generally liberate ourselves of traditional conventions." Of all the places to try out 'new conventions', the harshest frontier in human history does not sound like a good idea. And I agree, BioSphere was terrible, but the important thing is that it failed (mainly) for human reasons, not scientific ones. I think it is entirely possible we lack the capacity as a species to thrive outside our world. I don't think the scientific problems are impossible to overcome, but I do think anyone who flies there with any notion of romantic exploration and a new beginning is going on a suicide mission.
