So, I think it's worth it for people to go to Mars for exploration, and to build a base somewhere up in space or the moon. I think we should figure out how to exploit resources in space: asteroid mining, space-based solar power, etc. Even if it's all woefully unprofitable and inefficient at first. And I think we should figure out how to eventually get another self-sufficient lump of humanity off this rock, but that seems like it could be 150+ years out. But there's no reason, other than the exploration of Mars itself, to go down the gravity well to Mars. > I would love to see all the energy put into space exploration to simply be put in rehabilitating existing land. It's not like these are really the same resources.
