And how are we going to deal with the temp's and lack of atmosphere?
As I said, we would deal with that in the next 100-200 years. Possibly sending unmanned robotic expeditions up there. I don't know the solution, but by studying the environments on mars now, we can find plants/bacteria/chemicals/other to kick start the environment. Few prefabs shelters and we might have a stop off base there. BUT, there has to be a benefit to show for all this work. The cost of such an expedition will get cheaper as time goes on and robotics are going to be more than capable of carrying it out.
