Terraforming

I meant in the Earth/Moon system, and was simply pointing out that we didn't have to colonize Mars before having people taking pleasure trips there, was the point of my previous post.

I also agree that this type of thing is quite a ways into the future, as we don't understand enough of how to counteract low/no gravity effects on the human body (and low gravity has only recently begun testing).

I seem to be having a serious problem with communicating clearly, heh. Probably too scatter-brained posting at work...
