I do not believe we should be making a single-focus effort to get people on Mars just for a jingoistic headline. If we are serious about colonizing space, it should be a step along the way, and not one of these steps should be taken without making a secure base and refueling station at each point along the way. I wonder if anyone more expert can help me. Please tweet your reactions or any useful links. Diagram
