After the Space X launch I was sort of wondering as to what could be earned by these companies going to space. Now there is the scientific and exploration component and the government will fund that by payment to these companies much like a defense contractor. And there is the satellite component to launch satellites for communication, gps and for spying. But is there a viable tourism component, space mining for minerals, etc.? It was pretty exciting to see the Dragon launch but was sort of thinking about where the money is to be made.
