you'd be surprised to know that it does not cost a whole lot because of elon musk and the research being done at space X, i to am starting my own space based company, im going to be the first to start a business on mars. the actual cost of sending 100 people is only about 6 million dollars, thats just for the fuel, everything else is likely to be around 300 million. Nasa cost are like billions just to send 5 people who would probably wind up stranded, trust me its more affordable than most people think. fallow me for more updates relating to private space industry.
