Pop-shots into space like "Spaceship One" might be feasible, but lunar flights? No.
That takes considerable force, which means considerable fuel or considerable technology, both of which are of considerable expense.
Charles Miller, chief executive officer of CSI, said in an interview after the conference that the company was looking at the commercial potential of such a mission. “Would someone be willing to pay for a premier space adventure—first an initial week-long stay at ISS, and then a week-long trip around the Moon like Apollo 8 or 10?” he asked. “Would another nation be willing to pay for the second seat, and send their first citizen ever around the Moon? What are the advertising possibilities? These are very interesting questions. We might be able to do this without a dime of NASA money.”
