Space Tourism?
Cave_Monster wonders: "With the successful return to earth by Gregory Olson, the US businessman who allegedly paid around £11m for his trip, what are people's thoughts on continuing with this trend? It is definately favourable towards generating extra funds for space programs, and with Mr. Olson preferring to be labeled as a 'flight participant' rather than a tourist, it definately begs the question as to how much input can these paying people have in space research? Experiments that he participated in included further investigation into how the human body deals with weightlessness and the possible causes to lower back pain and nausea, yet are these activities simply carried out so as to 'entertain' or is there real scientific purpose behind them? With the next 'tourist' expected to be Japanese businessman Daisuke Enomoto, should paying people have a real scientific background or is money simply enough?"
Space travel is expensive. No space agency has all the money they need to accomplish their goals. We no longer have the public support we had in the 60's so private enterprise is required to help send us further. If the revenue from these tourists helps fund further space missions then it is justified.
Do we make sure anyone who wants to bankroll the first commercial car knows enough about cars' scientific purposes before we deign to allow him to use one?
Of course you should "let" rich people buy access that later funds democratization of the new technology.
