Rich Americans are willing to spend large sums of money on space tourism, according to a poll released recently. Possibly bored by the ordinary daily life on earth or inspired by the exciting heroic deeds of such pioneers as first American in space Alan Shepard and first millionaire in space Dennis Tito, the poll says 7 percent of rich Americans would pay $ 20 million for a two-week orbital flight and 19 percent would pay $100,000 for a 15-rninute suborbital flight.  The poll by Zogby International was commissioned by Futron Corp. , a Maryland aerospace consulting group which has a $1.8 million contract with NASA to explore the commercial applications of space travel, including what space tourism could look like in the next 20 years. Zoghy International conducted telephone interviews with 450 Americans whose yearly incomes were more than $ 250,000 or whose net worth was more than $1 million. Futron’s NASA project program manager Derek Webber said, "We commissioned this survey in order to get an idea of what rich people think and not the man in the street who loves the idea of going into space but can’t afford it."
