NASA and its partners in the International Space Station have agreed in principle to let a 28-year-old South African become the second paying tourist on the orbiting outpost, the U.S. space agency3 said on Tuesday. Internet magnate Mark Shuttleworth signed a contract on Dec. 4 with the Russian Aviation and Space Agency to fly aboard a Soyuz space taxi to the station in April 2002, almost exactly a year after U.S. millionaire Dennis Tito became the first to experience space as a paying guest.
