Make your reservations now. The space tourism industry is officially open for business, and tickets are going for a mere $20 million for a one-week stay in space. Despite reluctance from National Air and Space Administration (NASA) , Russia made American businessman Dennis Tito the world’’s first space tourist. Tito flew into space aboard a Russian Soyuz rocket that arrived at the International Space Station (ISS) on April 30, 2001. The second space tourist, South African businessman Mark Shuttleworth, took off aboard the Russian Soyuz on April 25,2002, also bound for the ISS.
