　　Man has been traveling into space for more than forty years. Even though today, very few people get the chance to be an astronaut, about thirty per year. This is mainly because of the expense. It costs millions of yuan to train and send astronauts into space. Very few countries can afford this.

　　This why American businessman Dennis Tito paid 20000000 US dollars to the Russian space agency to go into space. He visited the International Space Station. His trip making him the first ever space tourist, took eight days in total. He spent most of his time taking photos, looking at earth and listening to music on his once-in-a-lifetime trip.

　　After landing safely back on earth, Mr Tito thought the trip was worth the money. The only difficulty he had was walking but this is normal for anyone who's been in zero gravity.

　　Some people especially in the American space agency, argue that you must be professional to go into space. They worried about the safety of other astronauts. However, Mr Tito received training before he left. He also helped to prepare food for the others while in space. They told him what to do and where he was allowed to go.

　　A survey carried out soon after Tito landed showed that seventy-five percent of American supported space tourism. Some people are bored of all the places on the earth. They are looking for a new adventure and space is the place.

　　The money Mr Tito gave the Russians paid for twenty percent of their annual budget. If we want to see men on Mars and other planets, we may need rich people like Mr Tito to help us pay for it. The Russians have more rich people who want to become space tourists. They should take them.
