    September 21st, 2050—At a press conference today, it was announced that the first tourist heading for Mars would be the 38-year-old American businessman Patrick Clifford. He would leave the Earth in the launching window of June, 2052, and he would set his foot on the surface of Mars in November, together with 6 astronauts who would further explore the planet.

    Patrick has a two-year training ahead of him to get ready for the trip. Not only will he spend five months in getting to Mars, but another 600 days there before he can go back home. Patrick was very excited, "This has been my dream since I was four, and seeing the first man on Mars 20 years ago made me realize that it was possible."

    To be able to pay the 1.3 billion dollars for his ticket for the trip, Patrick sold his majority stocks in the company which his father had built. "I know that my father would have been proud of me if he had still been alive today. He knew what this meant to me," says Patrick.

    So, how is he going to spend his 600 days on the red planet? "Well, since I don't have a job, when I get back after selling the company, I have plenty of time to come up with a new business idea," Patrick says and laughs. If he brings a shovel(铲子), he can start building the first hotel there, but maybe he shouldn't expect too many guests until someone can offer a lower transfer fare.
