     What will the future be like? It's possible that we may often fly up into space! Out of all the coolest

inventions of the year, Time chose Spaceship One as the best.

      Spaceship One is a 6-meter-long white spaceship. On June 21,American pilot Mike Melville flew it to

space and back-about 100 kilometers up into the sky. (1) Some might say it's not a big deal. You know, people

went to the moon years ago.

     Well, Spaceship One is special because (2) it is the first spaceship that wasn't made by the government. It

was built and launched (发射) by a private US company. Lots of people want to travel in space. But it's too

expensive. American millionaire Dennis Tito paid almost US $ 20 million to become the first space tourist to

visit the International Station in 2001. So private companies began to think of making their own spaceship to

take other tourists up into space.

    (3)飞船一号的成功是一个好的开端. In the next 10 to 15 years, if you pay $20,000 to $100,000, you

could fly high above the earth.

    What about having your own spaceship in your garage and taking in to space at the weekend?
