Space travel bets on a dream. To design and build a spacecraft for space travel, you need to be able to figure out how big to make it, how heavy it can be, how fast it will have to go, how much fuel it needs and so forth. For that, you need a theory of how objects move in space and how to make the calculations. Over a period of nearly three centuries (from 1600 to 1900), three brilliant men - Johannes Kepler, Isaac Newton and Konstantin Tsiolkovsky, who said "the Earth is the cradle of mankind - one cannot remain in the cradle forever", worked out almost all the theories of space flight.

By 1951 space travel plans had become more grandiose. Famed rocket scientist Wernher von Braun predicted that a successful Mars mission could be accomplished with as few as 46 rockets in a round trip that would take three years. In a later interview with TIME, von Braun affirmed, "Man belongs wherever he wants to go - and he'll do plenty well when he gets there."

The space age began in 1957 when the Soviet Union launched Sputnik 1, the world's first man-made satellite. Also in 1957, Sputnik 2 was launched carrying Laika, a dog that was the first animal to orbit the Earth. In 1961, Yuri Gagarin became the first person to pilot a spacecraft. In 1963, the United States and the Soviet Union started a race to see who could put a man on the Moon first. In March of 1965, Alexei Leonov of the Soviet Union left his spacecraft to become the first person to walk in space. On July 20, 1969, the United States won when Neil Armstrong and Buzz Aldrin landed on the Moon's surface. The two superpowers have also put space stations into orbit around the Earth. These space structures serve as both a home and a laboratory for space travelers. The United States created and launched the first reusable manned spacecraft, the Space Shuttle, in 1981.

The space The earth moves round the sun, and the moon moves round the earth. When our part of the earth turns to the sun, it is day. When our part of the earth turns away from the sun, it is night. The sun is bigger than the moon. But sometimes the moon looks bigger than the sun, because it is much nearer to the earth. The sun is very bright. It gives very strong light. The moon looks quite bright, too, but it doesn’ t give any light at all. The light from the moon comes from the sun. The moon looks much bigger and brighter than the other stars. But in fact many stars are much bigger and brighter than the moon. They look smaller than the moon because they are farther away from the earth.

If you look at the title “Space Travel”, you must think that I am talking about real space travel. But here I am really telling you about a very good show that you shouldn’t miss, “the Space Travel Theme Park”. Yesterday was a rainy day and my mother and I went to the Space Travel Theme Park in Haidian Exhibition Hall. The Entrance Hall is very big. I looked upwards and saw a blue ceiling dotted with stars. I was starting to feel that I was traveling in space! Suddenly, a statue of an ancient caught my eyes. Its eyes fixed unblinkingly on the far sky. He is Wan Hu, the man who was regarded by the whole world as ” the first man who wanted to fly up to the space”. There is a story behind his stare. When he was looking up to the blue sky, a dream created in his mind－ If I could fly into the sky… I watched Wan Hu for a long time, how important the dream is! I believe most of today’s accomplishments started as a dream, perhaps a silly dream. How I admire Wan Hu! “Come on, dear! Three scientists are waiting for you!” my mum called. I hurried over. “I know them, they are Newton, K·E·Tsiolkovsky and Verne·Jules.” I said eagerly. “Yes, they had made lot of great researches for the space science.” Suddenly, an idea came into my mind －a dream is not enough. A scientific method is very important, too! Then, a big model of a space shuttle came into view. It is the well-known Columbia. My mother and I climbed into the space shuttle quickly. There were so many keys here and there. I was so amazed and enchanted at the sight. What a complex space shuttle! And then, my attention was caught at once by the portraits hang on the wall. The people in the portraits were seven famous astronauts! They all dedicated their dear lives to Columbia space flight. I realized that if a person only has a dream and scientific method, it is still not enough. They must have outstanding courage and selfless devotion. “It is really valuable and really interesting.” My mother said to me when we left the hall. I nodded whole-heartedly. The rain continued heavily. The show of space travel is more than an adventure. I have really learned how a dream comes true－have a dream, love science, and then be dedicated to it! I will remember this for all my life.
