    Even though we knew moon well now, it has many touching legends n ancient times. Chang’e is a beauty who ate the elixir and then flew to the moon, she lived in the “Wide-Cold Palace” (Moon Palce) with a jade rabbit. Wugang always cut down the sweet-scented osmanthus trees on moon as a punishment. Though these legends are not true, we can still store them in our memories.

    Why do we care so much about other planets? The reason is that the Earth is suffering many troubles. These troubles include: global warming, air pollution, water pollution, the population is quickly increasing, soil deterioration and decreasing natural resoures. The environment is not as good as it once was. All the troubles mentioned above are warnings us that we should pay more attention to the environment, and take care of our mother-Earth. Don’t make it suffer any more troubles. The reason is simple, we have only one Earth. Why not cherish it and make it more beautiful.

    Even Mars is the most similar to the Earth in the solar system, scientists have said that outer-space is not fit for human beings to live in at the moment. Because there is not enough of the necessary thing that we need in space. We can’t find the basic thing-water. On other planets, so we should assume the attitude, “looking for a horse while riding a donkey, but not looking for a horse while discarding a donkey.” Only remember that we have one Earth. It is our duty to protect and cherish it.

    In 1990, NASA launched a telescope called “Hubble” to the orbit of Earth. Without the affect of atmosphere, we can see the stars far away about 200 hundred million light-years. It is the farthest area we can see so far in the universe. People learnt a lot with the telescope, and NASA plans to launch a new telescope to space to take the place of “Hubble”. It is more modern. We can see longer distance with it. We hope that one day we can know all the secrets about the universe.

    October 26th, 2003, in China, the “Divin Land 5” was launched to space successfully and after 21 hours it landed safty. It proved that we have the ability to conquer space. Now scientists in China have started a project to explore the moon. Soon detectors have been launched. We hope a good result. The Chinese scientists plant to launch “Divin land 6” to space next year. We hope that day can come soon.

    Now, we have full confidence in ourselves. However, before we explore space, we should take care of our only homeland, Earth. So that we have the right conditions to explore space and have a good result.

    What will human being’s future like? No one knows. Please remember to cherish everything we own now. Don’t be regretful for the past! Looking back at the history, and looking into the future, so we can dominate our destiny.

    Distance lends enchantment to the view! All my friends, let’s make our world more beautiful!
