Write a composition on Hubble's journey to explore the universe.

1.600 words or so of space science exploration composition need to be explored, which means that people explore and study unknown terrain and inaccessible places. When exploring, there will be some unimaginable environmental factors. These problems can't be thought of and predicted before exploration, and of course there will be no reference methods and solutions. Explorers must have a strong and unyielding will, the courage to overcome difficulties and the spirit of no regrets. Those who dare to explore are people who are ambitious and indomitable. They know that from the unknown to the known, they need to explore this process. People who dare not explore are those who have no ambition or are content with the status quo. They even think that exploration is a risky and stupid practice. In fact, exploration is a desire for knowledge, a spirit of struggle and an innovative idea. Since the beginning of Pangu, mankind has never stopped. Seeing that people in the tribe were suffering from lack of food, he risked his life to taste all kinds of herbs. I don't know how many mountains he climbed and how many roads he walked. Later, he even found that people learned agricultural farming with plant seeds and melon seeds, which solved people's survival problems. Dayu learned from the experience and lessons of his predecessors and tried to explore new water control methods. In order to control water, he left home for thirteen years. After more than ten years of hard work, the raging flood was finally subdued. Amundsen spent three years reaching the North Pole through the Northwest Passage and discovered the North Magnetic Pole. After nearly two months of hard work, he became the first person to reach the South Pole. Gagarin, with firm belief and adventurous spirit, took the 4.75-ton "Oriental" spacecraft into space. Yang Liwei became the first person in the world to go into space and see the whole picture of the earth from space. After more than five years of training, he has completed the training tasks of dozens of subjects in eight categories, such as basic theory, space environment adaptability and professional technology, and passed the comprehensive assessment of astronauts' professional technology with excellent results. June 65438+June 654381October+May 2003, heroes went out to conquer space and walked with Shenzhou. There are countless examples of explorers at all times and at home and abroad ... Einstein, Edison, Madame Curie, Qian Xuesen and so on. They all explored in unknown scientific fields until their death. We can imagine that if people have been content with the status quo, will everything around us still happen today? This is undeniable. Mankind is rich and strong because of exploration, and life is beautiful because of exploration. It is important to have the spirit of being brave in exploration. The world needs exploration, life needs exploration, development needs exploration, and only exploration can create innovation.

Today, I will travel in space with Uncle Yang Liwei and Uncle Fei on Shenzhou VII! Put on a spacesuit in the morning and board Shenzhou VII with the attention of thousands of people.

I don't need to mention how excited I am, because I am the first female astronaut to go into space since ancient times. At about half past nine, we set off.

Shenzhou VII is all right, and we are sending information to the staff. The feeling of weightlessness in space is really wonderful, and there is a feeling that cannot be expressed in words.

This time we will live in space for a week. The staff said, we want to walk in space! It's time for lunch. I quickly took out the space food and ate it. Ah, it's still hot, which shows how much the staff care about our lives and specially designed a heater for us.

We have lived in space for four days, and today we will carry out the plan of spacewalking. Uncle Fei Longjun took my hand and carefully walked out of the door of the tracking warehouse.

"Ah, I see the moon!" I couldn't help screaming with excitement. My uncle whispered to me, "Shh! It needs to be quiet here! " So I quickly closed my mouth and carefully observed the moon in space.

There are only potholes on the moon, like footprints. How interesting! I quickly took pictures of everything in front of me with my camera. I have seen the earth. Compared with the vast universe, it is so small, just like a boat.

She is so beautiful, dense forests, yellow deserts and vast oceans. I can't help being attracted by her.

I also sighed from the bottom of my heart: "Space is wonderful!" When the time came, I reluctantly returned to the cabin and sent the photos I had just taken to people all over the world. Just when I was proud to be in space, Uncle Yang Liwei suddenly said, "No, the system is out of order!" " "I was so anxious that I suddenly vaguely heard a voice:" Get up! " "Well, it turned out that I just had a dream, but fortunately it was very close.

Although this is only a dream, I have made up my mind to realize it in the near future and go to the wonderful space world.

My trip to space I dream of going to space one day. Imagine me wearing a spacesuit? Flying in space by spaceship? Explore the mysteries of the universe? Enjoy this dreamlike and beautiful scenery. Huh? How charming is this? I didn't expect my wish to come true magically on this day. NASA invited me to visit this magical and dreamy space. Can I approach space like this? I almost jumped for joy. The spaceship took us to this deep space? A beautiful blue planet floating in interstellar space? This is our beautiful home-the earth. Is it like a blue gem? It looks particularly bright in a dark space. From the spaceship? Is there a red line embedded in the white of the earth in the Himalayas? Which is red and which is green in the Syrian desert? That is the Jordan River, like a flash of green lightning. Enjoy these colorful scenes? I have a new understanding of the earth. Next thing I know, I'm like a little fish? Enjoy the freedom brought by weightlessness in the space capsule. Just when I accidentally put an eye mask on the tourists? A light suddenly appeared in front of my eyes. I panicked and lost my balance? Fortunately, my brain is fast? A carp, yue longmen, saved the day. And then I calmed down? Try to find the origin of this phenomenon in your brain. Huh? How could I forget such an important thing? This is the flash phenomenon. It's caused by cosmic rays colliding with retina. Is this because of the speed of light propagation of human eyes? Slower than in a cosmic vacuum? When cosmic rays enter the human eye, it will cause the speed of light to suddenly increase? Thereby causing the illusion of flashing. The "alarm" is lifted? Everything is back to normal. I fixed myself for a while? I took a nap in the air with my arm on my pillow. Do you know what I look like when I wake up? My face is as round as the moon on August 15th. It is the so-called "lunar phenomenon". I'm not flustered? Because I just studied in a science magazine the day before yesterday. Is this because of weightlessness? There are two liters of body fluids in human blood flowing from the lower body to the upper body? At this time, too much body fluid poured into the head? It caused swelling in the head. Haha? Looking at me in a different mirror in peacetime? It's really funny. I don't know what thrilling new problems will come next. I'm imagining things, okay? Just a crackling sound? A loud voice flooded into my ears? It turned out that mom said, "If you don't get up, you'll be late?" Huh? So I'm dreaming? Although this is just a dream? But it will take me a long time. This wonderful space "dream" has strengthened my dream of becoming an astronaut? Run to the vast space? .

I'm driving a spaceship, looking for alien life in the vast space.

It's been several days since I left the earth. At this moment, I saw a beautiful blue planet through the hanging window.

I drove the spaceship closer, and suddenly I don't know what happened. The spaceship is landing. I checked, and it turned out that the fuel was used up. I panicked. Then, my spaceship turned into a fireball like a meteor and landed on this beautiful blue planet. Well, it's a blessing in disguise. The security system is on. I'm fine.

Besides, when I got off the spaceship, it just burned a little. Just start the high-pressure water gun device. But I didn't expect oxygen on the planet.

I have observed that there are dinosaurs on this planet: some are small and lovely, some are extremely fierce, some are taller than my spaceship of tens of meters, and some have feathers and can fly! Only one of them is the most special. It can stand and command other dinosaurs. Suddenly, several dinosaurs arrested me and took me to see the conductor.

I only heard this special dinosaur say to me, "It's you, it's you who destroyed the environment!" " "I didn't expect dinosaurs to talk. But I have no time to think about it. I immediately said, "No."

"To tell you, we didn't exterminate dinosaurs, but we found a very clever monkey, so we decided to give them the earth. We can all fly, so we found a habitable planet.

Because we have brought instruments to transform the environment, our planet is now the same as the original environment of the earth. We don't welcome you human beings who destroy the environment. "

After I learned the truth, I said to it, "I must invent a green machine to green the environment, eliminate pollution and beautify our planet." He is very happy. I immediately asked him, "Can I have some fuel?" Very happy.

I said goodbye to it and left. Back to the earth, I immediately built one greening machine after another, and our earth will surely become more and more beautiful! Suddenly, I thought of Armstrong's words: this small step is a small step for mankind; This is a huge leap for the whole mankind.

Let's protect the environment of the earth together.

5. My space trip with Marca (1) At night, I lay in a chair outside the house and enjoyed the moon. Suddenly, a gust of wind blew, and I suddenly fainted. I feel as if I was caught by a fairy in green, and flew to the space I longed for to enjoy the beautiful space with her.

When I woke up, I was already in space, floating in space by myself. I'm so happy. Wow! From my side, space is so beautiful, full of flowers and colors.

The bright red cockscomb shows its unique brilliance in the cool breeze, swinging a beautiful big hat, as if to compare with the big cock to see whose crown is more beautiful. Look at the pink roses again, and quietly lower your head, as if you are shy and motionless when you see people.

And those budding buds, who are trying to hold their heads high, as if to take a quick look at this beautiful world? . I was fascinated by the beautiful scenery in space. I feel as if I were in it, swimming among the flowers and enjoying the beauty of the flowers. It was not until the fairy called me for a long time that I came to my senses.

The green fairy said to me, "Let me show you around our space!" " "I said happily," Yes, I like it. " So, she and I walked into the "fairyland on earth" in my eyes.

Wow! Graceful willows, sparkling lakes and green grass are really a quiet and beautiful place. Away from the noise and pollution of the earth, everyone here must feel comfortable, leisurely and quiet! While I was sleeping in this beautiful scenery, the fairy said to me, "It's almost time. I should send you back, or your mother will worry about you. " I must leave this fairytale place.

When the fairy left, she said to me, "You and I are destined to meet again." When I woke up, I had returned to my chair.

When I got home, my mother asked me where I had been. She looked for me for a long time and couldn't find me, but I still refused to say where I went, because this is a secret between me and the fairy, and this secret will be a beautiful memory in my heart. I have been fascinated by the beautiful scenery of space since my last space trip. I hope that the goddess of luck will come to my head again and let me travel in space again and appreciate the beauty of space.

Finally, the opportunity met me again. One day at noon I took a nap in my bed at home.

Suddenly, the fairy in green appeared, and she invited me to visit space again. In a daze, I came to space again.

I took a look, hey, where are those beautiful flowers? Why is it replaced by desert? Into the forest, those once willows are now dead trees, and the crystal clear rivers are now muddy? . I'm not happy anymore. I asked the fairy sadly and doubtfully, "I was not very beautiful when I came here before, but how did it become like this now?" What is this? " The fairy replied sadly: "Because the environmental sanitation of the earth is too poor, and even involves space, the polluted gas emitted by the earth factory suffocates the flowers in space;" The garbage thrown by the earth people makes the willows in space unable to breathe and makes the water in the river turbid? . "

After listening to the fairy's words, I felt very guilty and thought, "I also like littering at ordinary times, which may be the reason why everything here has become so unsightly, and this is also my contribution." Hey, if I had known this, why should I have! " I said guiltily to the fairy, "Sister Fairy, please don't be sad. I will definitely let the original home of space reappear in front of you. "

Sister Fairy looked at me gratefully and said, "Thank you, little friend. Let's work together! " "I was moved to nod. Next, I visited some other places. Just like here, it has been polluted by the earth and turned into a dirty, chaotic and poor place.

After a while, Sister Fairy sent me back to earth. (3) After waking up the next morning, I decided to implement my plan to restore space.

But the whole space is so big, how can I do it alone? So I mobilized all the students in our school to take action with me to protect the environmental sanitation on the earth and in space. In order to educate and remind people not to litter, we first replanted many lawns and trees in space, delivered a batch of pollution-free water to space, and inserted a wooden sign on each green lawn, which read: "The grass is green, please don't hurt it."

After a few months, the environment in space has been obviously improved, the green color has also increased obviously, and the air has been much fresher. One day at noon, Sister Fairy invited me to visit space again. I saw that she was no longer so sad as last time, so I went to space with her in high spirits.

Wow! The space has returned to its original appearance, no, it is more beautiful than the original. The river is clearer, and the grass and willows are back to life.

Sister Fairy said, "Thanks to you and your classmates, space has become so beautiful!" " "I nodded and said," yes, as long as everyone gives a little love, the space will become better.

6. Journey to the Mysterious Planet In the vast universe, there is a mysterious planet. There is no life on that planet, but there are lovely robots and some fighting pets. I think everyone guessed it! He is a sail. Our goal is this small planet. We will take Shenzhou 20 10 to our destination! "Wan Jiayi, are you ready?" Said the captain.

"get ready!" I am confident to answer. "hey!" The rocket flew into the sky with a bang, and soon the spaceship landed. I opened the hatch to meet my new friend! ! Cece, the mechanic, ran out to meet me and said, "Hello, guests from afar!" " "I said excitedly," nice to meet you! "Then, I went to the invention room. Sean waved to me and said, "This is our newly developed Nuo Nuo. It can accompany us like an elf, and it has many unexpected functions ... "After that, I went to Lucio Star, collected a few Hilori minerals, bid farewell to them, and returned to the earth ... It feels good to go home! I handed the ore to the captain, and he praised my good performance in this mission! On the earth, the scene of sailing always appears in my mind from time to time! What a pleasant trip! I like Thayer.

7. Imagination Composition My Space Journey Composition 350 The universe where darkness and beauty coexist is boundless, mysterious and really desirable.

Hundreds of years have passed like running water in a blink of an eye. In this century, I have made full preparations for my space travel. The manned spacecraft 747 is finally completely completed. Standing in front of this tall spaceship, I was really excited to see this superluminal spaceship with joy.

Opening the hatch, I walked into the cockpit and started the spaceship. Under my driving, the spaceship flew towards the vast universe. A beautiful sphere is displayed on the screen. The white and blue stripes are interlaced with each other, which is particularly beautiful. I know this is our home-the earth.

The ftl spacecraft continued to fly, standing in the cabin, and I enjoyed the beautiful scenery outside. The universe under the stars is so mysterious and beautiful. On the way forward, I passed a red planet, which was very charming, so I stopped the spaceship and prepared to land. Pick up the tools, put on the spacesuit and get off the boat. I see this planet is full of grotesque rocks and there are no green plants. What a strange place! I was looking around when suddenly a terrible multi-legged animal came at me. I hurried back to the cockpit of the spaceship, started the spaceship and left quickly. According to the data, this is what people call terrible aliens.

A week in space opened my eyes. With the development of modern science and technology, mankind has now developed space into a tourist resource, and people can visit space anytime and anywhere.

At night, the moon is high and the stars blink at me. I can't stand the temptation of this beautiful space and start a bold fantasy. Where am I? "I think so. There are many machine parts in it. Take a closer look. Oh, I'm sitting on a spaceship. " where am I going? "I said to myself. At this time, the display screen on the spaceship told me: You are in the universe now, and there is planet X under the spaceship. You are going to be a guest there ... After a while, the spaceship landed and I got off the spaceship, feeling a little lighter. I just jumped lightly and came to the park. Suddenly, I am in awe of the beautiful scenery of the park: there are trees, birds, flowers, clear streams and cheerful fish. On earth: trees are cut down, rivers are polluted, and fish can't survive ... the earth is very different from planet X. At this time, I felt a little hungry, so the aliens took us to the restaurant. The food there is everything, which can be deformed, discolored and stale. There is a button next to every seat here. When you press the button, a robot will appear to serve you alone ... After enjoying these delicious dishes, we came to a strange zoo again. There are many kinds of animals here: sheep's heads grow on horses, rabbits' tails are on foxes, peacock's feathers are on crows ... animals here can communicate with humans. It is getting late. I really hate to go home and look back at the beautiful planet X. At this moment, a cool breeze woke me up. It turned out to be a fantasy, but this is.

9. My Space Journey Composition 600 words Do you want to visit space? I am the commander-in-chief of this plan. Let me introduce the whole journey to you.

There are two ways to visit the moon, one is by spaceship, and the other is by space elevator. The two methods have their own advantages and disadvantages, as well as similarities. * * * One of the similarities: everyone has to go through the "space transfer station" before going to the moon; * * * Similarity 2: The travel time is the same, that is, the time from leaving the ground to returning to the ground is the same. Because the speed of the two tools is different, there will be time error, so you must be careful when choosing tools. The speed of the spaceship is very fast, which can let you reach the moon in advance, but you can't see the beautiful scenery along the way, but your time on the moon will increase and the price is much cheaper than taking the space elevator, so more people choose the spaceship. As for the space elevator, it is relatively suitable for people with rich families, because its speed can be changed and you can enjoy the beautiful scenery in the universe all the way. When you get to the moon, you can concentrate on watching the scenery on the moon, which is also beautiful and can make you feel high.

The characteristics of these two tools are described. Finally, the trip to the moon began with exploring a grotesque cave. Everyone will get some tools and use them to cross various terrains. At the finish line, you can't come out early, and you can't walk around. There are many organs in it. You'll see something shiny when you come out. This is your prize. Then I will explore by myself and go wherever I want. Finally set foot on the road home.

I'll stop here. Do you want to travel in space?

Is it okay?
