Please write a 500-word essay on my ideal, ideal (astronaut)

Students, what is your ideal? Maybe you want to be a people's policeman to protect people's safety; maybe you are a teacher and impart knowledge to more children; or maybe you want to be a doctor who saves lives and heals the wounded so that more people will no longer be afraid. Disease. My ideal is to be an astronaut exploring the universe and explore more mysteries of the universe.

Since China's "Shenzhou 6" and "Shenzhou 7" were successfully launched in 2006 and 2007, I have been filled with infinite yearning for the mysterious universe.

2006 is a year worthy of commemoration by the Chinese people. Uncle Yang Liwei finally became the first Chinese astronaut to go into space after passing many rounds of screening. He has taken China's aerospace technology one step further. After the launch of Shenzhou-7 in 2007, China's aerospace technology took a great step forward. Astronauts Y Zhigang, Liu Boming, and Jing Haipeng successfully stepped into space from the Shenzhou 7 capsule. Although they took a small step, they took a big step. I have seen that China has produced one aerospace hero after another and the great contributions they have made to the motherland’s aerospace technology. I have a cold respect for these space heroes, so I pay more attention to the information about the universe.

I remember one day not long ago, I was watching TV at home. I know that Nanning will see the entire partial solar eclipse. After watching the partial solar eclipse, I checked out a lot of information about the universe. I saw the vastness of the universe and scientists using the soil brought back from the moon to grow large and strong vegetables and fruits. I thought of asking astronauts to cultivate various plants on the moon. Wouldn't it be more convenient? As a result, I strengthened my belief in exploring the universe.

I know that this kind of fantasy will not work. Only by working hard can you realize your ideals. Being an astronaut also requires a strong body and a spirit that can endure hardships. Being an astronaut also requires the patience and firm willpower to never give up. And now I am not thinking about how to achieve these goals. What I am accomplishing is what I should do most now, and that is - study hard. Only by learning knowledge can I realize my ideal. In the future, I will definitely work harder to build a strong body and continue to explore new knowledge. With rich knowledge and a strong body, board the mysterious and vast universe.

As soon as I thought that I represented the 1.3 billion Chinese people, I couldn't suppress my emotions and shed tears of emotion.

After a long "journey", I finally came to the moon! According to the book, the lowest temperature on the moon is 100 degrees Celsius and the highest temperature is minus 170 degrees Celsius. But wearing the clothes carefully developed by the staff, I feel that the temperature is almost the same as the temperature on the earth... "Xiaoxiao, go home and sleep quickly. Don't catch a cold!" "Oh, I understand, mom.

“For the peace and progress of mankind, the Chinese have come to space! "When boarding the "Shenzhou" 5 manned spacecraft, Yang Liwei, the astronaut on China's first manned space flight, wearing a spacesuit, wrote this sentence for reporters with passion.

Chinese Come, Yang Liwei is here! At 9:00 on October 15, 2003, as the 38-year-old lieutenant colonel astronaut Yang Liwei flew into space on a manned spacecraft designed and manufactured by China, the Chinese nation's thousands-year dream of flying finally came true. Indeed, China has become the third major space country to send astronauts into space after Russia and the United States.

The whole world remembers the name of a Chinese--Yang Liwei.

On June 21, 1965, Yang Liwei was born into a scholarly family in Suizhong County, Liaoning Province.

Yang Liwei’s father graduated from college in the early 1960s.

His father first worked as a teacher and then did administrative work in an agricultural and sideline products company in Suizhong County; his mother worked as a Chinese teacher in a middle school in the county until she retired.

He also has one older sister and another. My younger brother, the five members of the family live in harmony and live a peaceful life.

"Work hard and be an honest person", this is what Yang Liwei's parents ask of him.

< p> As a child, Yang Liwei had a smart mind and quick reactions.

When he graduated from elementary school, he was admitted to the top class of the county's key middle school with excellent results and participated in many mathematics competitions for middle school students in the county. , won many awards.

In the summer of 1983, 18-year-old Yang Liwei was admitted to the Eighth Flying Academy of the Chinese People's Liberation Army Air Force.

During his four years in the academy, his His academic and training performance has always been excellent.

In 1987, Yang Liwei graduated from the flight academy and became an attack aircraft pilot in a certain division of the Air Force.

That day, he flew a War Eagle at an ultra-low altitude over Lake Aydin in Turpan.

Suddenly, the plane made a loud noise, and the instrument suddenly showed a sudden increase in cylinder temperature and a sharp drop in engine speed! Yang Liwei understood that he had encountered a serious "in-flight parking" failure, and one of the plane's engines was not working. At this critical moment, Yang Liwei was extremely calm: He must drive the plane back! He held the control stick firmly, slowly closed the throttle, and climbed up and down with only one engine left.

At 500 meters, 1000 meters, and 1500 meters, the plane crossed the Tianshan Mountains and flew towards the airport.

When it was approaching the runway, the remaining engine stopped working.

He decisively took emergency measures to lower the landing gear and successfully landed the fighter plane that had completely lost power. Imagination essay 500 words

My understanding of aerospace is very superficial. I think that flying airplanes and rockets into the sky is aerospace. The actual research in the aerospace field is very extensive and profound. No matter how deep or shallow my understanding of aerospace is, I am very Like aerospace.

I remember when I was a child, my favorite among the toys that adults bought me was airplanes. Now I still have two well-preserved remote control airplane models at home; I still remember when I was in kindergarten, I I made a model rocket with my grandfather and visited the exhibition in the whole kindergarten. When I was in elementary school, I joined an airplane model interest group, and in the group I made six model airplanes.

When the airplane model I made was flying in the sky, I thought of Uncle Yang Liwei. He traveled in space on a manned spacecraft built by our country. This pioneering achievement made China famous in front of the whole world. People strive for light and show their faces.

As my age and knowledge continue to grow, my understanding of aerospace has gradually deepened. At the same time, questions in my mind have come one after another, such as: How can a rocket fly without wings? Will artificial satellites fall from the sky? Another example: Why can manned spacecraft travel into space? ...With these questions, I bought some encyclopedias about "universe, space, and natural science".

Through study, I initially learned that: a rocket is an aircraft that uses an engine to inject high-temperature and high-pressure gas backward to generate and exert force to obtain forward thrust, and thereby move forward. It is generally controlled by a power system and System and structure The system consists of three parts.

Artificial satellites and space probes are unmanned spacecrafts with highly sophisticated automatic control devices. So far, they have conducted close or on-site inspections of the Moon, Venus, Mars, Halley Star, etc. , and achieved fruitful results, so humans call it "the scout of cosmic information."

In addition to sending artificial satellites and detectors to space for inspection, humans also hope to fly into space. Manned spacecraft is one of the tools for humans to travel into space. It generally consists of a cockpit, an orbital module, and a service module. , docking cabin and emergency life-saving device.

The cockpit is the core of the spacecraft. The orbital module is equipped with various experimental instruments, and the service module is the place that provides living support for the astronauts.

The manned spacecraft can carry out space activities independently, can also be used as a "ferry" between the ground and the space station, and can dock with the space station or other spacecraft and fly jointly.

my country's self-developed Tiangong-1 and Shenzhou-8 successfully docked in space for the first time at 1:36 a.m. on November 3. This is more than 40 years after the United States and Russia conducted the first rendezvous and docking test, and China became the world's largest spacecraft. We are the third country in the world to master automatic space rendezvous and docking technology. This shows that our country's aerospace technology has reached the world's top level. I am proud and proud of it. At the same time, I love aerospace even more.

I am a young child and the future of my motherland. I know that there are still many mysteries in the universe waiting for us to explore and discover, and there are still many problems in the aerospace field waiting for us to understand and solve. , Therefore, in order to realize my beautiful ideal of traveling in space and exploring the universe, and to contribute to the aerospace industry that I love when I grow up, from now on I will work hard to learn scientific and cultural knowledge, firmly master the skills, and strive to be an excellent Young Pioneers.

... An essay about the adventures of astronauts in less than 500 words.

"The blue sky, white clouds, and a beautiful condor are flying.

"This is the magical description of astronauts that I saw in the book.

It makes me have endless yearning for the blue sky and white clouds.

Each of us has our own ideals.

Some people’s ideal is to be a general in the future, leading thousands of troops; some people’s ideal is to be a teacher, cultivating countless talents; and some people’s ideal is to be a doctor, who can Save lives; and my ideal is to be an astronaut and be able to travel in space and fly my dreams.

The beautiful space makes me have many reveries.

How did the white clouds change? Why do stars shine? What's on the moon? Can we go up there... In 2005, my country's "Shenzhou 6" manned spacecraft was successfully launched again, traveling into space and successfully returning to Earth.

Nie Haisheng and Uncle Fei Junlong are so proud! They traveled through space and brought honor to their country! This incident has greatly increased the ambition of us Chinese people, and it has also strengthened my confidence: I must be an astronaut, travel to space, and let my beautiful dreams fly.

If I were an astronaut, I would fly into space and stay there to build a space camp belonging to us Chinese so that more Chinese people can see the magic of space.

I am now a primary school student, but I firmly believe that as long as I study hard, I will be able to realize my ideals in the future.

Put on the wings of science and travel in space. I want to be a pilot. Essay 500 words

I really want to be a space pilot! How great it feels to fly a spacecraft in the universe! What a great feeling you get after completing a task! One day I fell asleep...suddenly, I heard "Comrade Yu Dexuan, please get on the aircraft, Comrade Yu Dexuan, please get on the aircraft!" I got on the aircraft and only heard "Five, four, three, two, one, take off."

"Tiangong 1 and Shenzhou 8 are ready to merge!" With an order, Tiangong 1 and Shenzhou 8 began to merge. "Five meters, four meters, three meters, two meters, one meter, The integration was successful!" Two days later, I suddenly found a brief message sent from the earth: separation; Shenzhou 8 returned to the earth.

After the separation was successful, I reluctantly returned to Earth.

"Zhuangzhuang, wake up" "Ding ding ding ding -" Dad and the alarm clock woke me up from my sweet dream, and I got up immediately.

How I want to be a space pilot! An essay of about 400 to 500 words on Science makes life better.

Science makes life better. From ancient times to the present, there have been many great celebrities who have set out towards science: Copernicus risked his life to propose the heliocentric theory, Edison found tungsten filament and invented the electric light through thousands of experiments; from "When three people walk, there must be a teacher from me" to "Scientific development depends on everyone.

" These all revolve around science.

In ancient times, people were always influenced by theism and did not believe in science. They burned incense and worshiped Buddha every day, but in the end they did nothing.

Many people worship and believe in Buddha, and eventually reap the consequences.

But there are many people who believe in science. Although many people are sent to the guillotine, they refuse to give in before death. This spirit is the crystallization of science.

Nowadays, people live a happy life, have a variety of electrical appliances, make full use of various resources, and apply all kinds of knowledge. This is also the crystallization of science.

Once upon a time, I heard such a question: "Do people in ancient times have a better life or do people today have a better life?" I don't know how the person being asked answered, and everyone looks at the question from different angles. It’s strange, but I think there is science to be happy.

A thousand years ago, people's lives were simple and hard-working. They needed to communicate with each other through flying pigeons. From Shanghai to Beijing, it was also a difficult journey across mountains and rivers.

If you suffer from pneumonia, there is no cure and you can only pray for the whole family. For many years, wars have been going on, just to fight for land. It is pitiful and tearful.

People today are fulfilled and happy.

The medical technology developed so far can cure almost all common diseases in life. People whose lifespan has been extended have more time to expand and enjoy life.

The rapid technological development of natural subjects such as biology and chemistry has brought a variety of spiritual food to people who were originally curious.

Human beings affirm their self-worth while exploring and inventing. People also gain happiness while enjoying the benefits brought by technology.

Human beings have such great wisdom and have discovered and created so many "miracles".

The decryption of the double helix of DNA molecules, the Internet benefiting millions of households, the first cosmic speed to send space shuttles into the universe, the development of cloning technology to help disease patients regain their lives, these technologies have never been seen in ancient times. Passed, and this is the symbol of human science.

The reason why science can make life better is because of the efforts of batch after batch of good people who use science and technology rationally.

They apply beautiful technology to the construction of social harmony, the enrichment and shaping of human material and spirituality, the never-ending and correct pursuit of truth and the admiration of high moral quality.

When someone asks you, in what period do you think people were happier, please don’t hesitate to tell them, now.

Because we are living in the cradle of science and enjoying the happiness brought by technology.

We also have reason to believe that the rapid development of science and technology will be 100% used to benefit mankind, nature, and the world, allowing science to bloom in its most beautiful and pure glory! I’ll give you a sample essay for reference. I hope you can write your own essay well. I wish you success in your studies! An essay on how astronauts live in space, 500 words

When astronauts get up in the morning and wash their faces, they wipe their faces with a wet towel soaked in skin care lotion, and then spread it with a sanitary napkin. *** Brush and comb your hair. After combing, your hair is very clean and your head is ***.

As for brushing teeth, American astronauts chew special gummy candies instead, while former Soviet astronauts brush their teeth with wet towels, and the results are very good.

Shaving is easy on the ground, but in weightlessness you must use a special razor. This special electric razor has a special blade designed to absorb beard debris. box so that beard debris will not float in the cabin.

For astronauts who stay in space for a long time, bathing is a big problem. For this reason, scientists have designed a special space bathroom and supporting facilities.

The bathroom is a foldable sealed plastic cloth cover that is folded and placed on the ceiling of the bathroom in the living cabin. There is a barrel-shaped water tank on it, with an electric heater to control the water temperature, a nozzle, and a storage tank. Pipes connected to water tanks.

When astronauts take a shower, they first put on a breathing mask that extends outside the bathroom, and then put down the airtight plastic sleeve to prevent water droplets from splashing outward.

Start the electric heater to heat the water in the water tank, turn on the nozzle, and scrub with a towel soaked in cleaning fluid.

The water vapor in the bathroom flows into the waste water tank below from the many micropores on the floor. When the waste water tank is full, it will automatically alarm and send the waste water to the water treatment system.

How do astronauts relieve themselves during spaceflight? It turns out that there is a bathroom with a zippered rubber curtain in the space capsule. The urinal is vacuum, and the toilet bowl is connected to a plastic sleeve. After defecation, the rubber valve is quickly closed, and the urine falls into the airtight rubber bag and enters the plastic. container.

The garbage and waste in the cabin are loaded into the container. After the container is full, it is ejected into space and burns automatically after entering the atmosphere.

Huh? Why is it so lively in the forest? It turns out that a forest fruit beauty contest is being held now! quick! quick! quick! Without further ado, let’s go take a look! Player No. 1 makes his debut.

Ah, isn’t this my good friend Huohuo! I saw Huo Huo dancing on the stage wearing a flaming skirt.

Oh, it turns out that Huohuo danced to "Ode to Joy". No wonder she was wearing a dress that looked beaming with joy.

Huo Huo jumped up and down, picked up the microphone on the ground, and turned it around in a circle as a finishing move.
