"I and Space Science and Technology" essay activity, write an article (1000 words or more) around the theme of "Exploring Heaven and Flying Ideal"

The memory of space flight comes from an American disaster film Apollo 13. In my mind, space flight = moon = universe, and Armstrong's footprints on the moon. As for parents' occupation, when I was a child, I only knew that they were making "secrets", which seemed to be related to war, far less novel and mysterious than "space shuttle" and "spaceship". When I finally became an astronaut, I realized that the scope of "aerospace" was very large, and the development and production of solid rocket engines were also included.

1965, after graduating from college, my father gave up Beijing's "retention" and resolutely packed his bags and went to Hohhot, Inner Mongolia, known as the city. In fact, what really stops them is the suburb, where the Xia Hong Chemical Plant, which carries their space dream, is located. This used to be an almost uninhabited wilderness. Xia Hong entrepreneurs from all corners of the country with 49 1 East, West, North and South accents, with a firm belief in developing three-dimensional space, have made great achievements in the desert wasteland. They built their own factories, moved their own equipment, dug their own earth, made their own bricks, and built a "famous" building-"dry paving". Regardless of the north and south tastes, they can only see potatoes, cabbage and wowotou on the dining table all year round. The conditions are difficult, but I have never heard my parents or other uncles and aunts complain more than half. Their faces are always full of excitement, leaving early and returning late, and they are not tired at all. My parents love reading books and reading all kinds of books. When I was a child, I always wanted to find one or two "good-looking" books. I couldn't finish reading books on chemistry, physics, propellants and quality management. In the conversation between parents, you can occasionally hear "success", "still developing" and "try again tomorrow". Whenever there is a rumbling sound at the top of the experimental station, my father always stands at the window and quietly counts 1, 2, 3 ... The last number is always written on his face with joy or sorrow. Later, I learned that it was the engine doing the ground test. In my memory, my parents are always "super" healthy and very dedicated. No matter how bad the weather is, they won't be late or leave early. Every year, apart from visiting their families in Beijing, they never ask for leave, or even take recuperation leave. Until I went to work, my father once scolded me for getting off work early. In fact, he only said one sentence: "Everyone ran home as early as you, and the factory was ok." Parents directly and profoundly embody the word "dedication", which is the most basic quality of an astronaut's quality and moral cultivation. Now, after his retirement, his father accepted the anti-employment, and he is still fighting for the aerospace industry he loves. I know that he can't bear to part with more than 40 years of aerospace love, and he can't keep his concern for the cause of solid motors.

In that hard day, the materials for production and life were extremely scarce, but people's spirit was very substantial and rich. They helped each other, encouraged each other, talked and laughed, and the space dream supported them to despise difficulties and be fearless. They are young and brave. They overcame all kinds of unimaginable difficulties in their work and life, and finally made the first solid fuel rocket engine shine in their hands, igniting the hope of China's space industry. There are many, many space warriors who are as conscientious and hard-working as their parents. At that time, a female worker left her child at home when she went to work, and found the child crawling in the pigsty when she got off work at night ... even now, I can't help but feel sad. For parents, the space industry is more like everyone's "child". Under their careful care, the "children" grew up step by step, and every little mistake touched everyone's heart. I remember many years ago, a very important engine ground test, the only time, nearly 200 people in the factory spontaneously went to the scene to watch. It was raining lightly, and people just stood on the top of the mountain, waiting anxiously on the road. With an unexpected loud noise, the test failed, and their faces were not too disappointed, but full of anxiety and pain. A man of iron bones is not afraid of difficulties and hardships, but he is fearless after repeated test runs. That's because their love and loyalty to the space industry have been integrated into their lives.

I was not born when the first artificial earth satellite was sent into space. I can't feel the excitement and fanaticism when the music of Dongfanghong starts, and I have never thought of the connection between space and satellites. Twenty years later, I became an ordinary aerospace employee and also worked in Xia Hong Chemical Plant. As soon as I joined the work, I was so disappointed and confused about this desolate "space city" beyond the Great Wall that I made selfless dedication to my parents' choice to give up Beijing and come here. It took more than 40 years to find out. Young I have my own dreams and dreams. I once asked my parents: Don't you regret it? They just told me: "people have to pursue when they are alive." Watching the factory develop from brick to brick to today is definitely a spiritual enjoyment. I don't care about what I want to regret. "

When I entered the factory, I was assigned to the test bench, and I was busy repeating the same work all day. I use a constant formula to calculate all kinds of data all day, and I don't know what the change of these data means. My work is monotonous, and I have never realized the glory and sacredness of the space industry. Later, after transferring to the propaganda post, I began to have a further understanding of the factory and solid engine business. In 2005, an accidental opportunity gave me a new understanding of my solid engine business. On that day, the leader gave me an arduous task-to introduce the products to the leaders of the Beijing Military Region who are coming to visit the factory. I was blindsided when I saw the long product details sent by the leader. How can there be so many? When I arrived at the workshop where the products were displayed, I saw more than 30 engines, large and small, waiting for inspection, more than half of which I had never seen before. There are no problems with more than a dozen models being produced. What about the remaining dozen engines? In desperation, I remembered that I should ask my parents for help. They accompanied every step of the factory development and witnessed the growth of every engine. When an old master took out his notebook that he had used for more than 30 years, my eyes widened in surprise. The notebook is clearly filled with every model, every product and every bit of these products developed and produced by Xia Hong Factory since 1965 was established. Listen, they told me the story of the development, production and decommissioning of each engine in detail, and told me the brilliant achievements of those engines: the first one, the largest one, the farthest one, and even a model used to solve the political crisis ... Dongfanghong music can resound through the land of China, EPKM can send satellites into the geosynchronous transfer orbit of 36,000 kilometers, the first recoverable satellite can be successfully recovered, and one arrow and two stars can be successfully launched. The people of Xia Hong have indeed made contributions. No wonder their eyes are always shining with pride. No wonder they want to dedicate all their youth and energy to the factory and the aerospace industry they love. No wonder this wasteland silently left their youth and even their lives.

Now the production level of solid-state motors in the factory is not what it used to be. With the increasing intensity of technological transformation, there are tall and beautiful factories everywhere, and the old factories have already been renovated. Large and small production lines constantly create new equipment, and the production capacity has been ten times higher than that of my father at that time. Some models that make our parents proud have completed their historical mission, and the new models replaced by them have faster speed, longer range and stronger performance. More and more cutting-edge technologies, more and more cutting-edge topics, and more and more young college students joining the space team all indicate that the space industry has entered an era of rapid development. The space industry has endowed two generations of astronauts with different responsibilities and missions. To say that their parents' space career is the first and zero breakthrough, a national honor and a historical mission, then the new generation of astronauts is more about the political mission of safeguarding national peace, enhancing comprehensive national strength and realizing the reunification of the motherland.

On April 4, 2006, the roar of bulldozers came from the north mountain of the factory, and the 40-year "explosion" factory collapsed. This is the place where the space hero Wang Lin died, and the largest solid propellant mixing workshop in China will be built here. Fifty years later, the older generation of astronauts left their beloved space career one after another and passed on the space spirit to the new generation. The new and old generations of astronauts have different understandings of the space industry. Old workers are conscientious, down-to-earth, step by step, and the aerospace spirit accumulated over the years is vividly reflected in them. Young astronauts pay more attention to innovation and change, and pay more attention to becoming stronger and bigger, thus reaching a high level.

With the support of space spirit, the inheritance of space culture, the pioneering and innovative efforts of a new generation of astronauts and the progress of the times, two generations of astronauts will finally realize their space dream-to make China's space industry stride forward in the world.
