In the past ten years, I have an agreement with China Aerospace
Editor's note
Chang'e embraces the moon, Zhu Rong explores fire, Xihe Zuri, Beidou guides the way... The sky is high and the earth is wide, feeling the infinity of the universe.
We applaud the new record of 183 days in orbit for the "space trip trio"; applaud for the world's first soft landing on the back of the moon by Chang'e-4; applaud for the Zhurong Mars rover's vigorous inspection and survey; applaud for the Beidou-3 global satellite navigation The system is fully completed and the service is proud...
The good news of China's aerospace industry is frequently reported, the Chinese people are excited, and the world is amazed.
However, capturing the moon in nine days and picking up stars in space is by no means a one-day effort.
Behind the world-renowned aerospace "miracle", it is inseparable from the Chinese astronauts who have worked hard and worked hard for generations.
"The heart is beyond the sky and the eyes are far away" is the truest portrayal of their hearts.
What do they think and feel when they ascend to the sky again and again?
April 24, China Space Day, in this festival that belongs to them, let us listen to the strong voice of the astronauts in the new era.
In the past ten years, I have an agreement with China Aerospace
Jing Haipeng, a special astronaut of the Chinese People's Liberation Army Astronaut Brigade
Today is the seventh "China Space Day".
This reminds me of my country's first space day in 2016, all comrades in manned space missions, facing the bright five-star red flag, relived the oath we made when we joined the astronaut brigade in 1998: "I am willing to serve the motherland's manned spaceflight cause. Struggle for life!" This is our commitment to the flag and our lifelong oath.
Since the 18th National Congress of the Communist Party of China, President Xi Jinping has led us on a new journey to build a strong aerospace country. He has high hopes and great trust in the aerospace industry, and he has given cordial care to all astronauts: I will never forget that President Xi went to the Northwest Desert to help us go on an expedition. We will never forget that President Xi talked to us in person, which made us feel infinite strength; we will never forget the cordial reception of President Xi, who encouraged us to keep moving forward, climb the peaks bravely, and make new and greater contributions.
In the past ten years, the Chinese have marched victoriously and toured the sky again and again, making the pace of exploration of space bigger and farther and farther, demonstrating the vitality of socialism with Chinese characteristics in the new era and witnessing the development of our country from The sonorous steps of Da Xiangqiang.
I grew from a rural child to an astronaut, realizing one dream after another. This is the result of the education and training of the party and the people, and the motherland supported me to fly into space.
I often think that as an astronaut, no matter how many times you fly, no matter how high or far you fly, your gratitude will never change, and your original mission will never change.
I remember one time when three of our Shenzhou 7 flight crew visited Hong Kong and communicated with thousands of students in a stadium, a primary school student asked me: Uncle, aren't you afraid of death?
I said: Uncle, like everyone else, is an ordinary person, also of flesh and blood, and also afraid of death.
But there are many things in this world that are worth our lives, such as our astronaut career and manned spaceflight career.
So, I am not afraid of death.
Looking up at the starry sky, the sacred mission of exploring the vast universe inspires us to work hard; looking forward to the future, the magnificent picture of building a aerospace power is calling us to continue to write glory.
The dream of aerospace has a long way to go, and every astronaut is doing his best to run his own club.
We must train our skills, stay young forever, be ready at all times, let the party choose, go to space again, be pioneers again, and win battles again, let the vast space witness, a Communist Party member, a revolutionary soldier, and a Chinese aerospace company in the new era Soldiers' absolute loyalty to the party and the people!
How much fame and fortune can not exchange for this pride
Sun Wu, chief engineer of microwave radar at the meeting of 25 institutes of the Second Academy of Aerospace Science and Industry
On November 3, 2011, I stood in the charge hall for the first time and watched the "Shenzhou No. 8" and "Tiangong No. 1" successfully realize the first unmanned automatic rendezvous and docking in my country.
In space, the microwave radar developed by my team and I showed outstanding performance and successfully completed the mission goal of "first capture, stable tracking, and precise measurement", which excited all the researchers present.
I will never forget that moment, the joy of witnessing my dream become a reality, a sense of pride and mission that no amount of fame and fortune can replace.
With the development of the aerospace industry, I have the honor to participate in many major engineering tasks such as manned spaceflight projects, lunar exploration projects, and Mars exploration missions. The radar products we developed have also been upgraded for three generations, and have experienced ten space missions. , achieved a proud record of ten victories.
Recalling the development process of microwave radar, all successful achievements are inseparable from the pooled resources and joint efforts of the 25 teams of the Second Academy of Aerospace Science and Industry Group. Just like every milestone achievement of China Aerospace, it is the advantage of the new national system to overcome difficulties. results.
In recent years, a great feeling is that more and more aspiring young people have devoted themselves to the aerospace industry of the motherland.
I also bring many young people every year. They have ideals and responsibilities, and hope to use their knowledge and skills on the battlefield that the country needs. They have dreams and work hard, step by step, stick after stick, struggling Run and continue to struggle to achieve dreams.
Good times catch up with great times
Yang Yanbo, deputy commander of manned spacecraft mission at Beijing Aerospace Flight Control Center
I am very fortunate that in the best ten years of my youth, I have caught up with the great era of the rapid development of the aerospace industry in the motherland; even more fortunate, I have personally experienced my country's manned spaceflight, lunar exploration projects and deep space exploration on the front line of flight control tasks. Great feat.
Over the years, as an organization and commander in the front line of mission flight control, from one mission a year to six major missions a year in parallel, I can deeply feel that China Aerospace is moving fast along the planned direction, and I can really feel With the great mission and responsibility, we can truly appreciate the ever-increasing pressure of mission execution, which has aroused everyone's determination to challenge the impossible.
Faced with the new situation, we earnestly study and analyze the characteristics of tasks, innovate and improve the task organization and implementation model, adjust and optimize the allocation of personnel, and constantly break through the upper limit of task execution capabilities.
The comprehensive improvement of flight control technology capabilities, from the improvement of orbit calculation accuracy from 100 meters to 10 meters, from manual arrangement of multi-objective collaborative planning to mature automated planning technology, from manual monitoring of thousands of parameters to intelligent auxiliary analysis of massive information, I I will never forget to discuss the plan, joint debugging and testing with my colleagues, and the countless sleepless nights spent together. Everyone worked together, fought together, and had fun together.
Sometimes, I was hesitant, the task would never be completed, why should I suffer?
But when you see the meticulous, rigorous and meticulous work attitude of the "old comrades" around you, face the full support of family and friends, and think about the lifelong vision of the older generation of astronauts, why do you have to catch up with such a good era? Hesitate!
From "myna" to "Beijing understands", everyone's attention and expectations for the aerospace industry have injected infinite power into us, and also made us feel the mission is like a mountain.
Gather for a common dream
Gu Zhenfeng, Deputy Director of the Test and Launch Department of Jiuquan Satellite Launch Center
"Why are you here? Do you regret it?" This is a question often asked by technicians from prosperous cities to small towns in the Gobi.
I think we are here for a common dream - the spaceflight dream.
In October 2003, the Shenzhou-5 manned spacecraft was successfully launched from the Jiuquan Satellite Launch Center, planting the seeds of spaceflight dreams in my heart.
In 2005, when deciding where to go after graduation, I chose to work at the Jiuquan Satellite Launch Center without hesitation. I also received support from the center's leaders for my continued study of direct Ph.D.
After my Ph.D., I went back to the center again.
Coming to this land that carries the glory and dream of national rejuvenation, I resolutely applied for a position at the front line of the launch and at the forefront.
On April 26, 2013, the Gaofen-1 satellite was lifted off from the launch site. This was my first official mission.
I am very proud of being able to lift a rocket into the sky.
This year, the Shenzhou 10 manned flight mission was in full swing at the center, and I undertook the testing of 20 single rocket control systems.
When the rocket took off, the spacecraft successfully entered orbit, and the astronauts successfully entered space, I deeply felt the sanctity and greatness of the aerospace industry.
In 2015, a new type of solid rocket will be launched at the center. Several young comrades and I were appointed as the system commander. We carefully prepared, organized and implemented carefully, and finally achieved the successful first flight of the new type of rocket.
The new launch team was formed, and I was appointed as the person in charge, leading the team to achieve the first victory in the first battle, consecutive victories, and cultivated a group of key talents.
At present, my country has entered the space station era. As the only manned space launch site in China, the functions and missions of the center are expanding, and other types of tasks are also advancing in an orderly manner, and the prospects are very broad.
With a more progressive attitude, I will contribute my own strength in the journey of building a powerful aerospace country!
The Big Dipper, the star shines around the world
Xie Jun, Deputy Chief Designer of Beidou Satellite Navigation System Engineering
In the past ten years, the Beidou system has completed a huge leap from regional networking to global coverage, from serving the Asia-Pacific region to benefiting the world.
As a Beidou person, I feel very happy.
When the 18th National Congress of the Communist Party of China was held, the 16th Beidou-2 navigation satellite had just been successfully launched. This was the final battle of the Beidou regional navigation system.
On December 27, 2012, the Beidou-2 system officially provided regional services to the Asia-Pacific region, marking another big step forward in the process of establishing an autonomous and controllable satellite navigation system in my country.
We are well aware that this step is just a new starting point for the journey of struggle. The next task of developing and building a global satellite navigation system is more difficult, challenging and burdensome, but we will achieve "China's Beidou, the world's Beidou, first-class" The determination and goals of the "Beidou" have not changed, and the pace of independent innovation and overcoming difficulties has not stopped.
With our mission in mind and shouldering our responsibilities, we carry forward the spirit of "two bombs and one satellite", push forward various tasks down-to-earth, and bravely climb the peak of aerospace science and technology.
On November 5, 2017, the first batch of Beidou-3 network satellites was successfully launched into orbit in the form of "one arrow and two stars".
After that, we continued to work hard for 1,000 days, successfully launched 30 networked satellites, and finally ushered in the "highlight moment" on July 31, 2020 - the official opening of the Beidou-3 global satellite navigation system!
The Beidou spirit of the new era of "independent innovation, openness and integration, unity of heart, and pursuit of excellence" is put forward.
Beidou is "Made in China", "easy to use in the sky and good for use on the ground." Our efforts have made this vision a reality.
The progress of China's Beidou is a microcosm of the leapfrog development of the aerospace industry in the new era - generations of people have continued to struggle, and hundreds of thousands of builders have worked together to renew "China's speed", show "China's precision", and demonstrate "China's speed" again and again. Chinese attitude".
Today, Beidou satellites work safely and stably in orbit, and the system service performance is world-class. The large-scale application of Beidou has entered a critical stage of marketization, industrialization, and internationalization, benefiting not only the Chinese people, but also people around the world; in the future, the application of Beidou will be Bring more to us, to humanity.
There is a "mountain" behind us
Ge Yuanchun, chief designer of the gamma altitude control device of the 35th Institute of Aerospace Science and Industry
On April 16, the Shenzhou 13 manned spacecraft returned to the Dongfeng landing site. The gamma altitude control device developed by the 35th Institute of the Third Academy of Aerospace Science and Technology of China accurately sent the reverse thruster at a height of about 1 meter above the ground. Ignition control command, the return capsule landed safely.
As the project leader of this key stand-alone equipment, I have been involved in the development of the project since 2010, and now it has gone through 12 years.
In 2013, after 3 years of overall work, I took over the responsibility of the project leader from Wang Zheng, the former chief designer.
As the last rod for the safe recovery of the Shenzhou spacecraft, I am well aware of the mission I shoulder.
The two sentences that Wang Zheng said to me the most were, "The country gives us this minute, we must complete the task well", "If you want to enter the launch site without trembling, then work hard in peacetime", These two words have always urged me to never be complacent and never let up.
The Shenzhou 11 mission is the first time I have formally calibrated the final performance status of the product. Although I am familiar with the technical principles and circuit details of the product, although I have gone through hundreds of simulation exercises, as the project leader Presided over the development and production of the entire process, but when I actually adjusted the watch, the pressure in my heart was still enormous.
This performance index is directly related to the final ignition performance, the success or failure of the mission and the safety of astronauts' lives.
Before this, all flight product debugging was done by Wang Zheng himself.
When the watch was adjusted that day, Wang Zheng was by my side the whole time.
Seeing my nervousness, he would tell me a few jokes to relax me. "There is definitely no problem with the redundancy of product design. You can adjust it with confidence and optimize the performance, just like you usually practice." "It's a process you have to go through."
The whole debugging process went very smoothly, he looked calm, but I knew he was keeping an eye on the data.
This is a microcosm of China's aerospace tradition of "passing, helping, and leading". The reason why the aerospace industry can flourish is because there is a "mountain" behind us. It is our aerospace predecessors who are willing to help us grow. The belief that "success does not have to be mine, success must have me".
Hold key core technologies in your hands
Liu Zheng, Chief Technician of Capital Aerospace Machinery Co., Ltd., First Academy of Aerospace Science and Technology
On the eve of graduation, the chief engineer of the Capital Machinery Company, a subsidiary of the First Academy of Aerospace Science and Technology Group, came to his alma mater, Tsinghua University, to give a lecture and exchange.
This is my first contact and understanding of aerospace.
I learned about China's aerospace industry from the seniors' mouths, and when I went to visit and study and saw rows of advanced CNC machine tools, I decided that this is where my ambitions will be realized in the future.
In 2005, when I first arrived at the workshop, when I first came into contact with various large-scale CNC machining equipment, I did not understand many processes, many softwares were not used, and many systems were very unfamiliar... This stimulated my enthusiasm for learning. An opportunity to "recharge", follow the production at the production site, humbly ask experienced craftsmen and operators for advice, and verify the learning results in practice.
In this way, I have grown up slowly, and my colleagues and I have successively solved many national key model quality, efficiency and process problems.
For the development of the Long March 5 carrier rocket, the manned spaceflight project, the Beidou navigation project, the lunar exploration project and other national key tasks have proposed a variety of structural solutions to solve design problems and promote the development process.
Especially in the past 10 years, after growing into a team leader, he led the team to optimize the process of key components of the hydrogen-oxygen engine, and the processing efficiency was increased by more than 9 times.
However, we are well aware that there is still a gap between China's manufacturing and the world's first-class, and there are many shortcomings in equipment, materials and craftsmanship that we need to catch up and surpass.
These cutting-edge technologies cannot be bought or obtained. We must insist on self-reliance and independent innovation, hold key core technologies in our hands, and promote the Chinese people to explore space more steadily and further, and contribute to the realization of the space dream.
