On Space Day, listen to the voices of the older generation of astronauts

　　On April 24, 1970, the "Long March 1" rocket developed by the First Academy of Aerospace Science and Technology Group successfully launched my country's first artificial earth satellite, opening a new era in China's aerospace industry.

In March 2016, with the approval of the Party Central Committee and the approval of the State Council, April 24 of each year was established as China Space Day.

　　This year is the 100th anniversary of the Communist Party of China and the beginning of the 14th Five-Year Plan.

On the occasion of the sixth China Space Day, let us listen to the aspirations of the older generations of astronauts from the birthplace of China's space industry, the First Academy of Aerospace Engineering, and feel their unswerving aspirations to serve the country and their sense of mission to climb the summit. The ardent expectation for the aerospace industry.

"The general secretary's request made us unable to calm for a long time"

　　In 2020, on the eve of the fifth China Space Day and the 50th anniversary of the successful launch of the Dongfanghong-1 satellite, General Secretary Xi Jinping wrote back to the old scientists involved in the Dongfanghong-1 mission.

As two of the veteran astronauts, Han Houjian and Fang Xinhu talked about this reply with a wave of confidence and emotion: "The general secretary’s entrustment between the lines, especially “to be brave to climb the summit of aerospace science and technology, so that the Chinese people will explore space further. The hope of stabilizing further away keeps our moods from being calm for a long time."

　　Looking back on his aerospace career, Han Houjian said: "In the 1950s, under the leadership of the party, it was not easy for the people of the whole country to tighten their belts and support us in aerospace. We have a strong sense of responsibility in our hearts, and we want to win glory for the country!"

　　Recalling the painful history of his hometown being bombed by the Japanese army when he was a child, Fang Xinhu couldn't help but burst into tears.

Since then, "the country must be strong, weapons are important" has become his simple idea.

Later, "coming to aerospace for the motherland and contributing to the motherland in aerospace" became his true portrayal, and his personal happiness, sorrow, and sorrow are closely linked to the motherland and space.

Today, Fang Xinhu has not changed his original intention, and is still running on the front line, "As long as the spacecraft needs it, I will give it to you."

　　The two veteran astronauts hope that more young people can join the aerospace industry, and hope that they will fully understand the important historical responsibilities, love the party, the country, and the people, and contribute their wisdom and strength to the summit of science and technology, the realization of a space power and the great rejuvenation of the Chinese nation. .

"Success is the silent and selfless contribution of aerospace personnel"

　　Yu Menglun, an expert in ballistics design and an academician of the Chinese Academy of Sciences, has worked hard for the motherland’s aerospace industry for 60 years. From the "Long March 1" to the "Long March 5" and "Long March 7" new-generation carrier rockets, he has almost participated in and Witness the ballistic design of each rocket.

Today, the 85-year-old Yu Menglun has white hair like frost, still fighting on the front line of spaceflight, designing the beautiful arc of the rocket flying into the sky.

　　Generations of astronauts regard career as their life, and continue to struggle with youth, sweat, and hard work.

"Everyone forgets me to work, and there is no minor injury. 11 colleagues left us when they were working. I remember a colleague who said before his death:'I want to do work too much, but unfortunately, I won't be able to do aerospace anymore.' "60 years of aerospace career has made Yu Menglun deeply feel that "success is the silent and selfless contribution of spacemen."

　　As the fifth leader of the "Yu Menglun team" of the General Office of the First Academy of Aerospace Engineering, Yu Menglun believes that the rocket is a multi-disciplinary and multi-system integrated body. The role of the team is very important. Problems in a certain group may affect the ultimate success or failure. "It can be said that the short board determines the height."

"During the '14th Five-Year Plan' period, we will further optimize the ballistic design method, solve the problem of rapid ballistic optimization design, and carry out multi-disciplinary joint design to improve design quality and efficiency."

"The journey is long, only innovation"

　　Liu Zhusheng, an important caster of China's flying "shen arrow" and academician of the Chinese Academy of Sciences, is the chief designer of the manned rocket Long March II F.

Under the leadership of him and the commander-in-chief, the team overcame all difficulties and designed and produced the rocket with the largest takeoff mass, longest length, and most complex system in my country at that time, making my country the third country in the world to independently master manned space technology. .

Over the years, he has "held the helm" of more than ten manned rockets and witnessed their "hundred shots and hits" and successfully sent 11 astronauts into space.

　　"China’s aerospace started from scratch. Decades have passed. Our business has stepped forward to a new level. During the "14th Five-Year Plan" period, my country will implement manned space station projects and other major projects, complete more than ten space station missions, and move forward. Longer-distance deep space exploration. We have more tasks and heavier responsibilities, and we should work hard and pay attention to every detail design in order to achieve greater success." Liu Zhusheng sighed.

　　Looking forward to the future, Liu Zhusheng sent a message to the younger generation: "The journey is long, and only innovation. Young people must pay attention to technological innovation. Innovation is the driving force for development. We must broaden our thinking and vision and achieve greater progress in all majors. "

　　The 65-year development of China's aerospace industry is a process of continuous hard work, collaboration, innovation, and inheritance of generations of aerospace personnel.

"Standing at the intersection of history and facing a new journey, our new era of spaceflights will surely keep in mind the entrustment of the party and the country, never forget the expectations of the predecessors, and take everything for the motherland, everything for spaceflight, and everything for success rooted in their hearts. Let the aerospace industry move into a broader and vast space." said the youth representative of the First Academy of Aerospace Engineering.
