She was so happy that she was so happy that she was so happy that she was telling her dream of spaceflight
The starry sky is immense, and the exploration is endless. We must keep in mind the original intention and mission of serving the country in space, take independence and innovation as the first driving force for development, and accelerate the construction of a space power.
Sun Zhenlian
Model Supervisor of Long March 5 Series Rocket Launch Support System
"The latitude of Yichun is very high, the night in the middle of winter is very long, and the sky is full of stars illuminating the way home from school. Looking up at the starry sky, children will wonder what the universe will have? I dream of finding the answer one day."
At the closing ceremony of the 23rd China Association for Science and Technology Annual Conference, starting with a poetic story, Sun Zhenlian, who is long-haired, gentle and beautiful, described her aerospace dream emotionally.
She is the model supervisor of the Long March 5 series rocket launch support system, and she is the "lady sister" who once moved the entire network and "cried while smiling".
Growing up with the young rocket
When I was a child, I wanted to explore the universe, and when I was young, I heard that "NATO headed by the United States outrageously attacked the Chinese Embassy in Yugoslavia with missiles from different angles." The news made Sun Zhenlian silently firm, "We want to rise for China like Premier Zhou did. "Conviction, and then chose the ground weapon maneuver engineering major.
"I am fortunate to catch up with the era of space acceleration. I joined the Long March 5 launch vehicle model team in 2012 full of enthusiasm. Our goal is to build the most advanced launch site and develop the most advanced launch vehicle. "Now remembering, Sun Zhenlian is still excited.
At that time, in a small village called Xinzhuang in Longlou Town, Wenchang City, Hainan Province, where the road had not been repaired, she and her companions broke through the high-flow liquid hydrogen and liquid oxygen refueling technology and built the largest rocket refueling system in China; With the active launch platform breaking through the overall design technology under the multi-disciplinary highly integrated complex environment, the high-precision theoretical prediction technology of gas flow, and the key technology of large-flow water spray cooling and noise reduction, it is the first time to realize the integration and integration of the whole process of China’s carrier rockets. The research and development level of the launch vehicle active launch platform has achieved a leap-forward development.
"It was a hard time and a time for absorbing energy. Our batches of young people are accelerating their growth, and they are also accelerating the growth of the youngest rocket and young launch site." Sun Zhenlian sighed.
On November 3, 2016, Sun Zhenlian remembered this day deeply.
On the same day, she took her 42-day-old child to the Hainan Wenchang launch site and witnessed the successful first flight of the Long March 5.
"The strong roar of the big rocket makes the earth tremble. The whole world has heard the surging footsteps of the Chinese dream. With new models and new starting points, we are ready to take over the baton of the Long March Rocket family." Sun Zhenlian said.
Withstand the heavy pressure and escort Changwu successfully went around
However, the darkest moment came soon.
On July 2, 2017, the launch mission of the Changwuyao Er rocket failed.
"That night we came back from the test hall and went straight to the meeting room. The cafeteria prepared us an overtime meal, and more than 300 people couldn't eat it." Sun Zhenlian said, recalling the night of success in 2016, how happy the success is , Failure is so desolate.
"During that time, everyone was under great pressure. Mars exploration, lunar exploration, manned spaceflight, and some major missions were waiting for us. They all have a window period, and you have to hit it at that time to save fuel. Take Mars exploration as an example. , If you miss it once, you have to wait 26 months." She recalled.
"I remember Li Dong, the chief designer of the Long March 5 series of rockets, wrote a phrase at that time: How can I look back and say Broken Sword, tearful, broken heart, Jiang Dong elders, guilty and speechless." Sun Zhenlian said with tears in his eyes, "We Without the time and energy to grieve, I can only work hard day and night."
The strong are not without tears, but with tears leading the way.
After 908 days of desperate astronauts, on December 27, 2019, the Long March 5 rocket went around successfully.
That was the day, in the command hall, the rocket successfully went around, and Sun Zhenlian cried with joy.
Her expression at that moment was inadvertently swept by the TV camera. "Miss Sister" who "cried while laughing" was swiping the screen all over the Internet.
"The development of China's aerospace is not only from victory to victory, but also from setbacks. I think this is an arrangement for China's aerospace." Sun Zhenlian said boldly.
Overcoming the difficulties caused by the new crown pneumonia epidemic, relying on bowls of mung bean soup to persevere in the hot weather in Hainan...Finally, the Long Five lived up to expectations and sent Tianwen No. 1 into the sky, flying to new heights and new heights. Accuracy.
On November 24, 2020, the Chang 5 rocket successfully launched again, sending the Chang'e 5 into the scheduled orbit.
Today, Sun Zhenlian proudly brings her children to the National Museum, enjoying the "local products" brought back from the moon, and telling her mother's story to the children.
Recalling the upward curve of the rocket, she remembered the space dream behind the story.
"I wonder how lucky I am. In just 30 years, my personal destiny has changed so much. I grew up from a remote mountainous child to an aerospace worker. Today I have the opportunity to stand here and tell everyone about my dream of spaceflight. The dream of aerospace is no longer a simple slogan. It belongs not only to news reports, but to our tens of thousands of ordinary people." Sun Zhenlian said excitedly.
"In just 30 years, the rapid development curve of China's aerospace has continued to extend upward with the successful launch of one spacecraft and one new rocket. Among them are the shining'Chang'e' Tianwen' and several coordinate points of the space station. Extraordinarily eye-catching. The starry sky is vast, and the exploration is endless. We must keep in mind the original intention and mission of serving the country in space, take independence and innovation as the first driving force for development, and accelerate the construction of a space power." Sun Zhenlian said.
