"The launch of the Shenzhou XII manned spacecraft was a complete success!"
On June 17, the whole network was swept away by "God TWELVE",
"Astronaut" is a proud name
Once again, it was highly concerned by netizens.
Today Xiaobian will take you to visit
The astronauts in the hands of the March 8th Red Flag,
2019-2020 Shanghai March 8th Red Flag Bearer Pacesetter
Zhang Yuhua
"My name is Zhang Yuhua, from the Shanghai Space Bureau."
With short and capable hair, he loves to wear overalls printed with the national flag logo, and every time the "Flower Chief" appears, he is always so energetic.
Zhang Yuhua is a member of the Standing Committee of the Science and Technology Commission of Shanghai Space Administration, deputy commander and deputy chief designer of the Chang'e-3 and Chang'e-4 probe systems, deputy commander of the Chang'e-5 probe system, deputy commander of the first Mars exploration engineering probe system, commander-in-chief of the orbiter, and researcher.
Zhang Yuhua said that she was very lucky to enter the aerospace work for more than 30 years, and personally participated in manned spaceflight, lunar exploration, and Mars exploration, which are major national projects that are of great concern to the whole country, and also witnessed and experienced the process of china's aerospace industry gradually becoming stronger.
"Mother Jade Rabbit" and the moon are inextricably linked
"I was born in the Mid-Autumn Festival, and my nickname is Qiu Yue. The WeChat name is Lunar, maybe my fate with the moon has long been predestined. Zhang Yuhua said, "And now seeing the moon again feels different, after all, there are two of my 'children' on it: Jade Rabbit No. 1 and Yutu No. 2." ”
In 2008, the second phase of China's lunar exploration project was officially approved, and the Shanghai Space Administration won five and a half subsystem development tasks in the Chang'e-3 mission of the second phase of the lunar exploration project, namely: the lunar rover mobile subsystem, the structure and mechanism subsystem, the measurement and control numerical transmission system, the power subsystem, the integrated electronic subsystem movement/mechanism control and drive components, and the lander primary power subsystem, which achieved a breakthrough in the lunar exploration project.
With a paper transfer order, Zhang Yuhua shifted from the field of manned spaceflight for 18 years to the unfamiliar lunar exploration project, serving as deputy chief designer and deputy commander-in-chief, and started the lunar exploration journey of Chang'e's team.
"If you don't want to shed the tears of failure, you have to shed more sweat." Zhang Yuhua often told the team this.
Researchers brought volcanic ash from Jilin to simulate lunar soil, and when the lunar rover walked on the volcanic ash, the entire test site was filled with dust, which would cause irritation if inhaled into the body or stuck to the skin. In order to avoid raising dust, even in the summer, the air conditioner cannot be turned on in the test site, and the indoor temperature reaches more than 40 degrees Celsius. She and the testers wore masks, raincoats and rain boots, and sweated profusely to do the experiment. If it is not enough to prescribe the right medicine, will there be other unknown risks and hidden dangers? The team invited experts from all sides to evaluate, and whenever there was any doubt, they had to answer clearly with data.
Under the situation of parallel multi-model of major special projects, Zhang Yuhua led the research and development team to successfully launch the Chang'e-3 and Chang'e-4 probes through coordinated resources and scientific organization and implementation. On December 15, 2013, Yutu-1 successfully realized China's first inspection and survey work on the lunar surface. On January 3, 2019, Yutu-2 successfully landed in the von Carmen impact crater in the Aitken Basin on the south pole on the far side of the moon, realizing the separation of the two devices, and Yutu-2 achieved the first soft landing and patrol exploration of the far side of the moon.
Today, Yutu-2 has already completed the set task of the 11-month day work period and continues to bravely move forward on the barren moon. Spanning 380,000 kilometers, whenever you see the moon, "Jade Rabbit Mother" Zhang Yuhua will have a special feeling.
Run fearlessly on the road to tackling the key
Since the establishment of the Chang'e No. 5 project in 2011, Zhang Yuhua has led the team to "start from scratch" and launched a journey of research and development. 2020 is the final year of the lunar exploration project to go back to three steps, seven years of development, three years of storage, Chang'e 5 orbiter is Zhang Yuhua's longest experience on the road to the moon, the most arduous development of a spacecraft.
The most remarkable of the third phase of the lunar exploration project was the first rendezvous and docking in the lunar orbit 380,000 kilometers away, transferring the sample container containing the lunar soil from the ascent to the returner. In order to ensure that "grasp, hold tightly, and turn steadily", accurate and reliable control of arresting and transfer agencies is the key to docking tasks. When the orbiter and the ascender meet the initial conditions for rendezvous and docking in the orbit around the moon, the controller is required to control the arrest mechanism to complete the arrest within 1 second after receiving the arrest command, and realize the rigid connection of the two devices within 12 seconds. Is it a blink of an eye to complete the capture, or is it on the moon 380,000 kilometers away? It sounds incredible, but it's the team's mission.
Zhang Yuhua led the young team members to extensively investigate the design of domestic and foreign docking institutions, and in the first two and a half years of sample development, iteratively designed 3 sets of drawings, successfully broke through a series of key technology and development problems, and finally, the live camera of capturing and transferring the moon soil in space was seen by the world. Looking back at the days of "not giving up day and night", how many dark and heavy nights I have seen, and how many gradually bright morning lights have been greeted.
Over the years, she has led the development team to adhere to the multi-dimensional thinking of the task and multi-level combing. The state control is done strictly and strictly, the flight control plan is done cautiously, and the risk control is done carefully and carefully, which has been rooted in everyone's heart; the operation test is done safely and reliably, and the quality work is comprehensive and solid, which is already everyone's standard.
"Ten years of grinding a sword, frost blade has not been tried." Ten years of accumulation and hard work have enabled Chang'e to show a soaring heroism and usher in a feat of sound. Zhang Yuhua led this fresh force with great potential to spell out a new world in the field of deep space exploration of the Shanghai Space Administration. Breakthroughs have been made in key technologies such as the first unmanned rendezvous docking of the lunar orbiter and a series of super difficult actions such as the first sample transfer.
Explorers of "running fire" and "manned"
"Whether it's manned spaceflight, lunar exploration or Mars exploration, I've never doubted the significance of my work. I don't think humans can stay on earth, and in 100 years humanity can go a long way, but life is too short and I can only do a little. ”
While undertaking the organization of the lunar exploration model task, Zhang Yuhua also undertook the post of administrative person in charge of the research and development in the field of deep space exploration, and was responsible for the development and organization of the Mars exploration of the Shanghai Space Agency. After the establishment of China's first Mars exploration project in 2016, she was appointed as the deputy commander-in-chief and orbiter commander of China's first Mars exploration project. As an expert of the national demonstration team in the two fields, he has played an important role in the demonstration and approval of the follow-up lunar exploration mission and the deep space exploration mission.
Previously, Zhang Yuhua also engaged in manned space engineering for 18 years, and as a main member, she participated in the demonstration of The Measurement and Control Communication Subsystem of China's Manned Space Engineering. After The launch of China's manned space project was launched to the implementation, Zhang Yuhua participated in the development of the manned spacecraft power subsystem as the main personnel. As the administrative person in charge of the manned space project of the unit, she led the team to successfully complete the test and launch mission of the Shenzhou No. 1 to Shenzhou No. 7 spacecraft ranges, won the second prize of national defense science and technology progress, and contributed to the realization of the Chinese millennium dream of flying.
From the earth to the moon to Mars, Zhang Yuhua's space road has gone farther and farther, and this is also the epitome of the vigorous development of Shanghai Aerospace and even the entire Chinese aerospace industry in the past two decades, and it is also the epitome of thousands of astronauts who have gone forward and fought hard for the motherland to be strong and the national rejuvenation.
Vast stars,
The future can be expected,
Women in Space,
Please continue to take the "flower" road in space~
