The main initiator and founder of "China Sky Eye" - Nan Rendong, this great name, he burned his energy and successfully opened the "Sky Eye", but he turned into a star and accompanied the Sky Eye for a long time!If there were no Nan Rendong, it would be hard to imagine that Tianyan would stand in the world. For more than 20 years, Nan Rendong has been fascinated by this Tianyan, from the site selection, project establishment, guidance of key technology research to model testing, until success, he dedicated the rest of his life to it without reservation!
01 Nan Rendong, the champion of Jilin science.
In February 1945, Nan Rendong was born in Longshan District, Liaoyuan City, Jilin Province. Nan Rendong has been diligent and inquisitive since childhood, and is a "top student", and won the "Learning Xi Pacesetter" award certificate of the whole school when he was in junior high school. In 1963, he was admitted to the Radio Department of Tsinghua University with the title of "Science Champion in Jilin Province", becoming the only young talent admitted to Tsinghua University in Liaoyuan for 10 years.
In 1977, the national college entrance examination enrollment was resumed, and Nan Rendong picked up books and was admitted to the Chinese Academy of Sciences as a graduate student in astronomy. After graduating, he was sent to the Netherlands as a visiting scholar, and was later hired as a visiting professor by the National Astronomical Observatories of Japan, enjoying world-class scientific research conditions and salary. During this period, he participated in the large radio telescope projects in 10 countries, and won praise from the international astronomical community for his many outstanding achievements.
In 1990, when Nan Rendong's fame was boiling, he resolutely gave up the favorable conditions abroad and chose to return to China and became the deputy director of the Beijing Astronomical Observatory of the Chinese Academy of Sciences. At that time, his income in one day abroad was worth a year's salary at home. Many people laughed at him for being stupid, but he said lightly: "In my eyes, knowledge has no borders, and countries must have knowledge!"These short words reflect Nan Rendong's confidence and courage in taking up the burden of China's astronomical cause.
02 Turn ideas into great powers.
In 2006, he was elected President of the Radio Astronomy Division of the International Astronomical Society. In July 2007, the state approved his "radio telescope project", and construction began subsequently. He served as the chief scientist and chief engineer of the FAST project, responsible for the scientific and technological work of the 500-meter aperture spherical radio telescope, and led the team to overcome a number of technical difficulties one after another, ensuring that the FAST project was completed and put into use, making China a world leader in the field of single-aperture radio telescopes.
In 2014, the "Sky Eye" reflector unit is about to be hoisted. Before the official hoisting, the "Little Flyer" manned test should be carried out. In this test, it is necessary to lift the person and send it to the test node disk more than 6 meters high, and then manually operate the test in mid-air without a foothold. Several young workers vied for the first step, but were dissuaded by Nan Rendong, who insisted that he should be the first to go up. Fortunately, there was no danger, Nan Rendong landed safely after completing each process operation, and made a comprehensive explanation of the precautions and operation points summarized by personal experience.
On September 25, 2016, the 500-meter aperture spherical radio telescope (FAST) project was completed and opened in the karst depression in Pingtang County, Guizhou Province, and began to receive electromagnetic waves from the depths of the universe. It took Nan Rendong 23 years to go from prime to twilight, turning a simple idea into a great power, and achieving China's unique project in the world - the 500-meter aperture spherical radio telescope FAST, which is Xi called "China's Sky Eye".
With the help of the "Sky Eye", which can receive electromagnetic signals 13.7 billion light-years away and can reach the edge of the universe, scientists can spy on interstellar interactions, observe dark matter, determine the mass of black holes, and even search for possible extraterrestrial civilizations. At the moment when "Sky Eye" succeeded, Nan Rendong fell. On September 15, 2017, Nan Rendong, a famous astronomer in China, died at the age of 72 due to the sudden deterioration of lung cancer and ineffective rescue.
03 China's "most beautiful struggler".
Mr. Nam is the initiator and founder of the FAST project. Since 1994, he has been responsible for site selection, pre-study, project establishment, feasibility study and preliminary design of FAST. As the chief scientist and chief engineer of the project, he was responsible for compiling the scientific objectives of FAST, comprehensively guiding the construction of FAST project, and presided over a series of technical problems such as cable fatigue and moving optical cable, and made outstanding contributions to the successful completion of FAST project.
In May 2017, during his serious illness, he won the National Innovation Award. In April 2018, it was named one of the "Ten Dead National Backbones". On December 18 of the same year, Nan Rendong was awarded the title of "Reform Pioneer", awarded a medal, and was awarded the main initiator and founder of "China Sky Eye". On September 17, 2019, ** signed a presidential decree to award Nan Rendong the national honorary title of "People's Scientist". On September 25, 2019, he was selected as the "Most Beautiful Struggler".
On October 15, 2018, the National Astronomical Observatories of the Chinese Academy of Sciences announced that an asteroid with an international permanent number would be officially named "Nanrendong Star". Since then, there has been an "Nanrendong Star" in the sky, guarding the "Chinese Sky Eye" and the young generation of Chinese astronomers. Whenever night falls, the brightest star in the sky, "Nanrendong Star", looks away from FAST.
04 Shine in the long river of history.
Today, the world's largest single-aperture radio telescope has opened its "eyes in the sky" to the sky, but those who boiled the green silk into white hair for it have closed their eyes forever. Perhaps, he was just too tired. Perhaps, he just wants to turn into a star and be with the "eye of the sky" for a long time!
In the magnificent process of more than 70 years since the founding of the People's Republic of China, there are always such people, they are unknown, selfless dedication, do not forget the original intention, dedicated to the country, dedicated to the people, do not hesitate to sacrifice their personal family and life, in their hearts to regard the motherland and themselves as a firm whole, it is true that paying is their life's mission.
In peacetime, in order to make the motherland better and put China's astronomical science and technology at the forefront of the world, these scientists gave up their high salaries abroad and chose to return to China, and the interests of the motherland were priceless in his heart. They are the heroes and soldiers of the rising nation and deserve the respect and love of the people of the whole country.
We sincerely hope that overseas patriotic children, people's life is very short, but the inheritance is very long, only the belief left to the motherland, the motherland will not forget, the people will not forget, in the long river of time will shine!
