On April 23, 2020, General Secretary Xi Jinping wrote back to the elder scientists who participated in the Dongfanghong-1 mission, and extended sincere greetings to them. In the letter, Xi said in the new era, workers in the aerospace sector should follow the example set by the elder scientists, and uphold the “spirit oftwo bombs and one satellite”. He encouraged space industry professionals to overcome difficulties and hardships to achieve new heights in space science and technology, and expected them to strive to strengthen and expand our space exploration and make our country a great space power as soon as possible.
In October 1964, with a deafening sound and a mushroom cloud in Lop Nur, China exploded its first atomic bomb. In June 1967, China successfully tested its first hydrogen bomb, becoming the fourth country in the world to master the technology of hydrogen bomb. In April 1970, China’s first man-made satellite was successfully launched, which listed China as the fifth country in the world to develop and launch a man-made satellite on its own. These are miracles created by the vast number of researchers in exploring modern science and technology. The spirit of “two bombs and one satellite” featuring love of the country, selfless dedication, self-reliance, hard work, active coordination and courage to climb has been permanently engraved on the land of China.
The “two bombs and one satellite” project was carried out when China’s material and technological foundation was very weak. Living in the tents on the Gobi, the self-reliant scientists eventually built China’s “Atomic City”. Qian Xuesen was courageous and responsible. He said “what foreigners can do, we Chinese can also do it”; Sun Jiadong said “to engage in ‘two bombs and one satellite’ project, one must be self-reliant. We Chinese cannot be overwhelmed”; Yu Min, known as “the father of China’s hydrogen bomb”, remained anonymous for 28 years to fill the gap in China’s nuclear theory.
China’s “two bombs and one satellite” project is a collective cause. Every success it has achieved is the result of the efforts and creativity of thousands of people. The glory belongs to every unsung hero who works with great effort on this front, to all Chinese people, and to the Chinese nation that never pauses in the pursuit of progress!
