CCTV News(News Connection): Secretary General Xi Jinping pointed out in his reply to the old scientist who participated in the mission of “Dongfanghong No. 1”, “We must follow the example of the previous generation of astronauts, vigorously promote the spirit of” two bombs and a star, “and dare to overcome all difficulties and obstacles., Be brave to climb the pinnacle of aerospace science and technology, let the Chinese explore space more steadily and further away, and make the big dream of building a space power as soon as possible. ” Looking back on the half-century space journey, the vast majority of space workers are excited and proud. They all said they must take into account the trust of the secretary-general, inherit the spirit and fulfill the mission, and move boldly to fulfill the great dream of building a powerful space nation as soon as possible.
Hu Qi, 85, is a leading developer of China’s “Dongfanghong-1” satellite, and has embarked on the development of multiple satellite models in China. For 50 years, it has witnessed the growth of China’s aerospace industry.
“Outraged and hardworking” is the youthful memory of Hu Qizheng and the previous generation of astronauts. In those days when there was no computer, they used the abacus to calculate “Dongfanghong No. 1” little by little.
This notebook more than 50 years ago records the birth process of the “Dongfanghong No. 1” thermal control system. Half a century later, the handwriting above is still clear and orderly, and it also takes us back to that extraordinary time.
At 21:35 on April 24, 1970, the satellite “Dongfanghong-1” was successfully launched. Fifteen minutes later, I received the “Dongfanghong” music broadcast via satellite, and the sound was clear and magnificent. When other countries launched their first satellite, at most only the voice of the “Tick Tick” telegram code was transmitted, but the previous generation of Chinese astronauts used a ballpoint pen and an abacus to allow the first Chinese satellite to sing in the universe . The song “Dongfanghong” rang out. It is also from this point on that China’s space flight has embarked on a half-century space journey.
Self-sufficiency and independent innovation. Along the road opened by Dongfanghong-1, several generations of astronauts have made unremitting efforts and have achieved historic achievements that have attracted worldwide attention.
On October 15, 2003, the manned spacecraft “Shenzhou V” successfully sent astronauts into space, realizing the age-old dream of the Chinese entering space;
On October 24, 2007, “Chang’e-1” was successfully launched, and the pace of China’s lunar exploration began in silence;
On October 17, 2016, the “Shenzhou 11” spacecraft successfully launched, and the two astronauts remained in orbit for more than 30 days;
On December 8, 2018, “Chang’e 4” was released, and China became the first country to perform landing detection on the back of the moon.
In the past 50 years, China has independently developed 17 types of Long March series launch vehicles, successfully deployed more than 300 launches, and sent more than 500 spacecraft into space.
Fight against the change of stars, 50 years of wind and rain. This year, the “Long March 5” will come out again to carry out the first Mars exploration mission in China “Tianwen 1”; This year, the global network of Beidou satellite navigation system is about to be built, and China’s Beidou will serve the world; The lunar samples belonging to the Chinese will be recovered, and the lunar exploration project will move to a new stage. China Aerospace will sing “Dongfanghong”, which is even stronger.
