At 0:43 on December 30, with a roar from Xichang Satellite Launch Center, the long march 3B carrier rocket was ignited and lifted off, successfully put the communication technology test satellite 9 into the predetermined orbit, and the launch mission was a complete success. ▲ Chang San Yi rocket takes off (photographed by Xiao Guojun) So far, China Aerospace Science and Technology Group Co., Ltd. has successfully concluded its Aerospace Launch mission in 2021. Aerospace Science and Technology Group has handed in an impressive report card to the party and the state with its victory in 48 Aerospace launches throughout the year. 2021 is a milestone year in the history of the party and the country. The Communist Party of China ushered in its centennial birthday and embarked on a new journey towards the second Centennial goal. This year, the aerospace science and Technology Group launched a "super mode" of Aerospace Launch, with an annual launch frequency of "40 +" the highest in history for the first time, with a launch success rate of 100%. Hundreds of spacecraft (including onboard) were sent into space, laying a solid foundation for China to accelerate the construction of an aerospace power. At the same time, China's annual number of aerospace launches reached 55, ranking first in the world. The communication technology test satellite No. 9 launched this time was developed by the Fifth Institute of Aerospace Science and technology group, which is mainly used to carry out the verification of multi band and high-speed satellite communication technology. ▲ Chang San Yi rocket booster transfer (Photo by Xiao Guojun) The long march 3B carrier rocket for this mission was developed by the first Institute of Aerospace Science and technology group. ▲ hoisting of Chang San Yi rocket booster (photographed by Xiao Guojun) 2021 is an extraordinary year. With the steady improvement of the country's comprehensive strength, China's major aerospace projects have received frequent reports of success, and new launch vehicles have appeared one after another. Aerospace Science and Technology Group has stepped into the fast lane of development. In the opening year of the 14th five year plan, it has seized the momentum at its peak and repeatedly created brilliance. On March 12, China's new generation of medium-sized high orbit liquid launch vehicle, long march 7a launch vehicle, successfully launched test satellite 9, marking the addition of new members to China's new generation of medium-sized launch vehicle family. The carrying capacity of chang-7a rocket in geostationary transfer orbit is no less than 7 tons, filling the gap in China's high orbit carrying capacity. On April 29, the long march 5B carrier rocket soared to the sky, accurately putting the first spacecraft and core module of the Chinese space station into the predetermined orbit, and the first battle of the on orbit construction mission of China's manned space engineering space station was won. On May 29 and September 20, the Long March 7 carrier rocket sent Tianzhou 2 and Tianzhou 3 cargo spacecraft into the predetermined orbit respectively. This is not only a key battle for the construction of China's space station, but also a strong base war for China to move from a space power to a space power. On June 17, the long march 2F carrier rocket successfully launched the Shenzhou 12 manned spacecraft carried by Chinese astronauts Nie Haisheng, Liu Boming and Tang Hongbo into space. They entered the Chinese space station as the first "visitors" to the Chinese space station. On October 16, the Shenzhou 13 manned spacecraft carried by Chinese astronauts Zhai Zhigang, Wang Yaping and ye Guangfu was successfully launched into space by the long march 2F carrier rocket. They began a six-month space work and life, and the Chinese space station opened an era of long-term presence. On October 14, the long march-2 D carrier rocket successfully put China's first solar exploration satellite "Xihe" into the predetermined orbit, and China officially entered the "era of exploring Japan". On December 10, the long march 4B carrier rocket successfully launched 05 satellites of Shijian VI, and China's long march series carrier rockets successfully completed the 400th launch.
