小任班长的博客 my country's largest solid rocket "Li Jian-1" successfully made its maiden flight, sending 6 satellites into predetermined orbits
According to CCTV news, at 12:12 on July 27, 2022, Beijing time, the Lijian-1 carrier rocket (ZK-1A) successfully made its maiden flight at my country's Jiuquan Satellite Launch Center.
According to reports, the Lijian-1 carrier rocket also successfully sent 6 satellites for the space new technology test satellite, the orbital atmospheric density detection test satellite, the low-orbit quantum key distribution test satellite, the electromagnetic assembly test double satellite and the Nanyue Science Star. The orbit, the launch mission was a complete success, and the six satellites were used for space exploration, atmospheric density detection and other related technology verification and test applications.
"Li Jian No. 1" is the "Zhongke No. 1 A" (ZK-1A) carrier rocket. It was developed by Beijing Zhongke Aerospace Exploration Technology Co., Ltd. and is currently the solid rocket with the largest carrying capacity in China.
"Li Jian No. 1" also has the advantages of higher carrying efficiency, shorter preparation period, lower launch cost, etc., and will provide a more powerful solid launch vehicle for China's commercial aerospace market.
