On the 30th December Thursday 2021   in  CNSA _China National Space Administration -China – People’s Republic of China At 0043 morning hours Hong Kong –Beijing Time on an. China successfully launched Satellites using the Chang Zheng Long March 3B carrier rocket at the Xichang Satellite Launch Center Sichuan Province….. successfully launched the communication technology test satellite No. 9 at the Xichang Satellite Launch Center. The Aerospace Science and Technology Group’s last launch in 2021 was a success! The Chang Zheng- Long March Carrier Rocket  Series won 48 battles throughout the year . This mission is the 405th flight of the Long March series of carrier rockets. Looking forward to 2022, pay tribute to China Aerospace


In which only five hours ago it was the 酒泉衛星發射中心On 29th December 2021 Wednesday 1913 Hong Kong SAR – Beijing Time  , CNSA –China National Space Administration  Jiuquan Satellite Launch Center – Inner Mongolia – China – People’s Republic of China successfully Launched the International Iconic Chang Zheng 2D – Long March 2D successfully deploying the The Tianhui-4 satellite launch mission was a complete success, the Chang Zheng 2D – Long March 2D carrier rocket ignited and lifted off at my country’s- China – People’s Republic of China Jiuquan Satellite Launch Center, successfully sending the Tianhui-4 satellite into the scheduled orbit, and the launch mission was achieved. A complete success deployment..!

Successful launch the communication technology test satellite No. 9 into the air. The satellite successfully entered the scheduled orbit, and the launch mission was a complete success… The communication technology test satellite No. 9 was developed by the General Department of Communications and Navigation Satellites of the Fifth Academy. It is a geosynchronous orbit communication technology test satellite, which is mainly used to carry out multi-band, high-speed satellite communication technology verification.

The Chang Zheng Long March 3B carrier rocket has undergone many technical improvements and enhancements Zhang Tao, deputy chief designer of the eleventh room of the General Design Department of Rocket Academy, introduced that the rocket performing this mission mainly has 4 technical status changes, all of which are reliability The growth and commercialization projects mainly include:


1) Optimize the structure of the main shaft of the primary servo mechanism pump to increase its fatigue strength and life;
2) Optimize the three-level servo mechanism dampers to improve the stability of the product;
3) Ground supply in the technical area The gas equipment adopts an intelligent pressure reducing valve, and the pressure adjustment and inflation are more intelligent;
4) The upper arrow cover adopts the integral extrusion molding process for the first time, and the subsequent process can be used for the production of the rocket shell section, which greatly improves the production efficiency.
