On the 20TH December 2024 schedule to launch CNSA _China National Space Administration -China – People’s Republic of China 2312 Hours Hong Kong –Beijing Time China- People’s Republic of China…. at the Xichang Satellite Launch Center, Sichuan Province At 23:12 on December 20, the Long March 3B carrier rocket ignited and took off from the Xichang Satellite Launch Center, and then accurately sent the Communication Technology Experimental Satellite No. 12 into the predetermined orbit. The launch mission was a complete success.
The Long March 3B rocket was developed by the First Academy of China Aerospace Science and Technology Corporation. This launch is another victory for the Long March 3B rocket after it achieved my country’s first 100th space launch of a single model on December 3. The two launches were only 17 days apart, and it is also the final battle of the Long March 3A series of launch vehicles in 2024.
In response to the needs of high-density launch missions, the rocket launch test team innovatively proposed de-tasking and other management methods and processes. The Long March 3A series of rockets became the first launch vehicle in China to carry out batch production and use dual-station cross-parallel comprehensive testing, final assembly and factory testing. It is also the first launch vehicle that can enable a team to carry out test launches of two rockets at the launch site at the same time, with a launch being carried out once every 15 days.
In addition, in recent years, the rocket development team has continued to promote the implementation of reliability and carrying capacity improvement projects, and completed a new upgrade of the “gold medal rocket” Long March 3A series, laying a solid foundation for a new round of high-density launch missions.
The Communication Technology Experimental Satellite No. 12 was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It is mainly used for satellite communications, radio and television, data transmission and other services, and carries out relevant technical tests and verifications.
During the mission, the rocket launch test team and satellite test team of the China Aerospace Science and Technology Corporation took Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era as their guide, thoroughly studied and implemented the spirit of the 20th National Congress of the Communist Party of China and the Second and Third Plenary Sessions of the 20th Central Committee of the Communist Party of China, conscientiously conveyed and studied the spirit of the Ninth Working Conference of the Group Company, gave full play to the leadership role of the temporary party committee, the role of the party branch as a fighting fortress, and the vanguard and exemplary role of party members, unified their thinking, gathered their strength, and strived to be the first to ensure the complete success of the launch mission.
On the 3rd December 2024 schedule to launch CNSA _China National Space Administration -China – People’s Republic of China 1356 Hours Hong Kong –Beijing Time China- People’s Republic of China…. at the Xichang Satellite Launch Center, Sichuan Province at the At 13:56 Beijing time on December 3, 2024, at the No. 2 launch station of the Xichang Launch Center, the Long March 3B carrier rocket was launched, sending the Communication Technology Experimental Satellite No. 13 into the geosynchronous transfer orbit (GTO).

The Communication Technology Experimental Satellite No. 13 is mainly used for satellite communications, radio and television, data transmission and other services, and carries out relevant technical tests and verifications. The
Long March 3B modified type 2 (CZ-3B/G2) has a total height of 56.326 meters, a maximum core stage diameter of 3.35 meters, a booster diameter of 2.25 meters, a takeoff mass of 458.97 tons, and a maximum capacity of 5.55 tons in the standard geosynchronous transfer orbit (GTO).
From its first flight on February 15, 1996 to this launch, the Long March 3B rocket has carried out 100 launch missions in the past 28 years, with 98 successes (including 2 partial successes), and a success rate of 98%. So far, the Long March 3B rocket has become China’s first single-model rocket to complete 100 launch missions.
This mission is the 7th launch of the Long March 3B rocket in 2024, the 17th launch from the Xichang Launch Center, the 60th launch in China and the 230th orbital space launch in the world.
[This satellite badge of Third Aunt’s launch is very interesting]
At 13:56 on December 3, the Long March 3B carrier rocket ignited and took off from the Xichang Satellite Launch Center, and then successfully sent the Communication Technology Experimental Satellite No. 13 into the predetermined orbit. So far, the Long March 3B carrier rocket has officially entered the “100 Launch Club”, becoming the first single-model Long March rocket in China to have exceeded 100 space launches.
Figure 1 is the satellite badge of Third Aunt’s launch mission. The Monkey King Sun Wukong and the golden hoop are very eye-catching. And this time Third Aunt launched during the day, which is interesting.
