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.

This launch is the 554th launch of the Long March series of launch vehicles.Images and visuals are from their Respectives CMS China Manned SpaceCNSA-China National Space Administration

[Long March 2D rocket/Expedition 3 upper stage successfully launches high-speed laser Diamond Constellation test system – China launches high-speed laser diamond constellation test system

At 15:17 on December 12, the Long March 2D carrier rocket/Expedition 3 upper stage lifted the high-speed laser Diamond Constellation test system and soared into the sky at the Jiuquan Satellite Launch Center. Subsequently, the upper stage sent the five satellites of the system into the predetermined orbit respectively, and the launch mission was a complete success. The Long March 2D rocket and the Expedition 3 upper stage were both developed by the Eighth Academy of China Aerospace Science and Technology Corporation. The Long March 2D rocket has the ability to launch single and multiple satellites with different orbit requirements at the three major satellite launch centers in Jiuquan, Taiyuan and Xichang, and its 700-kilometer sun-synchronous orbit carrying capacity is 1.3 tons. The Expedition 3 upper stage, known as the “space bus”, has the ability to autonomously deploy more than 20 times in rapid orbits, and is mainly used for multi-satellite deployment missions in different orbits.


This launch is the 551st launch of the Long March series of carrier rockets. 
The Long March 2D carrier rocket is a room-temperature liquid two-stage carrier rocket with a takeoff thrust of about 300 tons, corresponding to a capacity of 1.3 tons for a 700-kilometer sun-synchronous circular orbit. It has the ability to launch single and multiple satellites in accordance with different orbital requirements at the three major satellite launch centers in Jiuquan, Taiyuan, and Xichang. The Expedition 3 upper stage is a new type of space transportation tool that uses nitrogen tetroxide and methylhydrazine as propellants, is equipped with a 5kN main engine and an autonomous navigation and guidance system, and has the ability to autonomously maneuver and deploy more than 20 times in rapid orbits. It is mainly used for multi-satellite deployment missions in different orbits, and can directly send multiple satellites to predetermined space locations. It can also play an important role in rapid and flexible entry into space, space maneuvers, and space utilization.

At morning 10th December 2024  Beijing time CNSA –China National Space Administration, the Long March 5B Yao-6 carrier rocket from the Wenchang Space Launch Site in Hainan Province,  China, People’s Republic of China., On the morning of December 10, 2024 Beijing time, the “Long March 5B” Yao-6 carrier rocket and satellite assembly were vertically transferred from the vertical assembly and test plant to the launch tower on a mobile launch platform, and the launch mission preparations entered the final stage

Long March 5B Yao-6 launch vehicle

The Long March 5B/Long March 5B (CZ-5B) is a large cryogenic liquid carrier rocket developed for China’s manned space station project, used to launch the main module of the space station. The rocket adopts a one-and-a-half-stage series-parallel configuration, consisting of a core stage and four boosters. It is China’s first one-and-a-half-stage configuration rocket.

Schematic diagram of Long March 5B

The Long March 5B rocket is 53.657 meters long, with a core stage diameter of 5 meters and a booster diameter of 3.35 meters. It is equipped with a large fairing with a diameter of 5.2 meters and a length of 20.5 meters. Its takeoff mass is about 849 tons, its takeoff thrust is about 1,078 tons, and its low-Earth orbit (LEO) capacity reaches 25 tons. In Asia, the Long March 5B is the rocket with the strongest low-Earth transport capacity in service.

The envelope diameter of the Long March 5B rocket fairing reaches 4.5 meters, and the volume exceeds 345 cubic meters. This is the fairing with the largest diameter, longest length, and largest envelope space in China’s current service, and one of the fairings with the largest envelope space in the world. With large carrying capacity and a “large cargo compartment”, the Long March 5B rocket can also be used with the Yuanzheng 2 upper stage to carry out large-scale multi-satellite launches, supporting China’s giant satellite constellation network. Once launched, the Long March 5B rocket will become the world’s most powerful carrier rocket for giant constellation network launches

It is expected that on the evening of December 15th to 16th, at the 101 launch site at the Wenchang Space Launch Center in China, the Long March 5B Yao-6 carrier rocket/Expedition 2 Yao-2 upper stage will carry out a large-scale multi-satellite launch mission, planning to send the satellites on board into low-Earth orbit.

The payload of this mission comes from the China Star Network Project, which is the China Star Network Low Orbit 01 Group Satellite. China Star Network (SatNet) is a giant satellite constellation in China, including low-orbit and high-orbit satellites, and plans to launch 12,992 satellites. The main body of the China Star Network Low Orbit 01 Group Satellite adopts a trapezoidal design, and its appearance is similar to that of the “One Network” constellation satellite. The constellation satellite using this design needs to be launched using a side-mounted launch based on a central load-bearing cylinder.

Long March 5B Yao-6 launch vehicle

This launch mission will be the fifth launch of the Long March 5B carrier rocket and the 13th launch of the Long March 5 series of rockets. At the same time, this launch will also be the first time that the rocket has carried out an unmanned space launch mission, which will provide a very scarce large carrying capacity for constellation networking.
