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.

中国的First Ocean Salinity Detection Satellite was successfully launched

At 1241 Hours Hong Kong SAR- Beijing Time 14th December 2024 , China- People’s Republic of China- CNSA –China National Space Administration   Successfully launched  Chang Zheng – Long March 6 Carrier Rocket ignited and took off at the Taiyuan Satellite Launch Center Shanxi Province..

[The third launch of the Long March 6-modified Qianfan rocket was a success!]

At 12:41 on December 5, the Long March 6-modified carrier rocket soared into the sky at the Taiyuan Satellite Launch Center, and then sent the Qianfan polar orbit 03 satellite group into the predetermined orbit, and the launch mission was a complete success.

The Long March 6-modified rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It is a new generation of non-toxic and pollution-free carrier rocket, and it is also China’s first solid-liquid bundled medium-sized carrier rocket. The carrying capacity of the 700-kilometer altitude sun-synchronous orbit is greater than 4.5 tons.



During this mission, the Long March 6-modified rocket encountered the coldest weather since its first flight. A few days before the launch, the Taiyuan Satellite Launch Center welcomed the first snow of this winter, and the lowest temperature once dropped to minus 26 degrees Celsius. In response to this, the test team worked closely with the launch site to add insulation measures to the tower and increase the air supply temperature of the air conditioner; by adopting the zero-second detachment technology of the rocket air conditioner connector, the rocket and the satellite in the fairing can “enjoy the warm air of the air conditioner” until the last moment before takeoff, providing better protection for the satellite environment. In addition, the rocket test team and the launch site carefully selected the relatively high temperature at noon to transfer and launch the rocket to ensure that all work was fool proof.


The Chang Zheng – Long March 6 modified rocket continued to use a stacked layout to implement the “one rocket, 18 satellites” launch mission. The launch of the Qianfan Polar Orbit 03 satellite group was provided by China Aerospace Science and Technology Corporation Great Wall Company as the general contractor. The Qianfan Polar Orbit 03 satellite group includes 18 low-orbit broadband Internet satellites. It is the third batch of satellites of the first generation of Qianfan constellation satellites of Shanghai Yuanxin Satellite Technology Co., Ltd. The first three batches of Qianfan satellites were successfully launched by the ChangZheng – Long March 6 modified Carrier rocket….

“Long March 6A” is a medium-sized solid-liquid bundled carrier rocket developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It adopts a two-and-a-half-stage series-parallel structure. The core stage and the core stage are connected in series, and the core stage is clustered with four boosters. The main power of the core stage is a liquid oxygen-kerosene engine, and the boosters use solid propellant engines.

The whole “Long March 6A” rocket is about 50 meters high (with a standard fairing of 4.2 meters in diameter), the core stage diameter is 3.35 meters, the booster diameter is 2 meters, and the diameter of the fairing is optional. The diameter is 3.35 meters, 3.8 meters, 4.2 meters and 5.2 meters. The takeoff mass is about 530 tons, the takeoff thrust is about 734 tons, and the arrow has a carrying capacity of about 5 tons in a 700-kilometer circular sun-synchronous orbit (SSO). At present, the arrow has further improved its carrying capacity by replacing the YF115B engine that can be restarted twice for the second stage.

During this mission, the Long March 6A rocket encountered the coldest weather since its maiden flight. A few days before the launch, the lowest temperature at the Taiyuan launch site dropped to minus 26 degrees Celsius. In response, the test team and the launch site added insulation measures to the tower and raised the air supply temperature of the air conditioner; by adopting the zero-second detachment technology of the rocket air conditioner connector during takeoff, better protection was provided for the rocket and the satellite in the fairing. In addition, the rocket test team and the launch site also chose the relatively high temperature at noon to transfer and launch the rocket.

On October 15, 2024, the Long March 6A Yao 20 rocket carried out the launch mission of the 18 satellites of the Thousand Sails polar orbit 02 group, 51 days after this launch mission. At present, the Long March 6A carrier rocket has entered the high-density launch phase, and the model continues to optimize the personnel configuration, ground equipment recovery, test operation procedures, etc., to further shorten the launch interval to meet the future intensive launch needs.

The “Qianfan” constellation is the G60 Global Multimedia Satellite (GMS) constellation, a giant low-orbit Internet satellite constellation launched and operated by Shanghai Yuanxin Satellite Technology Co., Ltd. The satellites are designed and manufactured by Shanghai Gesi Aerospace Technology Co., Ltd. The constellation aims to provide space-based broadband Internet services covering the world. The first phase of the constellation plans to launch 108 satellites in 2024, and then launch 1,296 satellites before 2027, and ultimately plans to launch more than 12,000 satellites.

The “Qianfan” polar orbit 03 group is the first generation of satellites in the “Qianfan” constellation and the third batch of networking satellites. So far, the number of satellites launched into space in the “Qianfan” constellation has reached 54. This batch of satellites uses the stackable flat-panel satellite platform independently developed by Gess Aerospace. In December 2023, Gess Aerospace’s G60 satellite digital factory was officially put into production and the first batch of satellites were rolled off the production line. In the future, it will be able to achieve a production capacity of about 1 satellite per day, with an annual output of about 300 satellites. The “Qianfan” constellation is China’s first giant low-orbit constellation to enter large-scale continuous networking launches.

The improved version of the Zhuque-2 (ZQ-2E) launch vehicle uses the basic first stage and a deeply improved second stage. The improvements of the second stage are mainly reflected in the structural system and power system. In terms of the structural system, the improved second stage adopts a single-layer common bottom tank and tunnel delivery pipe scheme, which simplifies the structure and reduces the stage height and rocket body mass.

“Tian Que-15A” (TQ-15A) vacuum liquid oxygen-methane engine test run

In terms of the power system, the second-stage main engine was replaced by the vacuum-type “Tian Que-12” (TQ-12) with the vacuum-type “Tian Que-15A” (TQ-15A) liquid oxygen-methane engine. The latter has significantly improved thrust and specific impulse and has the ability to start three times. At the same time, the second-stage “Tian Que-11” (TQ-11) swimming engine was removed and replaced by the “Yun Que 10” (YQ-10) auxiliary power system. “Yun Que 10” is used for the second-stage precise attitude adjustment, terminal speed correction, propellant sinking, orbit change, and deorbit.

Improved version of the Suzaku-2 launch vehicle

The improved version of the “Zhuque-2” (ZQ-2E) rocket is 47.3 meters high, with a first and second stage and fairing diameter of 3.35 meters, a takeoff mass of 219 tons, a takeoff thrust of 282 tons, and a 500-kilometer sun-synchronous orbit (SSO) capacity of 4 tons. Compared with the basic version of the “Zhuque-2”, the improved version has a height reduction of 2.2 meters, a takeoff mass reduction of 1 ton, a takeoff thrust increase of 14 tons, and a 500-kilometer sun-synchronous orbit capacity increase of 2.5 tons.

Improved version of the Suzaku-2 launch vehicle

The improved version of the Zhuque-2 rocket has created many firsts in China’s aerospace industry. This rocket is China’s first dual-cryogenic liquid carrier rocket that uses full supercooling and filling, the first time in China to use a dual-cryogenic single-layer common bottom tank for a liquid carrier rocket, and the first time in China that the Tianque-15A engine uses large-size, high-precision niobium alloy nozzle processing and manufacturing technology for large-scale engines. In addition, this mission is the first time that a Chinese carrier rocket has used a probability-based high-wind area flight load calculation method, a stage separation cancellation forward rocket plan, and a rocket glide stage propellant intermittent bottoming plan.

Since its maiden flight on December 14, 2022, Beijing time, the “Zhuque-2” series of rockets has carried out four launches in less than two years, achieving three consecutive victories since the basic Yao-2 mission. In the process, the “Zhuque-2” rocket became the world’s first liquid oxygen-methane rocket to achieve an orbital launch, the first to successfully launch a payload, the first to launch continuously and the first to achieve three consecutive launch victories. The improved Yao-1 of the “Zhuque-2” is the first rocket of the new batch of the “Zhuque-2” series, and since then, the series of rockets has entered a new stage of normalized commercial launches.
