China News Agency, Beijing, January 9th. At 6 o'clock on January 9th, Beijing time, China used the Long March 7 modified carrier rocket (hereinafter referred to as the Chang 7 modified rocket) at the Wenchang Space Launch Site to successfully launch the 23rd satellite. China Aerospace has achieved a "good start" for space launches in 2023.
The Changqi Kai Rocket was developed by the First Academy of China Aerospace Science and Technology Corporation. It is a new generation of medium-sized launch vehicle in China. Orbital three-stage liquid bundled carrier rocket, with a geosynchronous transfer orbit carrying capacity of up to 7 tons, filling the gap in the 5.5 to 7 ton carrying capacity of Chinese launch vehicles in high orbits, currently available for two types of rectifiers with a diameter of 4.2 meters and 3.7 meters Cover, with one arrow one star and one arrow double main star launching capabilities.
At 6:00 on January 9th, China used the Long March 7 modified carrier rocket at the Wenchang Space Launch Site to successfully launch the practice 23rd satellite and the test 22nd A/B satellite. The three satellites It successfully entered the predetermined orbit, and the launch mission was a complete success.

It is reported that this mission is the fifth launch mission of the Changqigai rocket. It adopts the basic configuration of a fairing with a diameter of 4.2 meters, and the height of the entire rocket is 60.1 meters.
The Shijian-23 satellite launched this time was developed by the Eighth Academy of China Aerospace Science and Technology Corporation and is mainly used for scientific experiments and technical verification.
It is by far the heaviest satellite launched by China's medium-sized high-orbit launch vehicle.
In this regard, the No. 1 Dean Qichang Rocket Test Team installed a star-rocket interface with a larger diameter.
Wei Yuanming, chief designer of the No. 7 rocket, said that with the development of high-orbit satellites, the satellite envelope will continue to increase. The current 4.2-meter fairing of the new generation of medium-sized rockets may not be able to meet the development needs of subsequent missions. Replace the third sub-stage to form an improved rocket that can adapt to the fairing with a diameter of 5.2 meters, and support the improvement of the overall performance of the rocket through stronger power and a more reasonable structure.

It is understood that as the demand for high-orbit satellite launches continues to grow, the Changqigai rocket will continue to increase production capacity. Currently, it can produce 4 to 6 rounds per year, and it is expected to reach 8 to 10 rounds per year by 2025.
