China's Long March 12 rocket successfully launches Satellite Internet Low-Earth-Orbit Group 29 satellites

en.Wedoany.com Reported - At 4:24 on November 9, China successfully launched the Satellite Internet Low-Earth-Orbit Group 29 satellites into space from the Hainan Commercial Spacecraft Launch Site using a Long March 12 carrier rocket. The satellites smoothly entered their predetermined orbit, and the launch mission was a complete success. This mission was carried out by the Long March 12 carrier rocket, and the satellites were developed under the overall leadership of the Fifth Academy of China Aerospace Science and Technology Corporation.

The Long March 12 carrier rocket was developed under the overall leadership of the Eighth Academy of China Aerospace Science and Technology Corporation. It is a new-generation cryogenic liquid propellant carrier rocket and also China's first single-core-stage carrier rocket with a 4-meter-class fairing diameter. The rocket has a total length of approximately 62 meters and a carrying capacity of no less than 6 tonnes to a 700-kilometer sun-synchronous orbit. It can be equipped with a 4.2-meter or 5.2-meter diameter fairing according to mission requirements and supports single-satellite, multi-satellite, and various orbit launch missions.

This rocket adopts a two-stage configuration, with a low-Earth-orbit carrying capacity of no less than 12 tonnes and a 700-kilometer sun-synchronous orbit carrying capacity of no less than 6 tonnes. The fairing configurations of different diameters enable it to accommodate satellite payloads of different sizes and quantities, providing multi-satellite launch and transport capability for low-Earth-orbit satellite constellation missions.

This launch was the orbit insertion mission for the Satellite Internet Low-Earth-Orbit Group 29 satellites and was also the 676th launch of the Long March series of carrier rockets. Previously, the Long March 12 successfully launched the Satellite Internet Low-Earth-Orbit Group 27 satellites from the Hainan Commercial Spacecraft Launch Site on October 10, 2026, using the same rocket model to carry out the low-Earth-orbit satellite constellation mission.
