Long March 12 launches Satellite Internet low-orbit Group 29

A Long March 12 rocket launched the Satellite Internet low-orbit Group 29 satellites from Hainan Commercial Space Launch Site. The mission placed the satellites into planned orbit and was reported as a complete success.

The Long March 12 carried the Satellite Internet low-orbit Group 29 payload into its planned orbit after liftoff from Hainan Commercial Space Launch Site. The launch mission was reported as a complete success.

The satellites are associated with the Fifth Academy of China Aerospace Science and Technology Corporation, while the Long March 12 is associated with the Eighth Academy of the same corporation.

The Long March 12 is described as a new-generation cryogenic liquid-propellant launch vehicle with a 4-meter-class diameter and a single core stage. It is China's first launch vehicle with that diameter and single-core-stage configuration.

The rocket is about 62 meters long and can deliver at least 6 tons to a 700-kilometer sun-synchronous orbit. It can be fitted with fairings 4.2 meters or 5.2 meters in diameter and supports single-satellite or multi-satellite missions to different orbits.

The flight was the 676th launch of the Long March launch vehicle series.

The mission adds a successful flight to the Long March record and provides specific performance data for a new-generation cryogenic vehicle with at least 6 tons of capacity to a 700-kilometer sun-synchronous orbit.

The Group 29 mission follows two earlier Satellite Internet low-orbit launches reported by this site: a Long March 12 launch of Group 27 from Hainan Commercial Space Launch Site on Oct. 10, 2026, and a Long March 8A launch of Group 28 on Oct. 26, 2026.
