en.Wedoany.com Reported - At 16:52 on August 4, China used the Long March 8A Y10 carrier rocket at the Hainan Commercial Space Launch Site to successfully launch the 23rd batch of low-orbit satellites for the satellite internet. The satellites entered their designated orbits smoothly, and the launch mission was a complete success.

This rocket was developed under the leadership of the First Academy of China Aerospace Science and Technology Corporation. This mission marked the first full-system verification flight of the Long March 8A carrier rocket after a complete performance upgrade, further enhancing the rocket's overall carrying capacity and setting a new record for the total mass injected into orbit for this model. The strong carrying capacity advantage provides solid support for China's future high-density, heavy-payload, and batch networking launch missions.

In this mission, China's hydrogen-oxygen upper stage achieved its first hour-level coasting time in orbit, marking a key step in China's long-duration in-orbit technology development for hydrogen-oxygen upper stages. The hydrogen-oxygen upper stage successfully delivered the satellites directly into the 1,100-kilometer target orbit, achieving a "direct express" function that can save satellites months of orbit-raising time.

The 23rd batch of low-orbit satellites for the satellite internet was developed under the leadership of the Fifth Academy of China Aerospace Science and Technology Corporation.

This launch was the 661st flight of the Long March series carrier rockets.
