Chang-8A Satellite Deployment Enhances Global Internet Accessibility with Ten Innovative Constellations

China Advances Satellite Internet Plans with Successful Long March 8A Launch

August 26, 2025

The Hainan Commercial Space Launch Center witnessed a significant milestone as the Long March 8A carrier rocket successfully deployed ten satellite internet satellites into low Earth orbit. This launch underscores China’s determined efforts to establish a robust global connectivity infrastructure through expansive satellite constellations.

Developed by the First Academy of the Chinese Aerospace Science and Technology Corporation, the Long march 8A stands approximately 50.5 meters tall and weighs 371 tons at liftoff. It possesses a remarkable payload capacity, capable of delivering up to seven tons to a 700-kilometer heliosynchronous orbit, making it a versatile tool for a wide range of missions.

Innovative Launch Procedures Enhance Efficiency

The rocket utilizes a liquid fuel propulsion system,employing a two-and-a-half-stage configuration. The first stage features a liquid oxygen and kerosene module measuring 3.35 meters in diameter, while the second stage integrates a hydrogen-oxygen module of the same diameter, along with dual coupled liquid propellant engines. A 5.2-meter diameter fairing further enhances the vehicle’s adaptability for diverse deployment scenarios.

This particular mission marked a pivotal moment, as the Long March 8A successfully implemented a streamlined “two rockets in parallel” test and launch model at the same launch site.This innovative approach significantly accelerated the launch process, reducing turnaround time by approximately five days. Assembly post-rocket arrival was completed within one to two days, streamlining operations.

National Plan for Advanced Connectivity

The ten satellite groups, specifically designed for satellite internet services in low orbit, were developed and manufactured by the fifth Academy of China’s Aerospace Science and Technology Corporation. These satellites are integral to a national initiative aimed at providing advanced connectivity solutions across expansive geographic areas.

this mission – designated number 591 in the Long March series – solidifies the Chang-8a’s position as a key asset in China’s deployment of advanced communication satellites.
