China Launches Advanced Satellite to Test High-Level Communications

China has successfully launched a new satellite into space to support advanced communications technology testing, marking another milestone in the country’s rapidly expanding space program.

The satellite was launched from the Wenchang Space Launch Site in Hainan Province, located in southern China.

The launch took place on December 20, 2025, at 8:30 p.m. local time, using a Long March-5 rocket, which accurately placed the satellite into its designated orbit.

Purpose of the Satellite

According to Chinese authorities, the satellite will be used for experimental testing of high-level communication technologies. These tests include multi-layered communication systems and the ability to transmit data at very high speeds.

The satellite was developed by the China Academy of Space Technology, one of the country’s leading aerospace research institutions.

Long March-5 Rocket Capabilities

The Long March-5 rocket used for the mission was developed by the China Academy of Launch Vehicle Technology, a company specializing in advanced space launch systems.

The rocket’s payload fairing, which protects the satellite during launch, measures 5.2 meters in diameter and 18.5 meters in height, making it suitable for carrying large and complex space equipment.

A Historic Launch Record

This mission marked the 618th satellite launch by China using Long March rockets, highlighting the country’s growing expertise and consistency in space exploration and satellite deployment.

China continues to invest heavily in space-based communication systems as part of its broader strategy to strengthen global connectivity, scientific research, and technological independence.
