China marked another milestone in its space program with the successful launch of the Shiyan-21 communication technology test satellite from the Xichang Satellite Launch Center on Friday, November 21, 2025. The Long March-3B carrier rocket lifted off at 6:55 p.m. Beijing Time, delivering the satellite into its predetermined orbit.
Designed to enhance satellite communication capabilities, the Shiyan-21 will support radio and television services, high-speed data transmission, and critical technical verification processes. This launch represents China's latest effort to strengthen its orbital infrastructure amid growing global demand for reliable communication networks.
The mission marks the 609th flight of the Long March rocket series, underscoring China's expanding role in space technology development. Analysts suggest this launch could accelerate advancements in 6G network research and smart city infrastructure across Asia.
As nations increasingly rely on satellite-based systems for economic and security needs, this achievement positions China at the forefront of next-generation communication solutions while contributing to international technological collaboration.
