China successfully launched a new communication technology test satellite on December 20, 2025, at 8:30 p.m. Beijing Time from the Wenchang Space Launch Site in Hainan Province, aboard a Long March-5 rocket that marked the 618th mission in the series. The unnamed satellite entered its planned orbit flawlessly, designed primarily for validating multi-band and high-speed communication technologies to enhance satellite data transmission, broadcasting, and related services. This deployment underscores China's accelerating space ambitions amid global competition, building on prior Shiyan-22 tests from Xichang earlier in December.
The Long March-5, China's heaviest lifter capable of geostationary transfers, blasted off amid clear skies, with the satellite poised for in-orbit experiments advancing 6G precursors and broadband networks. State media highlighted its role in bolstering national comms infrastructure, potentially aiding Belt and Road digital silk road initiatives. No specifics on payload or timeline emerged, but successes like this propel China's 2025 launch cadence toward 100 missions annually.
Observers link it to U.S.-China tech tensions, positioning Beijing as a low-Earth orbit contender alongside Starlink rivals. As the satellite activates, it promises breakthroughs in resilient, high-throughput links for remote sensing and disaster response.
