On April 24, 2026, China successfully launched four satellite-internet technology demonstration spacecraft aboard a Long March 2D rocket from the Xichang Satellite Launch Center. The mission deployed test satellites for SatNet, China's state-owned low Earth orbit communications constellation designed to provide global broadband connectivity. The payload comprised two satellites developed by Galaxy Space and two by Chang Guang Satellite Technology Co, marking collaborative progress toward establishing indigenous Chinese satellite-internet infrastructure to compete with existing international mega-constellations.

The Long March 2D, a reliable medium-lift launch vehicle operated by the China Aerospace Science and Technology Corporation, delivered the satellites to their intended orbit. Xichang, located in Sichuan Province, served as the launch site for this mission, continuing its role as a primary facility for China's satellite deployment operations.

The launch proceeded without complications, achieving mission success and advancing China's satellite-internet ambitions. The successful deployment of these test vehicles represents an important step in validating technologies and operational procedures for SatNet's broader constellation development, strengthening China's position in the competitive global space communications sector.
