China successfully launched two experimental satellites, Shiyan-30 03 and 04, from the Xichang Satellite Launch Center in Sichuan Province on March 13, 2026. The satellites, developed by the Shanghai Academy of Spaceflight Technology (SAST), were carried into preset orbit by a Long March-2D rocket at 6:33 a.m. local time.
The mission aims to validate advanced Earth observation technologies, enhancing capabilities in environmental monitoring, resource management, and disaster response. The Long March-2D rocket, a liquid-propellant vehicle designed by SAST, demonstrated its versatility by deploying multiple satellites into precise orbits. With a payload capacity of 1.3 tonnes to a 700-kilometer sun-synchronous orbit, the rocket underscores China’s growing proficiency in space logistics.
This launch marks the 632nd flight of the Long March series, reflecting China’s sustained investment in space exploration and technological innovation. Analysts note that such missions align with broader goals to strengthen scientific research and international collaboration in Earth observation systems.
