China’s first launch of 2025 successfully placed an experimental satellite, Shijian-25, into orbit, focusing on cutting-edge satellite fuel replenishment and life-extension technologies.

A Long March-3B rocket carrying the satellite lifted off at 4 a.m. (Beijing Time) on Tuesday from the Xichang Satellite Launch Center in Sichuan Province. Shortly after, the payload was delivered into its designated orbit.

Developed by the Shanghai Academy of Spaceflight Technology, Shijian-25 is designed to test and validate critical capabilities that could extend satellite lifespans and improve their in-orbit performance.

Tuesday’s launch marked the 555th mission in the Long March series of carrier rockets.
