China to test satellite refueling in space as US spies watch closely
China is set to conduct a pioneering orbital refueling test involving two satellites, Shijian-21 and Shijian-25, in geostationary orbit (GEO). The test, scheduled for June 11, will see Shijian-25 transfer approximately 313 pounds (142 kg) of hydrazine fuel to Shijian-21, potentially extending the latter’s operational life by eight years. Developed by the Shanghai Academy of Spaceflight Technology, these satellites have already demonstrated complex orbital maneuvers, including Shijian-21’s 2022 docking with a defunct Beidou navigation satellite to move it to a graveyard orbit. This test marks China’s first on-orbit refueling attempt in GEO and represents a significant technological advancement. The United States is closely monitoring the operation through two surveillance satellites, USA 270 and USA 271, part of the Geosynchronous Space Situational Awareness Program. These US satellites have maneuvered to observe the Chinese satellites
