Overview

• Civilian and military tracking confirm that Shijian-21 and Shijian-25 docked in geosynchronous orbit more than 20,000 miles above Earth.
• Observers say the maneuver could represent China’s first high-altitude refueling attempt, potentially extending satellite operational life in critical orbital slots.
• U.S. Space Force inspector satellites USA 270 and USA 271 have repositioned near the docked pair to gather intelligence on China’s on-orbit servicing techniques.
• The operation underscores Beijing’s advancing space-servicing capabilities and raises concerns about dual-use potential to disable or capture other nations’ satellites.
• U.S. military leaders are preparing the first American in-orbit refueling of a military asset as early as next summer to maintain orbital leverage.
