Two Chinese satellites, Shijian-21 and Shijian-25, docked in geostationary orbit 22,000 miles above Earth between June and July 2025.
US tracking companies COMSPOC and Swiss firm s2a systems observed the satellites merging for days, suggesting fuel transfer occurred. Shijian-25, launched in January 2025, was designed to test refueling capabilities.
Shijian-21 had previously used most of its fuel towing a dead satellite to graveyard orbit in 2022. This breakthrough technology is crucial for future deep space missions and Mars exploration.
