In this issue of Integrity Flash (Edition 123), we examine a wave of high-stakes satellite activity, spotlighting a potential first in space operations:
China’s GEO refueling mission – SJ‑21 and SJ‑25 performed coordinated close-proximity maneuvers over geostationary orbit from June 8—16, possibly achieving docking and on-orbit refueling-while U.S. GSSAP satellite USA 270 repositioned itself to monitor the activity.
Zhongxing‑9C launch – China deployed a new 5.5-ton communications satellite to replace Chinasat‑9 and enhance its geostationary communications infrastructure.
Yaogan‑35/36/39/42 formation updates – Chinese surveillance triplets continue lead‑trail formation maintenance, but Trail‑2 satellites are now drifting free of original clusters.
Russia’s Cosmos 2589 launch – A suspected geostationary inspector satellite was deployed into a supersynchronous transfer orbit; analysis suggests it may release mini-inspector subsatellites akin to past Nivelir-equipped platforms.
Retrospective: Cosmos 2542 mission – Revisiting Russia’s 2019—2020 inspector test where Cosmos 2543 shadowed U.S. intelligence satellite USA 245 and released subsatellites and debris-prompting international alarm.
