Having assisted with INTELSAT 901’s retirement to the graveyard orbit in early April, MEV-1 — Northrop Grumman’s Mission Extension Vehicle — has returned to GEO and plane-matched with OPTUS D3 at 156.128° E. It is maintaining a separation between 2km - 7km as of May 21.

Update on GSAT-15 (SSN 41028) Earlier report of westward drift were based on preliminary tracking data. We've since confirmed that GSAT-15 remains co-located with GSAT-17 (SSN 42815) near 93.5°E.

Thanks to data from OurSkyAI and observable.space, combined with updates from COMSPOC’s own optical network, our Operations Team was able to detect a maneuver from SHIJIAN-21 (SSN.49330). At 15:49:12 UTC on 2 June 2025, SHIJIAN-21 performed a maneuver of ~10.8 m/s delta V,

Recent observations from OurSkyAI and observable.space, supported by COMSPOC’s optical network, reveal several significant activities in GEO between 6–8 June 2025. SHIJIAN-25 (SJ-25) performed four maneuvers between 6 June 01:50 UTC and 7 June 16:51 UTC, using a total delta-v

Our latest analysis using SSA suite, our commercially available SSA platform, indicates that the Chinese satellite SHIJIAN-25 (SJ-25) continues its steady drift towards SHIJIAN-21 (SJ-21) at approximately 1.5 degrees per day. According to today's state update, their closest

COSMOS 2589 (SSN.64467), a Russian military satellite, was launched on 19 June 2025 aboard an Angara-5 rocket from Plesetsk. Public sources classify it as part of the Ekspress-2000 series, a large 3-ton satellite platform. As of 24 June, COSMOS 2589 occupies an unusual

As of 26 June, SHIJIAN-21 remained less than ~80 kilometers from SHIJIAN-25. Meanwhile, USA 270 continued to occupy the mean longitude position of the pair. According to our Space Situational Awareness (SSA) software suite, both satellites performed several small maneuvers to

On 26 Jun, Object D was officially cataloged by the 18 Space Defense Squadron after its release from COSMOS 2589, a Russian military satellite launched on 19 Jun. This newly released object maintains a similar highly-elliptical orbit. The video demonstrates the orbits of both

UPDATE: SHIJIAN‑21 & SHIJIAN‑25 Proximity Operations in GEO SHIJIAN‑21 (SJ-21) and SHIJIAN‑25 (SJ-25) were observed conducting Rendezvous and Proximity Operations (RPO) in geosynchronous orbit during Jun-Jul 2025 with multiple close approaches. The two objects appeared visually
