A paired Shijian-29 test system has tightened its formation in the geostationary belt to roughly 30–35 km — the closest the two have flown — while the U.S.…
29 May 2026: Russia conducted significant plane change maneuvers with 5 Cosmos satellites. Plane change maneuvers are rare in space operations, especially in Low Earth Orbit (LEO) due…
7 May 2026: Chinese space operators increased the average altitude of SJ-23 (55131) ~105km to reverse its eastward drift. The maneuvers occurred as the satellite approached 175°E Longitude,…
1 May 2026: COMSPOC_OPS reported that the rendezvous proximity operations between Cosmos 2581, 2582 and 2583 (62902, 62903 & 62904) are continuing. Their latest reporting was specific to…
3 May 2026: As we noted in previous Flash editions, Cosmos 2589 (64467) had nearly completed its orbit circularization and USA 325 (51281) looked to be heading in…
17 Apr 2026: Over the next 2-3 weeks both USA 325 and TJS-10 will pass through Cosmos 2589's orbit. As we began reporting in November 2025, Cosmos 2589…
5 Apr 2026: Suspected Chinese inspector satellite Shiyan-12 02 (50322) passed ~71km of Iran’s new GEO satellite Jam e Jam 1 (67757). The fly-by opportunity occurred at ~34°E…
4 Apr 2026: From 30 Mar - 1 Apr Chinese space operators decreased the SMA for TJS-10 (58204) nearly 200km. The maneuver reversed TJS-10's ~1.9°/day westward drift and…
21 Mar 2026: At ~1550Z on 20 Mar, TJS-10 (58204) and TJS-3 (43874) passed one another in GEO over ~91.5°E longitude. Neither satellite maneuvered (at least as of…
5 Mar 2026: As noted in the last edition of the Flash , Chinese space operators maneuvered both TJS-10 (58204) and TJS-3 (43874) in early February resulting in…
4 Mar 2026: SJ-21 (49330) and SJ-25 (62485) remain separated by ~560-640km with SJ-21 located to the east of SJ-25. The two orbits are plane-matched and the vast…
6 Mar 2025: Russia continues to maneuver Cosmos 2589 (64467) closer to a circular Geosynchronous Orbit. Russia has been regularly increasing the satellite’s perigee and decreasing its apogee…
15 Feb 2026: As noted in the last edition of the Flash , on 3-4 Feb Chinese space operators increased the SMA of TJS-10 (58204) and initiated a…
7 Feb 2026: China appears tohave conducted a closeapproach between Shiyan-32 02 (66378) and Shiyan-32 03 (66379). From 13-20 Jan, Chinese space operators conducted 3 in-track maneuvers and…
6 Feb 2026: As we noted in the previous flash, SJ-21 (49330) and SJ-25 (62485) exited RPO conditions in mid-January. They are now approximately 600km apart with SJ-21…
16 Jan 2026: SJ-21 (49330) and SJ-25 (62485) may have exited RPO conditions in mid-January. Before doing so China appears to have used both spacecraft to train on…
14 Jan 2026: In November 2025 China launched two sets of 3 satellites into nearly co-planar orbits with dozens of Starlink and Amazon LEO satellites. On 8 Nov…
