29 Jan 2026: As noted in the 18 Jan 2026 edition of the Flash, China launched Shijian-29A and Shijian-29B satellites (67302 & 67303) to GEO on 30 Dec 2025. We also noted that the SJ-29 pair settled into GEO at 73.0°E longitude with an inclination of 3.1°. What we didn’t know at the time of publishing was that USA 325 (51281), one of the United States’ Geosynchronous Space Situational Awareness Program (GSSAP) satellites, was busy getting into position to characterize the SJ-29 pair. Currently the two SJ-29 satellites are maintaining a separation of Thanks to the 30-70km of one another and occasionally within 100km of USA 325. COMSPOC_OPS team for their insights! Please check out this video! – SJ-29A and 29B remain in a co-planar orbit with an inclination of 3.1° and a RAAN of 98.67°.

USA 325 is not co- planar and has an inclination of 0.3° and a RAAN of 86.14°. -SJ-29A does not appear to have maneuvered since arrival on orbit. SJ-29B has made minor maneuvers. As a result the two satellites remain within 70km of one another. SJ- 29A is to the west of SJ-29B. -USA 325 remains within 2,000km of both satellites. The difference in inclination is the principal contributor to this separation. -At the point of closest approach USA 325 is <30km of SJ- 29A and B.

• As the SJ-29A/B pair move from north to south in their orbit USA 325 is closest to SJ-29A. SJ-29A is <100km Lighting conditions were marginal for both satellites to image one another at point of closest approach. (see graphic)
• As the SJ-29A/B pair orbit from south to north USA 325 is closest with SJ-29B. SJ-29B is <100km from USA 325 for ~22min. Lighting conditions were favorable for USA 325 to image SJ-29B at the point of closest approach. (see graphic)

– Based on their on-orbit operations it appears China is conducting some sort of on-orbit testing between SJ-29A and B…it also appears that USA 325 has positioned itself to observe/characterize both satellites for 45min/day withTransiting to the North, SJ-29B will be varying lighting conditions.

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 located to the east of SJ-25. Both satellites have conducted minor “in-track” maneuvers (changes to their SMA) to create the separation. Of note, the two remain co-planar with a radial-track separation of <20km and a cross-track separation of only 300m. A reminder that in-track maneuvers are by far the least expensive in terms of energy (fuel). Should Chine desire to do so they could quickly and cheaply return to RPO conditions between these two satellites.

Previously, I pointed out that according to publicly available TLE data, it appeared SJ-21 and SJ-  25 conducted 7-8 extremely close (<1km) Rendezvous Proximity Operations (RPO) with one another between 1-15 January 2026.  As a reminder, TLE data is an average of multiple observations and works great when objects have adequate separation (let’s say >10km). However, once objects near one another the chances for cross-tagging and other errors grows. So, to get a more accurate understanding requires carful analysis of sensor ephemeris data. With this in mind I asked the COMSPOC OPS team to have a look with their sensor data (and to do the painstaking orbital analysis.) Their results differed from the TLE-based analysis. Based on this analysis, COMSPOC found a minimum range of approximately 2.83 km was reached on 13 Jan 2026 and the satellites were often within 5km of one another but did not perform “Zero Prox Ops” as the TLE data suggested. COMSPOC was even nice enough to create a video to show the differences between their ephemeris based analysis and that based on TLE information.

Guowang Family Analysis by LeoLabs (as of 23 Jan 26)

By Dr Darren McKnight, LEO Labs Senior Technical Fellow

Dr McKnight at LEO Labs has been doing some comparative analysis of Radar Cross Section (RCS) values across the growing family of Guowang satellites. Below is his report which concludes that China is launching slightly larger satellites into their 86.5° inclined orbits when compared with the satellites heading into their 50.0° inclined orbits. Thank you Dr McKnight!

China in Space reported on January 14, 2026, the Guowang satellites launched by the Long March (LM) 5B are larger than the satellites launched by the LM-12 or LM-6A. It was interesting that they did not mention Long March 8A even though there have been more Guowang launches using a LM-8A than any other variant (i.e., seven by LM-8A, six by LM-6A, four by LM-12, and three by LM-5B). An examination of the first 11 of the 19 batches of Guowang satellites does indeed show a differentiation in size of spacecraft but it does not exactly align with public statements. The table below summarizes radar cross-section (RCS) values for 86 of the on-orbit Guowang spacecraft during 2025. This RCS data is an aggregation of over 30,000 RCS measurements taken by LeoLabs.

Consistent with the public statement, spacecraft deployed by the LM-5B appear to be consistently larger (by about 30%) than the spacecraft deployed by the LM-12. There is also strong correlation between objects launched by LM-8A missions with those deployed by LM-12. However, the spacecraft deployed by LM-6A appear to be similar in size to the ones launched by the LM-5B. The difference is not large enough to be statistically significant, especially since the ranges (i.e., minimum to maximum) of RCS values have significant overlap between LM-5B and LM-6A missions.

In examining the table above, the stronger correlative factor does not appear to be the launch vehicle used but rather the inclination of the batch deployed; the payloads populating the 86.5° inclination planes are generally larger than the ones going to a 50.0° inclination.

While there has been speculation that Guowang has three vendors manufacturing Guowang satellites, if that is indeed the case, it makes sense that there might be two of the “high inclination” systems, however, we have only moderate in confidence in assessing two different types of satellites being launched into the planes with an inclination of 86.5°.

We have high confidence that the lower inclination deployments are currently using slightly smaller spacecraft than for the higher inclination planes and that LM-8A and LM-12 missions are deploying the same spacecraft.

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 increased SY-32 03’s SMA 8.5km to 450.1km. About a week later, from 28 Jan – 7 Feb, Chinese space operators conducted 3 in-track maneuvers and increased SY-32 02’s SMA ~4.8km. On 1 Feb ~1700UTC SY-32 02 passed SY-32 03 and had a point of closest approach of ~2-5km. At the time of closest approach solar conditions favored SY-32 02 to image SY-32 03 (we do not know if either spacecraft has this capability). SY-32 02 maneuvers on 2 Feb and 7 Feb had the effect of matching SY-32 02’s SMA with SY-32 03 and the satellites are now maintaining a separation distance of ~230km with SY-32 02 in lead position. Of note, SY-32 01 (66376) appears to have suffered some anomaly. It has not maneuvered since its arrival on orbit and its SMA has decreased to 430km or 20km lower than SY-32 02 & 03.

We first mentioned the SY-32 triplets when they launched into a near co-planar orbit with hundreds of Starlink and a few Amazon LEO satellites.

7 Feb 2026: On 3 Feb 2026 Chinesespace operators increased the SMA of TJS-10 (58204)?~140km and initiated a 1.8°/day westward drift. TJS-10 had been at 173.0° E longitude for the past 10 months (April 2025) and has been within 171-173.5°E since arriving on orbit in November 2023. Readers may recall TJS-10 had a visitor in the form of TJS-3 for its first year on orbit. TJS-3 loitered to the West of TJS-10 for the first 6 months (Nov 2023-May 2024) and then both spacecraft maneuvered to place TJS-3 to the East of TJS-10 for another 6 months (May-Nov 2024). With the experiment apparently completed, TJS-3 then headed west. As of 7 February, TJS-10 is at 166.4° East longitude, the furthest west it has ever been.

7 Feb 2026: Chinalaunched a Long March-2F carrying an unmanned space plane (likely the Shenlong) to Low Earth Orbit. This is the 4th time China has launched a re-usable satellite, China also launched its space plane in September 2020 (2-day duration), Aug 2022-May 2023 (276-day duration) and then Dec 2023-Sep 2024 (266-day duaration). In previous missions the spaceplane has released smaller objects on orbit and then conducted RPO with those objects. Chinese official media noted, “The experimental spacecraft will conduct technical verification of reusable spacecraft as planned, providing technical support for the peaceful use of outer space.” Very few details are known about the Shenlong spacecraft. However, German astronomer Felix Schöfbänker captured some amazing images and even video of the Shenlong in 2024 during its third mission. Maxar also collected an image of the spaceplane while in orbit. In spite of the secrecy surrounding the program, China made a point to prominently display the launch fairing and other launch articles. They even made a TikTok Video!

26 Jan 2026: China is accelerating efforts to master reusable rocket technology, a capability critical to lowering launch costs and increasing mission tempo. According to a Space Daily report by Riko Seibo, China is completing an offshore platform at Oriental Aerospace Port in Haiyang to support testing, launches, and recovery of reusable liquid- propellant rockets, with trial operations expected in early February 2026. Additional reporting by the Global Times indicates this push spans both state and commercial sectors, with early reusable launches, recovery infrastructure, and engine development signaling a broader shift away from expendable systems and toward competitiveness with global leaders in reusable launch.

Previous reporting on China’s ambitions for reusable rocket technology:

• Early recovery demonstrations — Startups such as Space Epoch have achieved controlled ocean soft landings of rocket boosters in June 2025.
• Strategic competition — 2025 Defense One reporting suggests China’s reusable launch efforts are part of a broader strategic push to close the gap with established reusable launch leaders and capture more of the commercial launch and satellite constellation markets.
• Offshore reuse infrastructure — The Haiyang platform enables liquid rocket launch and recovery testing.
• First orbital reuse attempt — LandSpace’s Zhuque-3 marked China’s first orbital flight of a reusable liquid rocket, drawing substantial global attention.
• Recovery network expansion — A Hangzhou offshore base will support booster inspection and reuse.
• Commercial momentum — National aerospace exhibitions highlight rapid progress in reusable launch systems.
• PH-1 suborbital test flight — On 13 Jan 26, CAS Space advances its reusable spacecraft ambitions by carrying out the PH-1 maiden suborbital flight.
• Reusable booster development — On 19 Jan 2026, Long March 12B testing shows continued investment in first-stage reuse.
• Beyond satellites — China Daily report, Zhao Lei states that successful reusable system development supports ambitions beyond satellite launches, including suborbital spaceflight, signaling a diversified trajectory for the space economy.

5 Feb 2026: I thought it was about time to check in on the Russian satellites operating in near-coplanar orbits with high-value US satellites. Thanks again to the SaberAstro crew for their fantastic SBMS application! Important note: Orbital data for the USA satellites courtesy of the McCants catalog. This is the best data I have access to, but it can be out of date. However, significant changes to the orbital planes (their Inclination or RAAN values) of any of the satellites in question is unlikely due to the fuel requirements to do so. With this limitation, please consider the points of closest approach as theoretical.

– Cosmos 2558 (53323)/Obj C (64627) vs USA 326: Many will recall that Cosmos 2558 began to suffer some difficulties in April 2025 (began missing regular orbital maintenance maneuvers). In June 2025 Cosmos 2558 released its sub-satellite (likely inspector satellite associated with the Nivelir system). Since that time Obj C has conducted maneuvers to maintain its orbit (and remain co-planar with USA 326). For its part, Cosmos 2558 has lost 60km in altitude (SMA) and is no longer co-planar with either Obj C or USA 326.

Russia: Checking in on the Nivelirs Continued

Cosmos 2576 (59773) vs USA 314: After its launch in May 2024, Cosmos 2576 gradually?increased its altitude (SMA) from 440kmto ~485km. Cosmos 2576remains nearly co-planar with USA 314. Cosmos 2576 is signficantly lower (155km) than its target (at least for the last TLE we received for USA 314 back in August 2025).

Cosmos 2588 (64095) vs USA 338: Perhaps indicating at new tactic, the latest of Russia’s Nivelir satellites, Cosmos 2588, is maintaining a higher orbit (+91km) than its target, USA 338. We have a fairly updated TLE for USA 338 (20 Jan 2026).

5 Feb 2026: Russialaunched a Soyuz 2.1B from Plesetsk carrying 9 payloads (67674-67682) to? Earth Orbit (LEO). Russia announced only that the satellites were for the Ministry of Defense. Per Orbital Focus, the objects were released into different orbits. The first, and assumed primary, payload was released into a 326x329km orbit with an inclination of 96.65deg. The Fregat upper stage then maneuvered and released the remaining objects in a 500km orbit with the same inclination. Orbital Focus noted the Fregat released the 8 satellites in 2 batches. The first contained 4 objects, then the Fregat maneuvered to change RAAN 2.5° east and then released the remaining 4 satellites. Satellite mission and payload remain unknown, however the orbital parameters (and operational requirements) suggests imagery satellites.

The SpaceReview released an article, “The Successful Development of Russia’s Counterspace Activities in LEO and GEO” by Matthew Mowthorpe and Markos Trichas which analyzes Russia’s expanding counterspace capabilities, highlighting recent advances that showcase Moscow’s ability to develop and operationalize anti-satellite (ASAT) systems in both low Earth orbit (LEO) and geosynchronous orbit (GEO). These developments—some conducted under the cover of experimental space systems—reflect Russia’s strategic intent to challenge U.S. and allied space assets through co-orbital interceptors, ground-based ASAT missiles, and other offensive technologies.

Summarized insights from Mowthorpe and Trichas SpaceReview article:

• GEO Nivelir ASAT deployment – Russia has successfully developed and begun fielding Nivelir co-orbital anti-satellite systems in geosynchronous orbit.
• Co-orbital ASAT operations in LEO – Multiple Cosmos satellites have conducted rendezvous, proximity operations, and inspection maneuvers indicative of kinetic interceptor roles.
• Ground-based direct-ascent ASAT (Nudol) – The Nudol system has been tested repeatedly and is likely operational, capable of intercepting LEO satellites up to ~850 km.
• Historical ASAT development expertise – Soviet and Russian programs have long experience with multiple orbital ASAT system classes, underpinning current efforts.
• Satellite proximity maneuvers – Recent missions show frequent orbit modifications and close approaches to foreign satellites, raising counterspace concerns.
• Dual-use experimental designation – Some systems are publicly framed as experimental or observational while testing counterspace functions.
• Potential nuclear ASAT research – There are indications Russia has explored or pursued orbital nuclear counterspace weapons as part of its threat set.
• Integrated offensive suite – Russia’s counterspace posture includes both space-based co-orbital systems and ground-based direct-ascent interceptors, offering layered offensive options.
