Issue 149 of Integrity Flash is now available.

If space operations, ISR, and national security matter to your mission, this week's issue is worth your time.

Read Issue 149 today at https://t.co/qSsmhsqpOu

@shell_jim Great work Jim! Alas, I was hoping this was GF-13 02 as it would help to explain TJS-3's recent maneuvers. https://t.co/LR75Ref3lm

@planet4589 I think this might be the first Southern Molniya orbit. As Mickey points out Arg of Perigee is 171, RAAN is 355. Apogee is over the Southern Hemisphere.

[Greg Gillinger @GillingerGreg]

@Skyrocket71 @planet4589 this is the first SJ in Molniya. Joins 2x SY-10 and 2x TJS. TJS and SY satellites are paired so they reach apogee around the same time. Typical for missile warning.

There’s a stakeout in GEO, and the U.S. Space Force needs more eyes. https://t.co/GrbStioURn

@wulei2020 Now if could just not leave its upper stage in orbit for the next couple of hundred years. Irresponsible.

[Greg Gillinger @GillingerGreg]

@vantortech @NGA_GEOINT Amazing stuff. This looks to be either AIRSAT 3 or 4 (2025-234). Write up in Gunther's https://t.co/3NFqSQhrVX

@Cosmic_Penguin Note SY-12 01/02 also rode a LM-7A to GEO back in Dec 2021 and have been cruising the GEO belt ever since.

[Greg Gillinger @GillingerGreg]

@AJ_FI got it, thanks Andrew. Getting pretty sporty these days!

[Greg Gillinger @GillingerGreg]

@planet4589 I suspect this will join TJS-13 & SY-10 01 and 10 02 to provide 24/7 2 satellite coverage of the northern hemisphere. Most likely missile warning mission.

[Greg Gillinger @GillingerGreg]

@planet4589 I can't find any information regarding this launch in the catalog. Not even the international designator. I believe it should be 2025-248...but only because that is the only number missing in the past 30 days.

[Greg Gillinger @GillingerGreg]

@COMSPOC_OPS Always great to collaborate with the @COMSPOC_OPS team!

I think this may be the most glorious footage we've seen from orbit this year. What a view! 🌏

What is your fav shot from 2025?

[Greg Gillinger @GillingerGreg]

@AndrewSErickson @WillRinehart @B_Mulvaney @usairforce @USSpaceForce @BluePathLabs Thanks Andrew...new edition coming out on 27 Oct!

[Greg Gillinger @GillingerGreg]

The satellite remains 28.5 deg inclined. With this maneuver SY-29 is likely NOT some sort of GEO inspection satellite and is intended for other experimentation.

[Greg Gillinger @GillingerGreg]

Per Joint Capabilities Operations Cell (JCO) reporting it appears as if China completed a significant maneuver of SY-29 (65486) on 30 Sep. The satellite (launched 5 Sep 2025) had been orbiting above the GEO graveyard orbit and drifting westward ~5.5 deg/day.

[Greg Gillinger @GillingerGreg]

On 30 Sep, China significantly decreased SY-29's average altitude (apogee -524km and perigee -50km) nearly eliminating its westward drift. The satellite is now just above GEO at 102.18deg E longitude (centerline of mainland China) and drifting west at only 0.725 deg/day.
