Objects in Moon-orbit-crossing trajectories tend to be chaotic;
the abandoned Chandrayaan-3 propulsion module, left in a 125000 x 305000 km orbit in 2024, had a bit of a tussle with the Moon in November and has now been found in a 365000 x 983000 km x 22 deg orbit

The Shi Jian 25 satellite continues to operate in the vicinity of Shi Jian 21 in geosync drift orbit - currently near 126E - following its docking and refuelling experiment. Space Force has cataloged a third associated object which apparently was released around Dec 22

I am not really good with this kind of observation, but here's my processed version of the JWST observation of the C/2025 K1 comet, which was made today! 🔭
The multiple fragments are clearly visible there, in full beauty

Russia is apparently failing to rebuild the Soviet-era satellite constellation for early warning about ballistic missiles launches, most likely due to inability by the industry to complete new satellites hit by sanctions and financial problems: russianspaceweb.com/eks.html

It appears the Russian Defense Ministry's Olimp-K (Luch, 2014-058A) sat has finally been retired, after visting 30 separate geostationary locations during its suspected eavesdropping mission. The orbit was raised to the graveyard from Oct 7 to Oct 22. The plot shows the sat's orbit height history

ISRO has launched their LVM-3 rocket on the NISAR mission from Second Launch Pad, Satish Dhawan Space Centre.
On board today's mission was the BlueBird Block 2 FM1 cellular broadband satellite.

Observations from Chile suggest that Japan's H3 survived the first orbit and reentered at second perigee, circa 0400 UTC, somewhere over S America along the track shown here

I am going to assume for now that the Space Force elset is accurate, and guess that H3/QZS reentered at first perigee over the S Atlantic at around 0250 UTC.

Possible problem with the H3 launch, looks like the second burn of stage 2 may have shut down early. Waiting for confirmation one way or the other

Last telemetry screen from #H3F8 shows a deviating trajectory unfortunately. I hope they can save the #Michibiki5 satellite!
