This feels like a good moment to remember a small tribute from a while back: in 2013 I dedicated an asteroid to Thomas Pynchon — (152319) Pynchon

¡VIVA LA REVOLUCIÓN!

🚨 Spaceflux observed Russia’s Cosmos 2553 tumbling in orbit. Brightness varied by 0.7–3 mags, indicating a ~2.2s spin period. Optical sensing reveals behavior radar can't see, real-time insights for space security. 🛰️

🚨 Breaking: @spacefluxHQ detects debris cloud from @blueorigin 's New Glenn upper stage!
Captured 17 Jan 2025, 12:54 UTC, likely from propellant release during passivation. 🛰️

🎄 Celebrating our incredible team: Spaceflux Starlit Xmas Soiree 2024 ✨

We came together to celebrate our amazing team & the end of another fruitful year for @spacefluxHQ. The evening was filled with joy, music, presents, & we even presented 3 awards for outstanding employees!

The first videos of the #asteroid #C0WEPC5 entry in #Russia are coming out on @telegram . It appears to be very similar to previous asteroid entires (2022 WJ, 2023 CX1, 2024 BX1). Lots of fragments at the end, it probably dropped some rocks in a remote forested area.

Don't say I didn't warn you... 🤏☄️

C/2024 S1 (ATLAS) has arrived at its final destination!

[spacefluxHQ @spacefluxHQ]

🚨 Intelsat IS-33e Breakup Update 🚨 @spacefluxHQ has been hard at work tracking about 40 fragments from the event. We detected multiple #fragments & UCTs during the observation session in this clip from our Cyprus sensor last night at 21-10-2024 17:43 (UTC). Stay tuned!
