On Oct 19, Intelsat IS-33e broke up in geostationary orbit. Our Cyprus sensor captured fragments just hours after the event. More updates soon! 🚀

🚨 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!

The first videos of the #asteroid #C0WEPC5 entry in #Russia are coming out on Telegram Messenger . 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.

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

🚨 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. 🛰️
