@sundogplanets probably you already knew this but i just came across this thanks to a colleague of mine that sent me tho link. Amazon satellites are pretty bright --> https://arxiv.org/pdf/2601.07708

Abstract: "The mean apparent magnitude of Amazon Leo satellites is 6.28 based on 1,938 observations. For spacecraft in their operational mode, 92% exceeded the brightness limit recommended by the IAU for interference with research, while 25% distract from aesthetic appreciation of the night sky. The reflective characteristics are similar to Version 1 Starlink spacecraft."

CSE's own @sundogplanets (University of Regina) has a new article with Gregory Radisic (Bond University) in @TheConversationUS in which they argue that the rapid expansion of #satellite #megaconstellations poses a catastrophic threat to Earth's orbit and the cultural heritage of the night sky and advocate for a Dark Skies Impact Assessment to regulate these impacts before they become irreversible.

Senate committee delays consideration of bill to streamline FCC satellite licensing

🗨️ 👩🏽‍💻 Evil #iran, of course - and that's why the noble world now needs #starlink to give free rein to the real #US threat from lower orbit - that's what I call a clear political classification, and not a finding from #research that would actually offer the global population #protection from real catastrophes in crisis, right?

SpaceX files plans for million-satellite orbital data center constellation

"The sky is getting crowded. In the last few years, the number of #satellite launches has increased by an order of magnitude as #megaconstellations of internet-powering hardware crowd into low Earth orbit. The pace of both launching and retiring these units is creating new kinds of #pollution, potentially upsetting the #climate system and the protective #ozone layer."

Oh, FFS!

I just looked outside, it's a nice clear morning, still dark. Jupiter certainly looks beautiful next to Castor and Pollux, and oh, look, FOUR FUCKING SATELLITES EACH AT LEAST AS BRIGHT AS CASTOR AND/OR POLLUX.

That doesn't ruin the constellations or the night sky at all, does it?

Yet another reason to hate #Starlink and other #Megaconstellations flooding #LowEarthOrbit:

• That shit severely harms the #ozone layer and I hope that reentries of satellites will be disallowed like blowing #CFC11!

A @Nature paper published today argues that "Satellite megaconstellations will threaten space-based astronomy" https://www.nature.com/articles/s41586-025-09759-5

Here's the punchline of the paper: satellites could be a problem even for orbiting space telescopes, but the impact depends on how many are launched. "Our results show that if these constellations are completed, one-third of the images of the Hubble Space Telescope will be contaminated, while the SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), ARRAKIHS (Analysis of Resolved Remnants of Accreted galaxies as a Key Instrument for Halo Surveys) and Xuntian space telescopes will have more than 96% of +0.3 their exposures affected, with 5.6^+0.3_−0.3, 69^+21_−22, and 92^+11_−10 trails per exposure, respectively, with an average surface brightness of μ = 19 ± 2 mag arcsec−2."

“We find that LEO #megaconstellations provide substantially improved #broadband speeds for rural and remote communities but are roughly 6-8 times more emissions intensive (250 kg CO2eq/subscriber/year) than comparative terrestrial 4G mobile broadband. Policy makers must carefully consider the trade-off between improving broadband #Internet to further the #SDGs while mitigating the growing #space sector environmental footprint, particularly regarding phase 2 plans to launch an order-of-magnitude more #satellites.”
