SpaceX Starlink and other satellite megaconstellations are creating an 'unregulated geoengineering experiment', scientists say
"Black carbon from satellite launches has about 540 times bigger climate effect than black carbon released by ships, cars and power plants."

There's currently four of these LEO satellite "megaconstellations" in progress:
Amazon Leo: 3,236 sats
Qianfan: 15,000 sats
Guowang: 13,000 sats
Starlink: 12,000-34,400 sats.

The speed with which the astronomy community set up working groups and organized special discussion sessions around satellite megaconstellations (compared with often glacial pace for these things) demonstrates very clearly that astronomers are Not Fine With This. 🔭
In one of my astrophoto groups, a guy posted a photo that shows some non-celestial stuff in it and someone said it’s satellite constellations and another person said that astronomers really hate those and several men have weighed in to say actually astronomers think they’re fine

Satellite megaconstellations will threaten space-based astronomy - Nature
Rapidly growing satellite constellations pose a substantial threat to astronomical observations, with projections indicating that future space telescopes will have more than 96% of their exposures affected by satellite trails, necessitating urgent mitigation strategies.

The Outer Space Treaty, like all treaties, is based around the state, even though it also says that the use of space is the common province of humanity. States eg US are issuing launch licences for spacecraft constellations that harm all humanity. Other nations don't get a say.

Falling satellites released 17 metric tons of aluminum oxide into the atmosphere in 2022, per USC research. Full buildout of megaconstellations could push that to 360 tons yearly, a 646 percent increase over natural levels. Viasat petitioned the FCC for an environmental review. None has followed.

But other states don't have to issue licenses to operate for the megaconstellations. So far they have all acquiesced. Australia, for example, licenses Starlink through the Australian Communications and Media Authority. Collective state action is needed. 🧪 🔭 🛰️
