> The Satellite Constellations 2 (SATCON2) workshop was held virtually 12–16 July 2021 to discuss how to implement the mitigation strategies that emerged from SATCON1 to minimize the negative impacts of satellite constellations on astronomy and the night sky.

I started paying attention to orbiting light pollution thanks to Mastodon posts from #SamLawler @sundogplanets

I forgot the link for the first quote in this thread, just carry on:
> Elon Musk's SpaceX aerospace company has already launched close to 2,000 satellites, and plans to launch 42,000 satellites by mid-2027, with the goal of increasing access to broadband internet.
> That's nearly 10 times as many satellites than are currently in orbit, according to Lawler. Amazon is also making a push to build a rivalling satellite network.

Planned launch of thousands of satellites could obliterate our view of night skies, says astronomy prof | CBC News

Humans have long turned to the night sky to see natural patterns, but the University of Regina’s Sam Lawler fears the planned launch of satellites like SpaceX’s StarLink will obliterate views of the stars.

> #SamLawler.. at the University of Regina, says the darkness that astronomers and stargazers rely on is becoming harder to find due to the increase in "very reflective" satellites.. sent into low orbit.
> ".. light pollution from satellites is global -- there's nowhere that you can get away from it," Lawler told CTV.. on Friday.

This is why astronomers are warning about losing the night sky

Experts are warning that there appears to be nowhere left on Earth where astronomers can view the stars and planets without light pollution caused by low orbit satellites.

> Besides light pollution, the authors of the paper note that the launch of these satellites contributes to atmospheric pollution, both on launch and re-entry, and increase the risk of more satellite collisions in space.
> Political solutions or legislation will come too slowly to create regulation on the number of satellites in space or their brightness, said #Lawler.
