I presented at the local planetary journal club this morning about the 3 articles I co-authored for The Conversation in the past weeks about the effects that one million satellites would have on the night sky, the atmosphere, and the orbital environment (spoiler alert: all very very bad)

https://theconversation.com/a-new-space-race-could-turn-our-atmosphere-into-a-crematorium-for-satellites-276366

https://theconversation.com/too-many-satellites-earths-orbit-is-on-track-for-a-catastrophe-but-we-can-stop-it-275430

And one on light pollution that I thought would get published today but might not be out until after the weekend.

A new space race could turn our atmosphere into a ‘crematorium for satellites’

Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

The Conversation
@sundogplanets Musk's 1 million AI sats is pretty much a ponsischeme like hyperloop.
@Luna don’t forget the tunnel thing and Department of Government Efficiency *sigh*
@Luna Yep. That would imply lots of weight to be put in orbit.
@sundogplanets I don't think it would be inaccurate to picture the world from Wall-E
@sundogplanets What commons has not been raped?

@sundogplanets

So many issues with satellite "pollution"

Teaching future generations there was never a Natural sky and night view

Un obstructed view of the heavens is a birth right for any creature on Earth - I mean that

Huge security risks of constellations if the Muskrat goes out of business

Huge security risks if Muskrat is hacked or there is significant ground operations disruption

Out of control constellations, impact risks

@sundogplanets
IMHO it is quite strange that an agency of just one country decides over the sky pollution of the entire world.
We should expand the area in which every country can decide what or who is allowed to fly over it to let's say 1000 miles or 1500 km. Within this range every country should be allowed to destroy every object flying there before this object can cause any harm or generate profit.

Of course the US agency FCC might decide about satellites flying over the USA only.

@sundogplanets I love the idea of a local planetary journal club, but I suspect that similar to Mr Universe Competition there will be one planet being over represented.
@sundogplanets
Thanks for all you do for us Sam. I heard you on CBC One a bit ago and read you all over the place.
Earth's low orbit is becoming cluttered with high-velocity space junk

Thousands of satellites are being launched into space at low Earth orbit, joining hundreds of thousands of pieces of space junk, and it's becoming a real problem.
