A scary quick calculation: there are 10,375 Starlink satellites in orbit https://planet4589.org/space/con/conlist.html, all coming down within 5 years.
That's an *average* of 5 or 6 a day for the next 5 years. And the v2's are bigger than the v1's. v2's are (conservatively) 1000kg and (conservatively) half aluminum. That's 2.5-3 tonnes of aluminum per day. 8 times the natural infall rate of aluminum (and there's lots of other scary things like lithium). What will that do to our atmosphere?
SpaceX is awful.
@sundogplanets As a Chinese citizen, I hope to one day use Starlink to bypass the GFW and access the open Internet. SpaceX is doing amazing work!

@nixzhu I'm sorry that's what you are forced to depend on. Enjoy it before SpaceX starts Kessler Syndrome, I guess?

Had the idea it involved an ablation cascade aka Kessel syndrome.

Of a rather larger initial mass!
The Moon. -
Interview 2 went much better (which is good, Saskatoon is where it's most likely that pieces would be found, if there are any pieces) and I remembered to say the email address I want people to send possible space junk finds to! AND I got a better camera setup and actually brushed my hair. But I'm somehow going to end up on CBC national news in my ratty farm sweatshirt AGAIN aren't I?
@sundogplanets IDK I feel like the ratty farm sweatshirt helps your message feel authentic
"I came to Saskatchewan to raise goats and watch stars BUT THESE JERKS STARTED DROPPING STUFF" is compelling

But you don't need anything in low earth orbit ( #LEO ) for that.
Arthur C Clarke originally pointed out that 3 satellites in the geostationary orbit could provide up, down, and sideways, communication for the whole planet surface.You probably want a shorter delay and a lower power budget for your relay than that, but I submit that you do not need to reduce either to the levels LEO allows. Something between GEO and LEO would work nicely and be easier to track for comms.

unintended terraforming?
"Scientists are eager to understand how these particles of aerospace debris interact with other aerosols in the stratosphere because of anticipated increases in space traffic and their potential impact on the ozone layer. They also want to explore the impact of possible future proposals to seed the stratosphere with millions of tons of sulfur aerosols to slow the rate of global warming by reflecting sunlight back to space."

It is really quite good.Separately, one of the discussions I've seen in #SciFi is of the minimum size of society for prolonged survival in Space.

@sundogplanets Also, every piece of aluminum that they burn or drop in the ocean is aluminum that could be used for other things.
A very productive mine in Australia is closing because it's run out of ore. Copper mines are extracting ever larger amounts of rock to get smaller specks of copper sulphate.
There's no thought for the future. -

Large.I remember a good discussion about that topic on Charles Stross' weblog. If the idea is having modern industry, it could run to millions.

@nixzhu @sundogplanets We just need heavy industry in orbit so that the potential and kinetic energy of those satellites can be recycled.

That's the one.
Various scifi authors have introduced ideas - rather deus ex machina ones - to reduce the number of bodies required to hold thouse skills and functions.
I suppose now YouTube etc is a bit of a start -

Apparently Bradbury was very popular in the Eastern Bloc. There's also a live-action Soviet Martian Chronicles. (And a bunch more. Low-budget not-very-good F 451, decent Veldt, etc.)

@sundogplanets If the Kessler Syndrome actually triggers, we’ll just have to launch a fleet of specialized 'cleaner satellites' to clear the debris field and restore the orbit.

https://research.noaa.gov/noaa-scientists-link-exotic-metal-particles-in-the-upper-atmosphere-to-rockets-satellites/Yeah that uh... sulfur aerosols idea was clearly thought up by people who said "I saw The Matrix, and that version of the future looked just so much fun for humans to live in."
