@angelastella
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.
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.

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 Horrible!

@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 @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 -

We must make sure that what comes down does not go back up. No Starlinks! I wonder if they are still shooting them up there. My guess is yes. We have to stop this Monster Musk in every way possible. -
@albertcardona @sundogplanets Also have an animated version
@spottyfox @albertcardona @sundogplanets
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.)

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

@nixzhu Good luck inventing that.

@sundogplanets
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."
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." -

It makes me think of a recent proposal for terraforming mars by introducing tiny amounts of aluminium to the atmosphere.

#JohnBrunner with Eptification - with a bad result - and #JoeHaldeman with some sort of overlays in #WorldsApart and assorted authors with "memory tapes and of course #TheMatrix "now I do!"And in a less friendly way #LarryNiven with #Corpsicles and #RichardMorgan with the #DigitallyStoredHumans and #DigitallyFreightedHumans and uploading into a sleeve.

Yes, shortcuts to make the most of limited bodies. But to keep a closed ecology plus the mechanical part of the habitat and some mining/manufacturing capability there's no easy substitute for those bodies, and I'm afraid the number needed is still higher than expected.

@sundogplanets @mastodonmigration Now imagine having a million data centers in orbit, from musk alone. Before long, every few seconds a satellite will come down – with all its payload burning into the atmosphere

@sundogplanets as I understand it, it’s even worse
These alloys don’t vanish, their chemical components mix with the air, they keep floating high up and they cause changes

@hansbot @mastodonmigration It's every 3 minutes for a million satellites with 5 year lifetimes

@hansbot @mastodonmigration It's every 3 minutes for a million satellites with 5 year lifetimes
@sundogplanets @mastodonmigration Yes. And it will likely not become a monopoly. Two competitors in the US, one in the EU, one in China, one in India, and it’s down to 2/min. To replace these, they would need a dozen or so launches per day, adding to the looming environmental disaster
