@mastodonmigration @sundogplanets Better that the garbage isn't at orbits where it would hang around much longer.
Indeed, at the current Starlink orbit it will all come down within 25 years. They want to start using higher orbits which will never come down.
Mastodon Migration (@mastodonmigration@mastodon.online)
Orbital Madness! You might be aware of the billionaires crazy Data Centers In Space, and Prof. Sam Lawler's @sundogplanets@mastodon.social efforts to save the planet from these lunatics. Just want to focus on one issue that should scare the heck out of everyone. Orbits above 1000km do not naturally come down. Starlinks orbit at 550km so debris deorbits within 25 years. They want to put these monstrosities in orbits up to 1800 km. A Kessler Syndrome event up there is forever! Madness! https://mastodon.online/@mastodonmigration/116407343907282036

Wholeheartedly agree with David. It’s your expertise that matters, and no ratty sweatshirt is going to detract from that.
@KimberlyN @DavidM_yeg @sundogplanets Yup. It's the old riddle about the two barbers. The harried-looking one? That's the one doing all the work.

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 the plus side is you won’t look like a slick PR shill.

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.

@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

@nixzhu
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.

@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."

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.)

I suppose now YouTube etc is a bit of a startSharing practical knowledge is a must. And it's the kind of thing we already do, not like molecular nanotechnology enabling cornucopia machines, or either versatile robots, or something else.
