Wasn't that the plot of Seveneves?
Had the idea it involved an ablation cascade aka Kessel syndrome.

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.
What is known about how much will it mess up the ozone layer?

Can goats get wet? I learned about donkeys that they can't get wet, since they'll cool out too much. I would think that goats could take rain and just don't like it, true?
@knud @sundogplanets wow, colour me surprised. TIL about donkeys!

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?
️ I pay much closer attention to interviews with people who really do look like they’ve just stepped out of their lab or office or classroom or goat pen than sleek coiffed media ready talking heads.Thank you for the time to give to the public good!

@sundogplanets I like scientists in ratty farm shirts stepping out directly from life situations. I trust them more as if I have to question which company could have sponsored their expensive suit!
Und you will reach the farmers better who will be bombed with that waste! -

awesome, Humans invented yet another way to massively pollute the environment they depend on.
Aluminum rain, sweet

@sundogplanets Glass-half full: If Musk tires of SpaceX all that crap will be out of orbit in short order.

There is no glass half full, they are sending more of it up all the time. The entire trillion dollar SpaceX IPO is predicated on pumping this satellite sewage into LEO.

Wholeheartedly agree with David. It’s your expertise that matters, and no ratty sweatshirt is going to detract from that.

OK, so just like me
The donkey's I am visiting ~1/year go into their stable or under their roof when it starts raining. I really like them.
(I don't have any image available, sorry!)

@mastodonmigration @sundogplanets Better that the garbage isn't at orbits where it would hang around much longer.

@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

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