I have to update the Starlink numbers in my talk.

I have to update the Starlink numbers in my talk. But this time, I last gave my talk TWO DAYS AGO. This is stupid.
There are 27 more Starlinks in orbit today than there were on Monday: there are now 9,526 Starlink satellites orbiting above our heads.
1,458 have already been burned up in the atmosphere (and at least 1 of those made it to the ground in the easiest place in the world to find space debris...) adding many hundreds of tons of weird metals to the stratosphere. #ProfSamLectureTour
Oh fuck, there are 9 more Xingwang megaconstellation satellites in orbit compared to Monday as well. Time to go outside (and not see any stars. I am really tired of cities).

@sundogplanets “This Starlink satellite crashed in the easiest place in the world to find space debris. Is that near your house?”

@sundogplanets cape canaveral hit their record for launches last year. i believe it was 109. i used to work down there, and starlinks were going up every week or so.

@sundogplanets So what are your proposed solutions and alternatives? Are you lucky enough to live in an area without light pollution? (regardless of satellites)

@sundogplanets correct me if I’m wrong, but isn’t this https://arxiv.org/pdf/2512.09643 kind of saying that we have at most 11 years (another solar maximum cycle) to basically have 100% probability of a Kessler syndrome more or less locking us from accessing LEO (at least with humans aboard) … and screwing up astronoy for years AND dumping bunch of interesting stuff into the upper layers of atmosphere? If yes - Why The F”&£ we are still allowing any mega-constellations and not downing the ones in orbit?

Here is thought experiment, which might make you incredibly depressed if being any more depressed in this day and age as possible: these satellites have a definite lifetime, and there is some expectation that some of them will become damaged and fall from orbit.
Injection of satellites means a consequential and maybe exponential death rates. That’s just basic demographics.

@sundogplanets I've just read that they are aiming for at least 12K (potentially 34K) satellites, with an average lifetime of 5-7 years.
Sorry if this question has been answered elsewhere already, but... is there any information about what 2,000 downed satellites each year will do to our atmosphere, exactly?

@sundogplanets I saw a really bright red shooting star trailing sparks two nights ago when I went out to look for auroras, and wondered if it were a dissolving satellite
it was traveling south to north in the sky east of my house in coastal Oregon

I can only manage a day in a city... and I used to live in London! (I loved it.) Now, give me nature and the countryside, any day

I've heard 40,000.

@deedeeque That's even worse! I got the 34K from https://en.wikipedia.org/wiki/Starlink

@sundogplanets and then there's TeraWave, which is Jeff's high bandwidth space based 5k+ LEO, 18 MEO constellation which starts launching next year.
They just keep on banging 'em up there

@sundogplanets
is there a map? -

@sundogplanets scene in a netflix scifi movie: why are the stars following me? Those arent stars those are drones and satepites...run!!!

is anyone quantifying/studying the possible effects/persistance/deposition specifics of the injection of vaporized metals etc in the atmosphere from de-orbiting starlink satellites (and others) ?
Is this ~15% attrition rate on these starlink satellites expected to be a sustained rate over the life of the program? If so... cumulatively, this could become quite significant over time. I do hope it's being looked at.

@sundogplanets Blue Origin announced TeraWave today.

@GhostOnTheHalfShell @sundogplanets this sounds like a business opportunity - satellite safety and recycling co. #darkhumor

@sundogplanets Keep fighting the good fight, Professor. We need someone to give us accurate information we can rely on.
