I have to update the Starlink numbers in my talk.
-
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.
@kitkat_blue Here's one paper: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024GL109280

@thejacenallen HA!! I love this idea! Doing math in front of a lot of people is a recipe for disaster, but I love this
@sundogplanets oh yeah the math. No way. I would never attempt this myself.

So, "yearly excess of more than 640% above natural (meteorite contribution) levels" plus "a noticeable delay (~30 years) between the beginning of the injection process when orbiting bodies are decommissioned and the eventual ozone-depletion consequences in the stratosphere." seems to add up to a potential ticking time bomb for the ozone layer.
Other than saying "significant" they don't attempt to quantify the impact...i'd be curious as to what that might be.

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
Are you fucking kidding me?? I have to update the Starlink numbers AGAIN from YESTERDAY.
There are now 9,551 Starlink satellites in orbit. 25 more than yesterday. FUUUUUUCCCKKKK I am going to bed.

@sundogplanets Will future generations be able to see the stars? Can we decommission these satellites? Or are we turning the sky into another landfill?

@sundogplanets How are they doing this this fast? Are there like daily rocket launches and multi-satellite deployments per launch? I feel like this should be a way bigger deal?!

@sundogplanets @olivia thats a lot of rocket fuel

@joshsutphin @sundogplanets they do frequent launches from each coast that deploy about two dozen satellites.
You can see the upcoming/completed launches to get a sense for HOW frequent. All the ones that say “Starlink mission” https://www.spacex.com/launches

Uh, yes. Feel free to start bombing them. The USA sure isn't gonna.
