Worst part of updating my talk: looking up how fucking many more Starlink satellites there were than last time I gave a version of this talk. 200 more than a month ago. Fuck.
There are now 6,209 Starlinks in orbit, fully 62% of the 10,009 active satellites in orbit.
All of these "fully demisable" Starlinks are planned to burn up and deposit their metal in Earth's atmosphere. I just saw multiple 100-pound pieces of another SpaceX "fully demisable" rocket, so I'm sure it'll be just fine.
