Prof. Sam LawlerIt's a Good Cloud Day. But the goats are very annoyed there was a teeny tiny bit of rain (they really do not like rain).
And now time for my morning radio interview. At least I had time for (most of) a cup of tea first.
hahaha oh no I forgot I was supposed to be on Google Meets for this interview not a phone call! Luckily my computer cooperated and the producer was very understanding. I just am wearing a ratty farm sweatshirt and didn't brush my hair and have a messy room in the background. Oops. Luckily I've got another interview for Saskatoon in 15 minutes so I can try to do better this time...
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?
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.
NIX@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!

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.
