Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

Ukrainian surface drones had Starlink comms disabled on direct Musk's orders (web.archive.org)

of course he was afraid of russian nuukes. this only prompted Ukrainian engineers to bypass use of starlink entirely and current sea drones, like the one used in second Kerch bridge strike, or these used against SIG tanker and Olenegorsky Gornyak landing ship use domestic technology only

Can't go to Mars if your massive satellite constellation (plus competitors) results in enough space junk to make reaching orbit difficult.

Starlink causing a Kessler event and grounding all spaceflight would be delicious irony, but I believe their orbits are too low for this to be a problem. Instead they just annoy astronomers and Russians.

On the other hand, Kessler wrote: "Some of the most environmentally dangerous activities in space include large constellations such as those initially proposed by the Strategic Defense Initiative in the mid-1980s"

SDI's Brilliant Pebbles originally proposed a 10,000 unit LEO constellation.

Starlink is already close to 5,000, and Musk wants 30,000. Add in the Chinese effort estimated at ~13,000. OneWeb has 500-600 up there.

Ugh apparently it won't stop Starships from fucking off to Mars

https://en.wikipedia.org/wiki/Kessler_syndrome#Implications

However, even a catastrophic Kessler scenario at LEO would pose minimal risk for launches continuing past LEO, or satellites travelling at medium Earth orbit (MEO) or geosynchronous orbit (GEO).

OTOH the faster Musk fucks off the better so ...

"would pose minimal risk for launches continuing past LEO"

I suppose so, and yet you could say the same about aircraft flying over the launch site on launch day. A collision is unlikely due to the speed of the rocket and the short time it would be at aircraft altitudes.

But I'm pretty sure they still don't want anyone flying over the launch pad.

@gerikson

Even if it doesn't rapidly degenerate into a full-blown Kessler Event, I'd have to think there'd be enough going on there to increase uncertainty and risk.

That’s what the flamethrowers are for.
