10,000 Starlink satellites orbiting the Earth?? I didn't know there were so many, really so many. Their presence has already radically transformed the orbital environment. There are so many that in 2025 alone they performed around 300,000 collision avoidance maneuvers. In short: on the one hand, they're convenient for us because of their fantastic internet connection, but on the other, they're generating truly unprec…

Kessler syndrome doesn’t apply at that low altitude.

It wasn't easy at all. Nobody except SpaceX could have done it at the time. This is the result of SpaceX being able to launch much cheaper than anyone before them, and being able to use these high-cadence launches to both implement and test incremental improvements in their rockets and streamline their reuse of preflown boosters. SpaceX was the only conceivable launch provider for this, and if it had been an external…

And phased-array antennae. The network would be next to useless if each receiver needed to track the satellite physically.

Beamforming is an old technology though. It's not hard to do, just a pain to do cheaply when you've got a bajillion emitters unless you have custom silicon.

Imagine a threat actor blowing up one or two of them. Or malfunction leading to collision with a launcher. Or any satellite malfunction and failure to de-orbit in time. Remember MAD, mutual assured distraction? Well we created another one for access to space

Space is big. Really, really big.

Even with 10,000 satellites, any one satellite is probably going to be 100 miles away from the next nearest satellite.

And so what if they collide? This isn’t Kessler syndrome territory, it’s low enough orbit that debris would re-enter and burn up rapidly. You’d lose the colliding satellites, and that’s likely all. Not that there has been a single starlink collision, but y’know.

Wait until multiple, non-coordinated copy-cat constellations are sent up there ...

Large operators like SpaceX and OneWeb do coordinate with each other. Ground based radar tracking data from the government is also made available to operators, and SpaceX has developed their own optical space-based detection system (Stargaze) which makes data available to other operators as well.

There's a lot of money in this stuff, lot's of planning. It's being managed by competent people who give a shit.

You shouldn't be worried about it, these satellites are in Low Earth Orbits that readily decay if the satellites don't regularly reboost themselves using their electric thrusters. And performing collision avoidance maneuvers is just part of how they're designed to work. Note that its 300,000 avoidances, not collisions. These are more like ballerinas than careening billiard balls.

It's an LLM spambot, it is incapable of worrying. I'm much more worried about another instance of nobody noticing what they're replying to.

Can I ask how you're so certain? The first two sentences reads human-typed to me.

No no their profile says “software dev.”

Software decentralized evolved version ?

The russians threatened that if they were not given access to starlink? And china has musk by the balls via tesla.. at this level states treat cooperations like servants for everyone including threatening to beat them mercilessly.

What I found so fascinating about starling is how easy it was for a single country, even a single company in this case, to pollute near-earth space. I understand the mechanics of LEO, and the de-orbit mechanics put in place. But the world-wide impact, unknown side-effects on the upper layers of atmosphere on the re-entry of literally thousands of satellites within fairly short period of time?

On a bad year, there might be a few hundred tons of Starlink satellites reentering the atmosphere. In the same year, there will be something like 5000 tons of meteors reentrying, and if you include space dust that radars don't see, you're looking at a few times more than that. This appeal to scary ignorance to poop on a technology is a cynical reflex. Instead of just saying that a bare number with no context scares y…

They are 0.8 ton each and last ~5 years. 10,000 / 5 * 0.8 = 1,600 tons per year at 10k satellites, and their goal of 40k satellites would put it well above the amount of asteroid debris impacting each year. Further asteroids contain very different materials and don’t all impact at the very low angles you see from de-orbiting in satellites. Thus, I don’t think you can presume this is meaningless without actually modeling it.

Space dust on the other hand behaves very differently on reentry because of the high surface area to volume ratio.

E.g. gowinston.ai gives 98% probability that the comment is human written. LLM detectors of course aren't always correct, but generally their detection performance for pure LLM text can be high (accuracy % in high 90s).

Do you have some specific techniques or strategies for LLM text detection? Have you validated them?
