None of that has anything to do with what I wrote, cool.

Smart choice to deflect. See you on the next Elon article you crave.

I mean there's not that much I can do when you just write unrelated stuff? "None of those people were connected to the Internet before" .. so therefore it's somehow good that those people's Internet access is controlled by one ass? "Businesses still need trucks" .. so therefore it's good to sell in slightly more efficient cars as the solution to the personal transport part of the climate crisis? Or to derail high speed rail projects with vapourware promises?

The things I wrote and the things you responded with aren't connected, so there's not much intelligent commentary to give.

What does that have to do with the odds of rocket induced dropped packets?

Any rocket induced dropped packets will just be resent after the rocket has passed or will be routed over other links. Lets not forget about clouds, birds, airplanes, hot hair balloons and tons of other things that separate the ground from space. We have protocols and networks already designed today that deal with this exact problem.

I don’t think there are many birds, aeroplanes, nor hot air balloons in LEO? Are there?! (I doubt clouds too, but meteorological phenomena perhaps?)

Now you responded to each item, good. That's how a conversation works.

But going into each individual political talking point for the various subjects you brought up would be tiring.

I'm not going to dive into your misguided views when we can't even talk about the initial topic that giving internet to disconnected people is a good thing and not garbage.

Cool. Bye.

That doesn't seem right, why would they be bright?

They reflect sunlight for some period of the evening and morning, before the sun is shining where you are and illluminating the sky too much.

Between when the sun first disappears below the horizon and when (nearly) all its light disappears, i.e., the end of astronomical twilight when the Sun's center is 18 deg below the horizon, seems to be about 90 minutes.

It's been awhile, but I'm pretty sure I've seen these much later than that. I'm talking about lying in a sleeping bag, looking up at the amazing starfields of pitch-black wilderness nights (tip: never use a tent except in extremis - look what you're missing!).

I have absolutely no idea how that number relates to any comparable operation. Can anyone add a banana for scale?

If you've got a laptop with a terrabyte drive, it would be 42,000 full laptops worth of data.

If you have a laptop with a petabyte drive, it would be 42 full laptops worth of data!

I think the GP is saying that we already deal with these problems with downlinks, so accounting for similar problems on crosslinks is a known, and expected quantity.

Hate the guy all you want, but how do you expect literal space internet to be uninteresting to a forum of self-proclaimed hackers?

It's the intersection of space lasers and the internet, how could we not talk about it.

I’m waiting for two things:

1. Full-circumference world round-trip latency sat to sat (yes it has to go to ground to “count” but I just want to know what the number is)

2. Deployed LEO servers running with laser communication to the Starlink satellites. Preferably gaming or CDN since either is a great way to verifiably test the limits.
