You know both Russia and China are perfectly capable of targeting and destroying satellites, yes?

Neither could destroy SpaceX satellites as fast as they can be launched. No State can. The issue would be whether they could cause enough damage to make the orbital plane (temporarily) unusable.

Are those protected from EMP that can kill scores at once?

According to its Wikipedia entry, McMurdo Station had a 20Mbit/s satellite link so far. https://en.wikipedia.org/wiki/McMurdo_Station#Communications

I had a buddy [1] that worked in the kitchen at Amundsen-Scott South Pole Station for a few seasons in 2012-2014. From what he told me: The internet works at certain times of the day at different bandwidths depending on the satellite. I think at that time there was 3 in orbit, and one of them was a retired Navy sat that had like dial-up speed. Also everything that goes to the station stays there so the vinyl collecti…

> Also everything that goes to the station stays there

What's the reasoning behind that? Presumably people bring back clothes and other personal affects right?

How about getting Tesla banned from China and possibly starting an orbital war that triggers the Kessler syndrome?

What would be banned are the dishes. China doesn’t need to send a missile to LEO (which would be unnecessarily costly for them).

China wouldn't need anti-satellite weapons to punish Elon Musk, since he has business interests in China. Hence "ban Teslas".

Why wouldn't the Pentagon want to blanket China with US propaganda?

Sure, but how do you propose to "blanket" China with Starlink modems?

I'm sure there are plenty of ingenious smugglers in China.

Nobody is going to disclose & use anti-satellite technology over internet censorship. Hell, China isn't even aiming for bulletproof terrestrial censorship - they are happy with "good enough".

> Nobody is going to disclose & use anti-satellite technology over internet censorship.

This constellation is plausibly if not probably duel-use technology. You can bet that China is planning ways to disable it if war breaks out.

Does this mean they've figured out satellite-to-satellite data transfer?

Yup, I think that's the implication of the "space laser network". The plan for Starlink has been to have laser crosslinks between the satellites to provide coverage in places where the satellites can't directly see a ground station.

That's the plan, but it's an unimaginably difficult task. Many have speculated they wouldn't be able to pull it off at scale.

The point of Starship is to launch hundreds at once, several times a week if it goes as planned (that's a few years away.) Forget Mars colonization, the only practical use for such a booster is to fight a war in LEO.
