How about providing free internet to China and Russia, to give the people there proper information without government oversight?
How about getting Tesla banned from China and possibly starting an orbital war that triggers the Kessler syndrome?
Does this mean they've figured out satellite-to-satellite data transfer?
This is the first mention of it working that I've seen. I wonder if it's a limited deployment for Antarctica or the beginning of a large rollout.
Earlier quoted context omitted.
I'd imagine the latency and per-installation cost is quite high.
It looks like it operates at 35,000 km and relays the signal between the base and Australia. The ping time seems to average a hair under 250ms. https://www.satellite-calculations.com/Satellite/170HourList... http://bhs.smokeping.ovh.net/smokeping?target=APAC.AS7474-1 Starlink satellites are mostly in the 550km elevation range. Average pings seem to be in the 50ms range, but this would be single satellite performance.…
That would be impressive, as that would be 140,000km in 250ms, or about twice the speed of light
Most satellite IP I use starts at about 650ms

That's not even mentioning the sanctions on Western technology entering Russia at the moment.

You think the USG that funded SpaceX/Starlink isn't going to have control over it...? While Starlink was marketed as a boon to rural democratic internet access, those promises have been walked back and its pretty clear that it the limited bandwidth is primarily intended to increase the Pentagon/ICs communications capabilities in the field, much like the Internet itself. The USG did not fund a swarm of satellites so t…

According to its Wikipedia entry, McMurdo Station had a 20Mbit/s satellite link so far. https://en.wikipedia.org/wiki/McMurdo_Station#Communications
Also everything that goes to the station stays there so the vinyl collection is amazing, and they have a huge Betamax / VHS library and most importantly they have /The Thing/ on Betamax.

Edit: Here's the satellite schedule for this week, https://www.usap.gov/technology/documents/SPSAT%2020220915.p... and you can sign up for a listserv of updates here: https://www.usap.gov/technology/1935/
These are the available birds in orbit for Antarctica:
Broadband: South Pole TDRSS Relay (SPTR) Satellite
Broadband: Defense Satellite Communications System (DSCS)
Broadband: Skynet Satellite Communications System
Narrowband: Iridium Multi-Channel System (IMCS)

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.
