Starlink is now on all seven continents, enabled by its space laser network

So I could, if I live in Africa, buy it and send it to an address in Europe, go pick it up and then use it from my home in Africa?
But no, you would not be able to ship the user terminal to Africa and use it. You can’t even move it more than a few dozen miles from the address they have on file and keep using it, unless you have the more expensive license for mobile users (think RVs and boats and such). Even then it stops working if you enter an area where service is unavailable.
All they need is one dish installed on every continent for the 'all seven continents supported' to TECHNICALLY be correct, obviously this tweet is just marketing. It's still pretty cool to see that many incredibly under-served communities in South America/Africa/Asia will be able to be served considering running physical infrastructure is very expensive.
Without coverage, no one can use Starlink.
If there is coverage, state governments can allow Starlink usage.
Seems a bit like false marketing to say "Starlink is now on all seven continents" when it's more like "Starlink has satellites over seven continents but you can only actually use it on five of them"
Those countries' poor radio engineers...
Which isn't to say that they would operate those systems (or starlink) in peacetime without the approval of the host country, just that they can use those systems at any time... While I don't know for a fact that SpaceX has left the decision on where to use starlink up to them, I'm pretty sure that would be the case.
> Which isn't to say that they would operate those systems (or starlink) in peacetime without the approval of the host country
To the original point, Starlink wouldn't be claiming that "Starlink is now on all seven continents" unless somebody (e.g. the USAF) was at least conducting connectivity tests in these countries, if not putting Starlink into active use — which would, again, be much to the chagrin of local RF engineers, who had.
Elon's history of marketing says otherwise.
They have coverage over all seven continents because of that and I have very little doubt that it's been tested in those continents as well. "Availability" here seems to be a proxy for "is technically solved" vs. "is commercially available".
If you're asking "what's the difference?" Think about the war in Ukraine. Starlink wasn't (and isn't?) commercially available there but was able to be deployed in an emergency.
I think it’s for the worse if governments disapprove the use of Starlink. Starlink should at least be allowed to send out an SOS message. It could save a life out on the frontier.
Seriously, wtf? Look at some orbits. Satellites do not sit stationary over one location, except the ones called "geosynchronous satellites".
Edit: if Starlink is not available in a country it is for one of three reasons:-
- the country is not at the top of Starlink's priority list for connection (commercial reasons)
- the country wants nothing to do with anything based in the USA (politics)
- the country has an obstructive bureaucracy (corruption, stupidity).
Antarctica. Thank you for this.
Non-commercial users such as the US military are using it on bases, ships, and aircraft worldwide. Antarctica is notably a continent without US military bases, so the "on all seven continents" claim was not complete until these scientists got a hold of a dish.
Would be a bit like saying McDonalds is on all seven continents since mcdonalds.com is reachable on all seven continents, but then you cannot actually order McDonalds at Antarctica so it smells a bit like misleading marketing.

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. This should drop as more units are brought online and increase capacity. Also, the laser interconnects are theoretically faster than terrestrial fiber, so there are expected to be many long-hauls where starlink will be the fastest option.
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
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)
What's the reasoning behind that? Presumably people bring back clothes and other personal affects right?
Absolute speeds or relative to each other speeds?
Though they could, if they needed to, only connect to the satellites flying at low relative speed.
It would sometimes reduce latency if they're able to though.
They've got a 'pez dispenser' already worked out too for starship, just need to light that candle now. Ramped up testing again last week so I'm hoping it'll be soon (said that 12 months ago)

Turns out this challenge involves a 200F sauna, so 200F air, not water.
Edit: I don't know if these two participated but I knew them from the NJIT CSTR. Some of the smartest people I met who were basically volunteering just so they could get flown down every year: https://youtu.be/ciqAZSoOmr8?t=676. Gil was just getting through some back surgery at this point, was in massive pain, and still flew out that year if memory serves me correct.
That is some real deal holyfield physics and math knowledge right there.
…Availability on all continents might be a requirement to qualify as a provider for satellite emergency services like the one Apple will soon offer with iPhone 14 Pro

First one the satellites were evenly spaced, sometimes 1-2 were 'missing' and I could see between gap in the clouds maybe 7-8 at the same time. Altogether maybe 30.
Second time, the spacing wasnt even but there were at least 60 of them till the show finished.
Of course real number could be much higher since I noticed them ranfomly when looking up. Their line was perfectly aligned and they were going fast (probably close to Earth).
I guess this is how satellite launches look these days, but never saw more than 1 satellite at the same time in the same trajectory on the sky, and then this. Very futuristic experience.
:)
Sorry. The inner child in me got far too excited by this.
Edit: a link that goes over some of this https://www.spacex.com/updates/#sustainability
However, for starlink specifically aren’t the satellites all low enough to deorbit and burn up automatically within 5 years? This should eliminate the orbital debris problem for this constellation specifically.
A different problem is what happens with all the burnt up aluminum and other metals in the high atmosphere. I saw a post mentioning this once recently but also don’t know much about the scale or effects of this problem.
Chatted once on a Webex with Chris Hadfield about 6-12 months ago, who said that the service was somewhat better and more reliable than his current satellite connection, but also that it wasn't necessarily good enough for a change in mindset. He knew that sometimes he wouldn't have good enough connection for video calls out there, and that was ok by him.
I don't think he was thinking about the space dust / negative externalities
I find no Google results that are appropriate for "Starlink satellite retrieval"
The Starlink website notes "95% of "all components of this design will quickly burn in Earth's atmosphere at the end of each satellite's lifecycle".
It's amazing that it's already looking like this: https://satellitemap.space/
And of course, it's not black and white. Took me a bit longer... had to remember that Corporate Social Responsibility departments exist, but in February 2022 SpaceX put out a statement at least: https://www.spacex.com/updates/
Funny - so they've done a reasonable amount of work to minimize space junk, which is great! Absolutely no mention of helping out astronomers with the line of sight problem.
A beta product isn't perfect, more news at 11.
SpaceX has extensively worked with astronomers, including having a working group that meets weekly, presenting at conferences, doing multiple iterations of design changes and so on.
Moreover, sending satellites to space is really inefficient. It wastes a lot of energy and pollutes a lot. To increase coverage, the amount of satellite they'll need will be more and more. And the skies will become more and more full of space junk (each satellite lives for 7 years).
I think there are other solutions. But of course, other solutions do not favour Elon Musk as much.
How a single man can be responsible to so much nuisance to the rest of humanity...
A few satellites orbiting use far fewer materials to provide coverage of the entire planet than doing so terrestrially would.
As Starlink satellites age out they de-orbit. No space junk.
You’re welcome to propose & implement better solutions. Until then, this is the very best humans can do to lift all of humanity with minimal environmental impact.
Until Starlink, the fastest speed they could get from Verizon (the only provider they have access to) was maybe 4 to 5Mbps. And it was still capped at 20GiB a month. Starlink gets them 60 to 70Mbps during overcast/rainy days and 100 to 120Mbps on sunny days with no cap.
I know it isn't altruistic of Starlink to cover these areas, but at least they are. I can now see my parents via video chat multiple times a month vs. seeing them a couple of times a year.
Verizon, AT&T, T-Mobile, the cable providers, etc. just don't care about them. And rightfully so. They are an extremely small market. It annoys me how much money the US government has given to these ISPs in the hopes that they'll expand rural access, but they never do. Or they use the money to pay lobbyist to say "4g is fine for them"
Not the conventional definition of light pollution. The conventional definintion of light pollution is sky glow, which is not caused by satellites.
Further, the satellites are around 6th magnitude, which is below human eye visible, but certainly still problematic to astronomers.
> which is a disaster for astronomers.
A "disaster" is overstating it. Take a look at this study for example https://www.caltech.edu/about/news/palomar-survey-instrument...
> "There is a small chance that we would miss an asteroid or another event hidden behind a satellite streak, but compared to the impact of weather, such as a cloudy sky, these are rather small effects for ZTF."
.
> Moreover, sending satellites to space is really inefficient. It wastes a lot of energy and pollutes a lot.
Space launch is a miniscule portion of global emissions and there is no reasonable way it would seriously contribute to global emissions going forward. Further, as the fuel costs are such a small portion of launch costs, it would be easy enough to produce the fuel via direct carbon capture and have it still be economic, which is a path forward in the future.
> To increase coverage, the amount of satellite they'll need will be more and more.
The goal is never to serve high density areas. It's to serve areas that are functionally impossible to serve any other way without massive government subsidy.
> And the skies will become more and more full of space junk (each satellite lives for 7 years).
You've misheard. Those satellites don't stay in orbit very long as their orbits are so low. They'll deorbit within a few years, even if completely lost, but normally they'll de-orbit automatically at the end of life, producing no debris.
So there still seems to be some restraint around the concept of shooting down foreign satellites. I guess it's a "mutual assured destruction" type situation: once you shoot down a satellite, you'd better be prepared to lose your own.

On the other hand, providing free media merely to subvert the people of main land China could be seen as a company over stepping it's bounds by far.
I will bet China would sanction anyone who dealt with Starlink.
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.
But more to your point I agree; they won't try to destroy the constellation itself over something as petty as a few people using Starlink to circumvent their 'Great Firewall'. People sufficiently motivated to get around the firewall already can, without the need for Starlink. The CCP doesn't seem to care about it; the firewall doesn't need to be perfectly airtight to control the population, it only needs to be 'good enough'. And they wouldn't want to expose any new anti-satellite weapons they have, particularly soft-kill weapons that might be addressed after discovery with a software patch.
The issue would be whether they could cause enough damage to make the orbital plane (temporarily) unusable.
The probably is there for a reason though, the exact extent of their capabilities is unclear.
Here's a citation: https://thediplomat.com/2022/06/chinas-directed-energy-weapo...
I would not call it rumors. If you'd like a more authoritative citation, here is a DIA (Defense Intelligence Agency, i.e. US military) report cited in the article I cited above: https://www.dia.mil/Portals/110/Documents/News/Military_Powe...
> During the past two decades, Chinese defense research has proposed the development of several reversible and nonreversible counterspace DEWs for reversible dazzling of electro-optical sensors and even potentially destroying satellite components. China has multiple ground-based laser weapons of varying power levels to disrupt, degrade, or damage satellites that include a current limited capability to employ laser systems against satellite sensors. By the mid- to late-2020s, China may field higher power systems that extend the threat to the structures of nonoptical satellites.
The discussion of current capabilities is primarily about optical satellites (though it can be read to include other components), but it probably applies to giant sensitive phased array antennas too.
I also think that both countries could launch geosync satellites or using existing geosync satellites to just generate a shitton of noise on whatever spectrum Starlink would use.
Starlink of course won't get a license for spectrum in either country.
This would be an act of war and open their birds to retaliatory strikes. Tracking down the receivers and levying draconian punishments on those caught would do the trick. Moreover, from the example of Chinese students abroad, it's unclear access to information would do much.
Not by the thousands, short of taking ALL satellites out.
Kessler syndrome takes care of them all once you generate enough space junk.
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 that American (nor Russian, nor Chinese) farmers can watch Netflix.
That's not even mentioning the sanctions on Western technology entering Russia at the moment.
As well as VPNs existing, international sim cards also 'bypass' internet filtering. Absolute restriction of the internet is not the goal. The goal is to not allow anything approaching a critical mass to do so, especially less technically literate who would not seek out VPNs etc unless they were marketed to or directly facilitated. The next is to all but remove the browser, email is truly dead having never been a big thing socially, with a domestic app orientated landscape; mobile penetration is far beyond lap/desktop.
This doesn't make it better, but it is how it is.
Incidentally, HN is blocked in China. Am using a VPN.
I was just implying that I'm guessing getting actual Starlink hardware through legit channels is probably not something that will be available.
What's the end-to-end level of starlink vis-a-vis encryption? I have to imagine it's pretty good.
I'm sure the backdoor master key "everyone" is pushing for would find a practical use in this situation
The government would restrict or ban import or sale of the hardware. They'd make them illegal and use possession of one as a reason to throw the owner in jail.

Either Starlink is the Transport Layer of NDSA, or it proves that SpaceX has the technical ability to create the Transport Layer (no other company does.)
The mesh network aspect of NDSA / Starlink is new insofar as they've now figured out how to do what they wanted to do back then.
Space-based interceptors are missing from NDSA as it's described in public. But all the technical challenges have been resolved, what remains is the political challenge. Since the space-based interceptors are the politically contentious part, if they were going to do this it would make sense for them to build the 'benign' parts first while not talking about the rest.
