Stop imagining, in 2021 a cluster of computers were sent up to test this, and since then several instruments are in the works to make use of similar (but not same) CPU clusters. As always, finding a system that is affordable and radiation tolerant is the problem.
Do you have a link to this?
Full disclaimer I had some code of mine and a paper that I'm not linking.

That's one hell of a stretch, you're essentially suggesting that the average New Yorker wouldn't be just as up in arms as much of rural America if a Chinese style sham democracy was instituted in the US.
Willingness to get vaccines and wear masks made New Yorkers look Chinese. Honestly I think when human population centers get dense and connected enough they are essentially the same. Economic ties and shared needs and values are ultimately more significant than the 6% of the population in government (e.g., Chinese CCP). The CCP is on their way out anyway and not a true threat.
CCP on the other hand isn’t going anywhere.
There were some comments yesterday on tracking subs, talking about the throughput requirements. It made me think about another bit of orbital infrastructure: in-orbit inference engines on satellites, so processing on vast gobs of data can happen without beaming the reams of data down. But yeah, seems like interoperable space protocols are starting up. BACN-Mesh works. Maybe not quite so important & I forget the name…
The European Space Agency has already demonstrated on-the-edge processing with Phi-Sat-1. They use AI to detect clouds and only downlink images below a certain cloud cover threshold. https://en.wikipedia.org/wiki/Phi-Sat-1
So, is this cubesat 99% thermal control radiators or what?

> If they used it to block, sure. Starlink’s advantage is SpaceX’s margin. As long as Starlink competitors use SpaceX to reach orbit, the advantage is realized on both Starlink launches (as savings) AND on competitors’ launches (as profit). Doesn’t that make SpaceX’s advantage 2x their margin?
> the advantage is realized on both Starlink launches (as savings) AND on competitors’ launches (as profit). Doesn’t that make SpaceX’s advantage 2x their margin? Sort of. Every dollar of competitors’ launch margin doesn’t go to Starlink. SpaceX’s near-infinite fundraising capacity, and thus low cost of capital, is far more significant. (There are also orbital trade-offs between imaging and comms.)
I have to wonder how sustainable this is. From the perspective of an investor, I would not be excited by Tesla being down 70% off peak and Twitter becoming the most notable corporate clusterfuck of the year. Investing in SpaceX these days seems like a bet that the CEO will be so distracted by his other problems that he won't have time to mess with the people actually running it.

With what sounds like the industry moving to something more like high throughput real time mapping, does that mean that there's a chance we'll see an open source imagery dataset/tile server sometime afterwards, when the current dated offerings become less competitive?

> fishing vessels in the Pacific Ocean This is the dorm delivery idea for space businesses. Everyone is working on it, including folks with no commercial ambitions, and the number of people willing to pay for it is small, and they’re cheap.
Yes and no. These island nations are pretty small and poor, so obviously Fiji or Vanuatu aren't going to be paying for it. Instead, what I would expect is that the US, Australia, and New Zealand would pay for it to maintain good graces with these nations. WRT geopolitics, this is a good stick for beating up on China as they're one of the main offenders in IUU.
Right. The business model is sympathy money from big governments. Practically, that means re-selling to a government contractor. A contractor for whom this is an afterthought, and who has a million other providers to choose from, some of whom don’t need to make money.

The countries being harmed by this are in no position to beat up on China. The ones who can don’t care about it enough to make it a diplomatic priority.

On the contrary: how does spending more than the next nine countries, all of which have totally unique geopolitical positions and defense needs, have anything whatsoever to do with what we need to spend to achieve our goals? It's like saying Walmart spends more on inventory than the next 9 retailers combined: Walmart has a totally different business than Nike and GAP. In fact it's even more asinine than that: it's li…
Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. The cost of one modern heavy bomber is this: a modern brick school in more than 30 citie…

Russia and China have been weponizing space for decades and they already have working hypersonic missiles.
You are offering a pretty narrow worldview here, and a blatant simplification of geopolitics. Ignoring the elephant USA in the room here who’s militarization dwarfs any competition, then escalation (or even answers in kind) is not the only option on the table. There is also international agreements. International agreements has proven much more effective as a grand strategy then escalation. The nuclear non-proliferat…
Like the Outer Space Treaty [1]?
