The thing that people miss in this is that the feature they're seeking by putting servers in space is only to have servers outside of any jurisdiction, with the advantages that it might bring

[–] TheFinn@discuss.tchncs.de 8 points 1 day ago (1 children)

Whatever company owns it will be responsible for it. That company will answer to whoever it needs to here on earth.

[–] mad_djinn@lemmy.world 1 points 1 day ago

you think us sub-millionaires have any power in government, huh?

[–] REDACTED@infosec.pub 3 points 1 day ago

Imagine spending 10 years to build a server in space to avoid some law and next month government changes the law

[–] hansolo@lemmy.today 2 points 1 day ago

This is 1 million% what's at play here. Tech bros HATE that they have to deal with stupid laws, and putting a server outside of the jurisdiction of literally every country is a dream. A giant server ship has to dock, it needs fuel....not so with something in orbit (in Elon fantasy land anyway)

Well its a great ideal if you happen to be a company with a space program, sounds like a very lucrative venture.

[–] Paranoidfactoid@lemmy.world 4 points 1 day ago

Just tell Elmo to add bigger CPU and GPU fans. That'll work.

[–] jj4211@lemmy.world 24 points 1 day ago

Ridiculous, you can't have cloud computing in space, there's no atmosphere!

[–] itsblorpintime@lemmy.org 2 points 1 day ago

Whatever happened to resource efficiency, being able to do more for less energy? This whole thing is super unsustainable.

[–] Avicenna@programming.dev 50 points 2 days ago (3 children)

I don't think the point is to really build datacenters in space. The point is to convince investors that it can be done in a profitable manner so some people can create a fake businesses out of it and siphon money off the system. Much like the same as trying to convince investors that LLM + more money = AGI

Considering the ludicrous price to put each pound of equipment into orbit, I'd like to invite them to send as much hardware as they can in to (high) geostationary orbit so they can find out how well a vacuum does NOT promote radiating heat

Edit: also forgot about solar radiation flipping bits. I love the idea of them having to reboot the machine (if they even can) remotely once ever 15 minutes

[–] brownsugga@lemmy.world 38 points 2 days ago (1 children)

Don’t data-centers require massive cooling?

[–] ramenshaman@lemmy.world 20 points 2 days ago* (last edited 2 days ago) (10 children)

Yes, and it's easier to cool things on earth. In space, there's no air to help you cool thinks off, you can only reject heat through radiation. Most spacecraft are carefully designed to reflect heat/light on surfaces facing the sun and radiate heat into empty space from surfaces that are shaded.

Wouldn't it be cheaper to put it underground?

[–] AA5B@lemmy.world 4 points 1 day ago

In either case the installation cost and infrastructure costs are excessive and the I/o is probably limited

[–] Lucky_777@lemmy.world 1 points 1 day ago* (last edited 1 day ago) (1 children)

Also couldn't power it with the sun. Which is infinite and free power

[–] Tollana1234567@lemmy.today 1 points 1 day ago

still have to deal with space debris, and the radiation damaging/wearing down the equipement overtime.

[–] Prior_Industry@lemmy.world 16 points 2 days ago (1 children)

Mr Musk has to justify that 1.75t valuation somehow

There's another problem that nobody mentions. Putting thousands of additional satellites into space would seriously increase the risk of Kessler Syndrome occurring.

They're a great idea if you happen to own a company making AI, a company making rockets, and a company controlling public opinion.

My question is always how the hell are you going to cool them. Do you know hard it is to move heat in a vacuum?

[–] fallaciousBasis@lemmy.world 2 points 1 day ago

How would you power them?

The surface area of solar panels exceeds the surface area needed for radiators to cool everything.

In space I would imagine you'd find the perfect sandwich ratio. One bun solar, one bun radiators, the meat being the racks.

[–] EndOfLine@lemmy.world 90 points 3 days ago (3 children)

The problems; plural; is that the person who popularized the idea of data centers in space has little to zero understanding of any of the space sciences and yet owns and directs one of the world's largest, and privately owned, aerospace companies with massive government contracts that splits its time with their own AI work.

Have you never seen a movie set in space? Evrytime someone gets sucked into space they freeze. You saying every movie got it wrong?? Space is cold. Duh.

The idea of putting data centers in low Earth orbit sounds cool at first. It feels futuristic. It feels like something that should be efficient. It is not.

Yes, space is cold. Yes, you get a lot of solar power. Those are the two points everyone repeats. What they leave out is basic physics and cost.

Cooling in space is not free. There is no convection. Heat only leaves through radiation. That means giant radiator panels. AI racks throw off massive heat loads. The more compute you add, the more radiator surface area you need. That adds mass. Mass costs money to launch.

Even with companies like SpaceX driving launch prices down, it is still extremely expensive per kilogram. And servers are not permanent infrastructure. They get replaced every three to five years. You cannot economically upgrade racks in orbit the way you do in a building on Earth.

Then you have radiation. Either you harden the electronics, which makes them slower and more expensive, or you accept higher failure rates and build in heavy redundancy. Maintenance becomes a logistical nightmare. A failed power supply on Earth is a service call. In orbit it is a robotics problem.

Meanwhile hyperscalers like Amazon Web Services, Microsoft, and Google put data centers next to cheap power, fiber backbones, and cold climates. It is boring. It is practical. It works. Orbital data centers only make sense if we already have large scale industry in space. We do not.

And what really makes these threads irritating is the obvious rage bait framing. Throw up a clickbait title about AI destroying the planet or Big Tech trying to escape Earth and you attract people who already hate AI. The discussion stops being about engineering and economics and turns into ideological noise.

If someone wants to seriously debate energy efficiency or scaling limits, fine. But pretending near Earth orbit is some obvious solution is not serious analysis. It is a cool sci fi concept. It is not a rational infrastructure strategy.

Naive question, but would bit-flip also be a problem without the atmosphere to shield (some) radiation?

[–] ayyy@sh.itjust.works 16 points 2 days ago (1 children)

Thats not a naive question at all. You’re totally right. The term to learn about this is “rad-hardened computing”. It’s a solved problem, but the solution involves a buttload of redundancy and extra silicon with huge performance reductions compared to non-hardened tech.

It’s less of an issue if you’re in the shadow of the sun but still quite a big issue.

[–] DreamlandLividity@lemmy.world 8 points 2 days ago* (last edited 2 days ago) (1 children)

Yes but also no. Bit flips will happen unless you have rad-hardened computers but apparently, bit-flips are not really too problematic for LLM training. I guess when correct answers are optional, correct buts are as well.

There was one study where they set the price of launching at 0 and it's still a lot more expensive to use data centers in space.

[–] Voroxpete@sh.itjust.works 52 points 3 days ago (17 children)

For anyone who doesn't know, this is because space is an absolutely terrible place to put computers. Getting power is actually the easiest problem to solve, and is still really hard, because building any kind of infrastructure in space is hard. Then you've got all that radiation you have to shield against because you're no longer protected by the Earth's atmosphere, and worst of all you've got the cooling problem because Jesus fucking Christ, space is not cold!

This is why I get annoyed every time a scifi movie shows people freezing to death in space. Because it leads to this level of mass delusion and then suddenly it matters and everyone just unquestioningly believes the lie that space is cold. Space is a vacuum. A vacuum is what your Contigo travel mug uses to keep your coffee scalding hot after four hours. If vacuums are that good at keeping something hot when it naturally wants to get colder, think about what they'll do to something that is actively generating heat. All of your components are going to cook.

There are proposals to put data centres at the bottom of the ocean that are substantially more credible than this idiocy.

[–] Tollana1234567@lemmy.today 1 points 1 day ago (1 children)

seems the bottom of ocean equally stupid. in space you would have to deal with comsic/solar radiation damaging a satellite-type data center, and then you need solar cells/nuclear power, space debris is another problem.

a bottom of the ocean you would have to deal with the enormous pressures, even at several hundred feet down, corrosion, critters living or clogging up the 'buildings, silt.

[–] Voroxpete@sh.itjust.works 1 points 1 day ago

Yes, the bottom of the ocean is a terrible place to put a data centre. And the fact that it is, somehow, still a more practical option than space is a really good indicator of how unbelievably stupid the entire notion of space data centres is.
