    The “good idea” isn’t the data centers but the stock pumping. You propose something insanely difficult and expensive (also hopelessly impractical and stupid in this case) and because it is so difficult and expensive you claim you can monopolize the market if you succeed which is the ultimate dream of every capitalist but you just need some insane amount of investment to get there. Then when the money runs out you go back and ask for more and exploit sunk cost fallacy. All the while valuations increasing. It is an amazing way for already rich scammers to get much, much richer than could happen in a sane economy and slurp up huge amounts of capital that otherwise could have gone into more productive endeavors.

    Obviously in any well regulated economic system this shit would be subject to some proper oversight to protect the interests of the majority, particularly all the people whose pensions and livelihoods are at risk when this all goes to shit.

      isnt thats what all the tech conferences are for, to hype the investors up. how long can they keep up with the peddling on those conferences? everytime a new con is our hub , its almost always a different usage of AI, so they need to come up with new “ideas” each time.

      Two main problems with data centers. Power and cooling. In space the power is doable. The cooling is a major pain in the ass and always has been. There are only three ways to get rid of heat. Conduction, convection, and radiation. The first two don’t work because of the vacuum thing. The third is horribly inefficient. Just look at the ISS and the giant fins that only dumps about 70 kW of waste heat through radiator “wings” that weigh several tons. A single rack in a high density compute rack can generate 100kW by itself.

      So yeah given the expensive and how inefficient it is, it’s a terrible idea.

      Edit: I’m a system architect so dealing with data center heat is something I’m familiar with.

        There’s also the very real problem of data transfer.

        On land you just lay down another fiber optic cable and you can double your data transfer rate.

        In space, you have to deal with cross talk and interference on a limited spectrum.

            Not really, because it can’t be solved, just worked around.

            Lasers are still subject to the inverse square law, but with a slightly different multiplier.

            Also, lasers still have the bandwidth issue of not being able to double up the communication lines due to cross talk and other fun physics issues.

            There’s a reason why fiber will never go out of style.

            If it was a solved problem it would be widely used, but it isn’t. Ever looked at the reports of starlink speeds? It’s not reliable at all, everything other than a fully clear sky with cold weather (meaning less moisture and particles in the air) affects the communication. It physically can’t be a good or better alternative to fiber (or anything else that isn’t wireless).

        Basically they’d need about as much in radiator fin surface area as they would have in solar panel area. The ISS has 8 solar array wings, 35m x 12m, that can produce about 30 kW each, or 240 kW total, in sunlight (which is only half the time). The ISS has a complex cooling system, but relies on 4 radiators about 3.1 m x 13.6 m to reject up to 14 kW of heat each (56 kW total) for cooling the solar arrays themselves. The main cooling system uses 6 radiators, each 23.3 m x 3.4 m, to reject 70 kW of heat (from this report it sounds like each radiator may be capable of rejecting more than 1/6 of the heat but that the system as a whole needs to be kept under 70 kW of heat rejection).

        So that seems like about 650 square meters of radiators can provide about 120 kW of heat rejection.

        Today, a 72-GPU Blackwell server is 130 kW in a single server rack. The next generation rolling out now has 72 Rubin GPUs in a 230 kW server, in a single rack. And that’s not even a “data center.” That’s just a single (albeit very powerful) server. How many can you string together, with networking equipment beaming data connections back down to the ground, before the ratio of solar panels and radiators to the actual ship size becomes unworkable?

        That said, it’s technically possible, especially if you can radiate the heat at higher temperatures than the ISS does, as the Stefan-Boltzmann law shows that the hotter the radiator, the more heat it can reject. Just completely infeasible from an engineering and economical standpoint, for any data center that hopes to be relevant in an age of 100+ MW data centers.

          All they’re sending up is 1 server rack. 125kw avg, 150kw peak.

          Radiator needs to be ~twice as big as ISS, but we probably have improved their efficiency in recent years so maybe not twice?

    It’s such a hilariously dumb idea I hope the tech bros sink millions into it.

    Lets make a data center we can’t maintain, upgrade or access for any practical reason. Waiting for the suggestions to put them in geostationary orbits so that way their latency is even higher but going to struggle staying powered when in Earth’s shadow. Or get put in the Earth-Sun L1 so they always have solar power but now have to have significant more radiators on top of even MORE latency beyond beyond the moon’s orbit.

      People don’t understand just how difficult it is to cool stuff in space. Half of the shit sticking out of the ISS that people think are solar panels are actually radiant cooling systems, and the ISS will generate WAY less heat per volume than a data center.

          Beyond the power requirements for the computer, there is also the power that will be needed to transmit back to earth.

      This whole idea reminds me of the “putting solar panels on highways” idea that keeps popping up from time to time. Anyone who has ever built anything understands how stupid it is. Even if you could do it, it still wouldn’t make sense over just putting solar panels next to highways.

      There is an unsolvable compute problem. The average PC on earth has multiple bit-flips a year from cosmic rays. The space hardened chips we use are 50nm and the chips used from inference are 4 to 6nm. 50nm is far more cosmic ray resistant than 6nm because of the transistor size. Are we supposed to think making H100s with a 65nm process is possible? The speed of light creates a die size limitation as well.

            They are not using 6nm process chips in the ISS. The computers themselves were made before that process existed. An off-the-shelf space hardened computer system uses 65nm process. Cosmic rays is a very general term, it covers basically everything that flies around in space, that includes sources like the sun, which is hammering everything in the solar system with rays. Outside of the atomsphere there are so many more cosmic rays that non-space hardened computers can not even make calculations. Combined with the difference between the bit flip rate when you make transistors 10 x smaller is also fucked up high. One CPU cycle will have enough erros to make the computer useless. It’s a multi-faceted problem and when the largest limiting factor is weight & size, it can’t be solved with scaling.

        The way I see it is they are doing inference, not transfiring bank account balances. I’d be curious to see some actual experimental data, but I’d expect LLMs to skip past bit flips same way you shrug and move on from spelling errors. At worst you can do your critical calculation in triplicate on your 6nm nodes (with redo upon dissensus) and reduce your bit error from 4/year (or 4000/year or whatever have you in orbit) to (4/year)^3

          A bit flip might change a 0 to a 1 or a 1 to an infinity. Even if you could just do everything three times, that triples the hardware and energy costs compared to terrestrial computing.

          I don’t think you don’t understand the difference between the amout of cosmic rays, which are basically any flying particle, on Earth compared to space. Small nodes would be dealing with multiple per cpu cycle. Multiple could be 1 million a second, I am trying to figure out a way to measure. It would be something like distance from atomsphere(rate of total particles) x probably of an object the size of a transitior getting hit(rate of collions). I could probably find the bit-flip rate for an off-the-shelf space resistant chip and infere the rate for the size I need, but there are other factors. A bit will not flip on every collision, shrinking transistors exponentially increases this.

      I agree, that this is at the moment not a viable thing and especially the SpaceX “concept” is complete bullshit.

      I do not agree with some of your points, since they are solved/irrelevant (e.g. “regular maintenance”, “low latency”) or could be overcome with reasonable tech advances (e.g. “rockets prohibitively expensive”, “radiation shielding”).

      Let me steelman the argument a bit with this single bit of - sadly forgotten - “super cool and innovative tech”: “Underwater data center”, like project Natick (Microsoft) or the Chinese project:

      https://www.datacenterdynamics.com/en/news/chinas-hicloud-launches-wind-powered-underwater-data-center-targets-500mw-subsea-deployment/

      Soooooo, if we will ever see something other than our current land based data centers, we will see millions of ocean data centers, before we will ever see a single commercial space data center.

      Reasons:

      • Delivery is super cheap (in comparison to space) at scale, thanks to the already existing wind farm infrastructure
      • Weight is not an issue
      • Cooling is solved
      • Maintenance is not necessary, but replacement is. Easy on scale, because modular.
      • No radiation shielding necessary
      • Connection: data cable = no extra lag or quantity limit

      Oh, and by the way, it is still not clear if even ocean data center will be viable. Just found this 😂

      getting large datacenter level quantities of data from earth into space and back, and at low latency, is no triviality.

      Latency is a huge issue, but so is bandwidth.

      Land based data centers will have multiple hundred gig (and faster) fiber connections to the outside world.

      Replicating that level of bandwidth on wireless links to a satellite in any sort of stable way is (as you said) no triviality. I would even classify it as near impossible.

          The $200/kg launch price target is based on 150 ton capacity. That’s a $30m launch costs target. Volume/foldability matters the most because that is the actual constraint that limits datacenter launch to a single NVL72 size.

            Projected cost targets from SpaceX, especially for Starship are only losely related to reality. Weight is what determines the minimal required energy input to lift something into orbit. Independently from SpaceX number magic. Volume, like I said, can be an additional bottleneck but never undo the above.

              most of the fuel weight required is to lift the rest of the fuel. Fuel costs is about $1m for full load. Rest of cost is huge staff, maintenance, and capital cost of rocket.

          Starship is huge. I dont know how tightly they can fold these expected dishes, but by weight, they can amd will do 60 starlink v3, and itd be 50 datacenter dishes equivalent. How many they can actually launch is going to depend on how well the solar and radiator folds down, so it might be a volume issue vs weight where they cant launch with the max weight capabilities of the ship.

      The datacenters are only a little bigger than a v3 starlink. It’s 1 rack of compute, around 125kw avg 150kw peak. The biggest part is the solar array.

        If it’s one rack it’s kinda pointless? And also absurdly more expensive than putting that one rack almost anywhere else in the world. And you can’t really fix or upgrade it. And then it’s in space and more susceptible to bit flips.

        I’m not sure there’s a single thing it being in space does that’s better than it not being in space.

          They want to put a million of these up there long term, where are you going to find space for a million individual racks? Now it’s a large datacenter again.

          I did see one thing about a company adding a cluster or something to someones house and giving them a cut of it. That decentralizes the power distribution, and space requirement, but it adds other problems like vandalism / theft as how well can you protect a thing tacked onto the side of a house worth 10s of thousands of dollars.

          Edit: And you don’t fix or upgrade them, they deorbit in ~5 years, and get replaced with the next best thing. Radation protection to avoid bit flipping will be a cost issue, but they already have hardened chips that work in space, so I’m not sure how much new technology is needed, and starship can lift a shit ton of weight, so heavy shielding is possibly an extra option?

          Edit2: Just to be clear, I’m not trying to say they are going to earn enough revenue to make these things profitable like they did with Starlink, I’m just talking about the technical specs of what they say they’re going to do. There’s a lot of misconceptions about what they even intend to try putting up there.

            Large data centres are used for a reason, it’s way more efficient to shove all the compute in one large building than putting it in space, at all.

            Its a horrifically stupid idea, with no real benefit at absurd cost.

              It’s not no real benefit, these are some, which are legitimate benefits.

              • Unlimited sun, without the sun having to go through the atmosphere which increases the efficiency of the solar panel.
              • No opposition / red tape from communities fighting against the data centers, some communities are evening banning them.
              • No theft or vandalism.

              Just to restate my relevant edit you probably didn’t see above

                You can get more power from solar on the ground, cheaper, because it isn’t in space and they’ll get deorbited which is worse than vandalism because the entire thing is now gone.

                I’m not disagreeing and saying they won’t do it, I’m just saying it’s an incredibly stupid idea.

                  That just increases the land space required though which makes it harder to get it built upfront, but I agree, land based solar, even taking 3x+ the land required + battery backup is probably still cheaper given they’ll last 20 years or more.

                  Ground projects like that take years to complete as well, between finding a spot, permitting, building it etc and to some extent time is money in this current environment.

                  Weight wise, they can launch 50 AI datacenters per launch with Starships 100T capacity, but volumetric wise I don’t know how well they can fold these up and if they’ll actually reach 50, but lets say they can get 50. I honestly have no idea if they can.

                  That’s 7.5MW of solar panels deployed each launch which will be coming off a factory line launching multiple times a week. They did 123 starlink launches in 2025, so thats 922.5MW solar capacity launched in a year if they did that with the AI sats, but they’ll likely do way more if starship actually works.

                  You can’t build an almost 1GW solar array (edit and datacenter) on land that quickly. (edit2: Oops I didn’t do the 3x+ for the 1GW solar i mentioned above, it would need to be 4-5GW on land so it can overproduce to store enough in the batteries for overnight)

                  The downside of course is it’s only going to last 5-10 years. That’s a lot of costs to try to recoup in that time frame.

      This is what I’ve been tearing my hair out over any time this comes up. If you put a computer in space it will heat up until it achieves incandescence. Which is bad for the performance.

        I don’t have a good grasp on what technology exists for space, but I would assume that radiators of some sort would be possible. Not in the conventional way that they ineract with a medium to release heat, but instead that the radiators emit heated particles - kind of in the same way that water evaporates without boiling. With that being said, I have no idea what efficiency that would operate under, and I have no idea if such a radiator would be used up fast. It sounds like a terrible idea, but I don’t posess the facts.

        Some people don’t believe in space travel because there is no air to push against in the way that jet engines work. But they fail to understand that space travel operates under other ways to generate force. I just don’t want to end up in the same sort of argument as them, believing that it’s not possible to cool down machines in space just because there is no medium for conventional cooling.

          For an intro to real proven methods you can look up how the cooling for the ISS works. It’s quite interesting, but takes a lot of space, for relatively little power.

            Exactly. That was my assumption. I just think it’s unfortunate that the arguments rely on that conventional cooling wont work rather than pointing out that the existing alternatives are very inefficient.

          So is the plan is to use a heat-pump to cool the computers while getting some waste-product as hot as possible, and then eject the waste product? Or perhaps rather than ejecting it, the heat could be put into a large surface-area heat-sink thing to just radiate the energy black-body-style…

          I think ideas like this are fair and reasonable if we have to have a data centre in space (for example, if we wanted people to live indefinitely on a space-colony or something like that). But its pretty clear that no plan will ever be anywhere near as good as what we can do on the planet’s surface.

          Building and operating these things on the Earth’s surface is already expensive and resource intensive. And doing it in space is going to be a lot worse.

            I agree. I just saw that the comments were only considering conventional heat dispertion to a surrounding medium and that it wouldn’t work in space. I feel it would be counterproductive to base the arguments on that narrow idea, but much more productive to realize that there are alternatives, but the current alternatives are much worse.

    If and only if someone is insane enough to develop off-planet manufacturing with the bulk of the raw materials originating from somewhere in deep space, e.g. asteroid mining, putting data centers in space might be useful for problems that demand intensive compute and can work with extreme latency.

    Then again that’s like saying inventing the airplane would have been a good strategy for Neanderthals to find better firewood.

          Self landing rockets were practically impossible not that long ago. Self driving cars were practically impossible not that long ago.

          There’s nothing fundamentally impossible about orbital data centres. The main factor against it is the $/kg of payload into space. That’s one of the many issues SpaceX is working to solve, and there’s nothing to suggest they won’t get there.

            Completely different level of difficulty.

            And be pedantic self-driving cars are not a solved problem. If you try driving a Tesla in autopilot and don’t intervene when it makes mistakes you’ll be in a wall within about 2 minutes.

            Building data centres in space isn’t just a technical problem, although it’s a major technical problem, it’s also an economic problem. Obviously yes it’s physically possible to do it but there’s no way of building a data centre in space for anything close to the price of just doing it on earth and with no other obvious advantage to it being in space there’s no reason to do it.

            It’s the same reason we don’t build a transatlantic railroad tunnel. Obviously it’s technically possible it’s just a very long tunnel, but it would be hella expensive.

            Other people have already explained the topic in sufficient detail, so I’ll just leave a quote from a former NASA engineer and a link to their article.

            Taking the NVIDIA H200 as a reference, the per-GPU-device power requirements are on the order of 0.7kW per chip. These won’t work on their own, and power conversion isn’t 100% efficient, so in practice 1kW per GPU might be a better baseline. A huge, ISS-sized, array could therefore power roughly 200 GPUs. This sounds like a lot, but lets keep some perspective: OpenAI’s upcoming Norway datacenter is intending to house 100,000 GPUs, probably each more power hungry than the H200. To equal this capacity, you’d need to launch 500 ISS-sized satellites. In contrast, a single server rack (as sold by NVIDIA preconfigured) will house 72 GPUs, so each monster satellite is only equivalent to roughly three racks.

            Source: Datacenters in space are a terrible, horrible, no good idea.

                  It’s rational because the payload cost is coming down and down and down with SpaceX. Reusable rockets was a massive step.

                  Once it’s affordable, why wouldn’t they do it?

            Self landing rockets were practically impossible not that long ago

            Technically, they still are.

            Self driving cars were practically impossible not that long ago.

            There have been implementations of a sell-driving vehicle since the 1980s, and we’re still far away from “true” full self diving.

            Both of these examples demonstrate the adage of “the first 90% of the work takes 10% of the effort, and the last 10% work takes 90% of the effort”.

            The main factor against it is the $/kg of payload into space.

            Oh my lord no. Although, technically yes but not for the reason you think.

            The number one issue is heat dissipation. To radiate the heat from one DC satellite (at the power levels needed to run AI workloads) would need a football sized dissipation array. Even if Space X can invent some magical new physics and cut that down to a quarter of that size (hint: they can’t), we’re still talking about an order of magnitude increase in payload per satellite.

            Next on the list is volume. We’re currently at around 14k man-made objects in low earth orbit. As it is, satellites (including the ISS) have to perform collision avoidance maneuvers every so often. The calculated limit of satellites we can put up to low earth orbit before orbital collision maneuvers start to become unmanageable is 100k. Basically after that amount we enter into a state where several corrections for each satellite are made regularly, and a single collision at the 100k limit would result in a cascading series of collisions that will render low earth orbit impossible to use. Basically after that anything you put up will get shredded by the insane amounts of debris.

            Space X wants to put up a MILLION massive satellites that will require extremely large structures to dissipate the heat from the very power hungry AI chips.

            They fully know the impossibility, and when challenged about the over crowding issue during an interview, an engineer brushed it off as “it’s not a problem”. People who speak that way about science and engineering issues are not serious people.

            That’s one of the many issues SpaceX is working to solve, and there’s nothing to suggest they won’t get there.

            There are countless engineering and physics reasons why they won’t. Stop sniffing Elon’s farts. They’re not good for your brain.

            Edit: all of this is to say: space datacentres are the dumbest idea yet to come out of that idiots face hole. And he’s said a lot of really really dumb things.

              So like you said, I’m correct. The only issue with thermal radiation is $/kg of payload. Again, this is an issue that they’re working to solve via methods like reusable rockets.

            The limiting factor for space data centers is absolutely not the cost to build them. The AI industry has already proven that they will burn the GDP of a small country just to have an LLM that shits out slightly better text that has coin flip level odds of being true.

            The limiting factor here is one of thermodynamics. A travel mug for coffee works because it has a near vacuum between the inner lining and the outer shell. Vacuums are fantastic insulation because there’s no atoms there to transfer heat away. Very useful if you want hot coffee for a few hours. Space is a big vacuum, and data centers are giant heat generators. You’re basically putting a computer in a perfect insulation medium. It’s really stupid.

    For the cost of one orbital data centre you could probably build 10 terrestrial data centres, bribe literally everyone involved in the contrustion to pretend that they built it in space, buy an island, fake your death, and spend the rest of your life off grid.

      There’d be nothing less than gold plated B300s in a space datacenter. If they’re spending billions flying it up there, they’re not going to be putting mid-range consumer GPUs in there. The gold plating probably doesn’t even do anything for radiation shielding, the AI just told them to add it to help prop up the AI bubble.
