As with a lot of things, it isn't the initial outlay, it's the maintenance costs. Terrestrial datacenters have parts fail and get replaced all the time. The mass analysis given here -- which appears quite good, at first glance -- doesn't including any mass, energy, or thermal system numbers for the infrastructure you would need to have to replace failed components.
As a first cut, this would require:
- an autonomous rendezvous and docking system
- a fully railed robotic system, e.g. some sort of robotic manipulator that can move along rails and reach every card in every server in the system, which usually means a system of relatively stiff rails running throughout the interior of the plant
- CPU, power, comms, and cooling to support the above
- importantly, the ability of the robotic servicing system toto replace itself. In other words, it would need to be at least two fault tolerant -- which usually means dual wound motors, redundant gears, redundant harness, redundant power, comms, and compute. Alternately, two or more independent robotic systems that are capable of not only replacing cards but also of replacing each other.
- ongoing ground support staff to deal with failures
The mass analysis also doesn't appear to include the massive number of heat pipes you would need to transfer the heat from the chips to the radiators. For an orbiting datacenter, that would probably be the single biggest mass allocation.

Did Microsoft do any of that with their submersible tests?
My feeling is that, a bit like starlink, you would just deprecate failed hardware, rather than bother with all the moving parts to replace faulty ram.

I suspect they'd stop at automatic rendezvous & docking. Use some sort of cradle system that holds heat fins, power, etc that boxes of racks would slot into. Once they fail just pop em out and let em burn up. Someone else will figure out the landing bit

Why does it need to be robots?
On Earth we have skeleton crews maintain large datacenters. If the cost of mass to orbit is 100x cheaper, it’s not that absurd to have an on-call rotation of humans to maintain the space datacenter and install parts shipped on space FedEx or whatever we have in the future.

Putting a datacenter in space is one of the worst ideas I've heard in a while.
Reliable energy? Possible, but difficult -- need plenty of batteries
Cooling? Very difficult. Where does the heat transfer to?
Latency? Highly variable.
Equipment upgrades and maintenance? Impossible.
Radiation shielding? Not free.
Decommissioning? Potentially dangerous!
Orbital maintenance? Gotta install engines on your datacenter and keep them fueled.
There's no upside, it's only downsides as far as I can tell.

We’re probably thinking of it the wrong way. Instead of a single datacenter it’s more likely we build constellations and then change the way we write software.
There will probably be a lot more edge computing in the future. 20 years ago engineers scoffed at the idea of deploying code into a dozen regions (If you didn’t have a massive datacenter footprint) but now startups do it casually like it’s no big deal. Space infrastructure will probably have some parallels.

There's nothing paradoxical about it. There's no such thing as a temperature gradient in a vacuum, there's nothing to hold or measure temperature against. And thus a vacuum is a really good insulator. Which is why a vacuum flask, which ultimately became one of Thermos' most well known products, is used to control temperature both in and outside the lab.

mandevil · 6h ago
International space law (starting with the Outer Space Treaty of 1967) says that nations are responsible for all spacecraft they launch, no matter whether the government or a non-governmental group launches them. So a server farm launched by a Danish company is governed by Danish law just the same as if they were on the ground- and exposed to the same ability to put someone into jail if they don't comply with a legal warrant etc.
This is true even if your company moves the actual launching to, say, a platform in international waters- you (either a corporation or an individual) are still regulated by your home country, and that country is responsible for your actions and has full enforcement rights over you. There is no area beyond legal control, space is not a magic "free from the government" area.

That is not how international law works, you don't get to say "we are a new country and therefore not bound by treaties that earlier forms did."
This principle was established when Nazis were convicted for war crimes at Nuremburg for violating treaties that their predecessor state the Weimar Republic signed, even after the Nazi's repudiated those treaties and claimed they were signed by an illegitimate state, and that they were a new Reich, not like the Wiemar Republic.
Basically if territory changes hand to an existing state that state will obviously still have obligations, and if a new state is formed, then generally it is assumed to still carry the obligations of the previous state. There is no "one weird trick" to avoid international law. I assure you that the diplomats and lawyers 80 years ago thought of these possibilities. They saw what resulted from the Soviet and Nazi mutual POW slaughters, and set up international law so no one could ignore it.

If you read the Starcloud whitepaper[1], it claims that massive batteries aren't needed because the satellites would be placed in a dawn-dusk sun-synchronous orbit. Except for occasional lunar eclipses, the solar panels would be in constant sunlight.
The whitepaper also says that they're targeting use cases that don't require low latency or high availability. In short: AI model training and other big offline tasks.
For maintenance, they plan to have a modular architecture that allows upgrading and/or replacing failed/obsolete servers. If launch costs are low enough to allow for launching a datacenter into space, they'll be low enough to allow for launching replacement modules.
All satellites launched from the US are required to have a decommissioning plan and a debris assessment report. In other words: the government must be satisfied that they won't create orbital debris or create a hazard on the ground. Since these satellites would be very large, they'll almost certainly need thrusters that allow them to avoid potential collisions and deorbit in a controlled manner.
Whether or not their business is viable depends on the future cost of launches and the future cost of batteries. If batteries get really cheap, it will be economically feasible to have an off-the-grid datacenter on the ground. There's not much point in launching a datacenter into space if you can power it on the ground 24/7 with solar + batteries. If cost to orbit per kg plummets and the price of batteries remains high, they'll have a chance. If not, they're sunk.
I think they'll most likely fail, but their business could be very lucrative if they succeed. I wouldn't invest, but I can see why some people would.

Yes, and also just because a space data center isn’t useful today doesn’t mean it won’t be required tomorrow. When all the computing is between the ground and some nearby satellites, of course the tradeoffs won’t be worth it.
But what about when we’re making multi-year journeys to Mars and we need a relay network of “space data centers” talking to each other, caching content, etc?

It's super reliable, provided you've got the stored energy for the reliable periods of downtime (or a sun synchronous orbit).

Technically, the datacenter company could be found liable but not for traffic, only for take-down refusals. Physical security is the most important security.

I missed there batteries for the half the time being in the Earth shadow (as originally i calculated that for crypto where you can have half the time off which isn't the case for the regular datacenter) and panels to charge them, that adds 10kg for 1 KWH, and thus it will get down to about 5000 GPU for the same weight and launch cost.
Paradoxically the datacenter in LEO is cheaper than on the ground, and have bunch of other benefits like for example physical security.

We may as well get ahead of the problems we’ll face and solve them in a low-stakes environment now, rather than waiting to discover some novel failure scenario when we’re nearing Mars…
If starcloud integrated with something like starlink, using the laser inter satellite links to distribute ground comms across a network of satellites, then the datacenter maintaining a direct link to a base station is probably a non-issue for most purposes.
For your other concerns, the risks are worth it for customers because of the main reward: No laws or governments in space! Technically, the datacenter company could be found liable but not for traffic, only for take-down refusals. Physical security is the most important security. For a lot of potential clients, simply making sure human access to the device is difficult is worth data-loss,latency and reliability issues.
- lots of cheap power - deploy 100s of ASICs, let each of them fail as they go

But does work if I rotate phone to landscape mode.
Paradoxically the datacenter in LEO is cheaper than on the ground, and have bunch of other benefits like for example physical security.

It's a crowded field, you have to do something to stand out!
