Orbital data centers are a good idea if one wants to get massive golden parachutes that siphon money from all the investor cash that the entirely u realistic promises brings in. They are a grift that will most likely benefit Musk in the same way all his other pie int he sky bullshit does.
Being technically terrible hasn’t really stopped that from happening with his other bullshit projects.
It’s literally just taking the piss out of idiotic investors. Data Centers, AI, space, new frontier, new markets. It checks all the boxes to get idiots excited to dump money into your tech company so people keep talking about it because talking about it is what gets results. Hopefully nobody is dumb enough to actually try it, it’s an absolute scam.
I see it as a win-win.
Either Elom and his fellow dipshits waste a ton of cash chasing literal pie in the sky,
Or
A viable commercial presence in space is validated and terrestrial power needs eased.
/S
Can you all not even tell this or sarcasm?
I see it as a win-win.
Except when they put up about 70x new satellites then what we currently have up there, and cause a cascade of collisions that results in nothing being able to enter orbit (including humans travelling to space).
We’re at 14k satellites.
100k is the cascade failure limit.
Space X is proposing one million satellites.
Edit: my “70x” figure is very fuzzy just-woke-up early morning math. No guarantees.
Edit 2: dang! One million divided by 14k is 71.428! I almost nailed it.
No, you don’t get it. (Good job on the math though, btw)
Every AI gets to have one, huge Moonraker sized LLM space station. Grok Station 1, Gemini Geosynchronous, Claude Comet. Whatever. But all eggs in one huge solar-powered basket each.
Staffed by 1 or 2 humans each. Required. By law. Armed people. Because, of course they should have guns in space.
Then just see what happens. I bet it would be amazing.
Anybody Who Thinks Orbital Data Centers are a Good Idea
Is Suffering from AI Psychosis, Experts ArgueDoesn’t Understand Basic PhysicsTwo 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.
Love the idiot in the article comments saying „the heat is immediately removed into the vacuum of space“. What is the thermal conductivity of a vacuum, genius?
Are we talking about a vacuum of copper or a vacuum of feathers
And yet the IPO of SpaceX was justified with the presumed future success of its space-based data center program.
Wait is that really a thing
Yes. He unironically promised to build data centers in space. So basically, his company’s stock went up, because he falsely advertised something that is practically impossible to achieve at this time.
Shits gonna be like 99% radiator
One consumer grade graphics card surrounded by the largest heatsink ever produced.
“That ought to do the trick!” 😆
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.
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.
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.
I suspect Musk is trying to ensure his satellites are up before anyone else’s, so when the inevitable legislation is enacted to control who launches what, he already “owns” the lion’s share of “orbital real estate”.
They’re not going to put up these satellites, because they won’t be close to usable or affordable. Either the workloads will be miniscule, or the cost to put them into orbit is prohibitive.
The whole pitch was a cool sounding “space age” solution to a problem with AI datacentres that everyone is aware of. It was just a snakeoil salesman’s promise just so he could con investors out of money for his sweet 1.7 trillion.
