That was a month ago. https://news.ycombinator.com/item?id=49830606 This is just a status update, which the title is pretty clear about.

Too many details might be bad for the stockmarket and its AI hype train...

A competing team at Google already exfiltrated the weights of the model running on the satellite and uploaded them to huggingface! https://huggingface.co/google/gemma-4-E4B

Satellite cooling is long figured out, the problem is that it requires a ton of expensive mass.

Radiation hardening is not a huge issue in LEO either. It is an issue, not the issue.

Overall, it's like choosing international flights as your choice of a restaurant. It's...fundamentally...doable...? But nobody knows why you would want that, unless flying GPUs is the point rather than to offer a competitive service using the server sats.

Someone made a good point on a previous comment like this: the main selling point is the public can’t destroy them

It is expensive, but the radiators won't necessarily push the state of the art. https://arstechnica.com/space/2026/07/how-hard-is-it-to-buil... The current test is to see how big an issue rad-hardness actually is.

Scott Manley has an excellent video breaking down the math on cooling.

It’s totally doable.

The fact that this comment is being downvoted says so much about so many things. And so many people. This community--not just HN, I'm talking about tech at large--has totally lost its way.

Could you provide a source for that claim?

Unlimited power and real estate with zero local opposition.

The entire concept of an illegal AI is something I hope never comes to pass.

Making it difficult to shut down AI’s is very important. There’s a real chance we end up with a regulatory capture cartel that’s enforced because of “safety”.

But there are solid engineering and logistical advantages. Not having to deal with nimby’s, permitting, data center blowback is a big advantage. It’s difficult to spin up new power infrastructure in western countries, and putting up a satellite with direct 24/7 solar power means you can skip the headache of building new power infrastructure. My electricity bill has increased by 50% in the last year and most of that increase is likely because of data centers powering AI. If we can instead directly power that compute in orbit from the sun then it will not increase demand on existing power infrastructure.

The standard motivation is 24/7 unfiltered sunlight to power the AI with, where you're not in anyone's backyard and don't need to convince a planning commission.

>The only thing anyone cares about is whether the (economic)math works on put AI in space.

This is a greater fool market. The only thing anyone cares about is whether they think someone else will believe the math will work out.
