As it stands, most if not all institutional and journalistic research around this topic I would consider compromised because they’re in some way or another financially interested in this becoming the next big thing. Aravolta included. That’s why most articles will counter each hard constraint with a handful of hopeful speculations.
As for pure scientific analysis, like the Scott Manley one, they tend to entertain themselves too much with the physics and mathematics and forget the economics behind it all.
Take Google’s own paper (https://arxiv.org/pdf/2511.19468) that estimates that launch costs, just to roughly match data center energy costs on earth, would need to reach 200USD/kg, which requires a 10 fold cost reduction relative to the current launch costs of Falcon 9. And that is to launch a _disposable_ server into orbit, that will disintegrate after a few years and likely have hardware failures well before that.
And these servers are not anything like a “data center”, and they won’t run the applications that we are already scrambling to find demand in earth. No, these would theoretically run some ultra-niche, highly experimental workloads maybe for NASA or the military. That alone can’t possibly justify the investment, at least not for the retail investor that actually expects a positive ROI. Nevertheless the tech elite and their pet journalists are more than happy to sell this fantasy to the average people.
Hell, I’m still waiting for Project Natick to materialize, Microsoft’s data center on the ocean, which makes far, far more sense than data centers on frigging space. Still they didn’t manage to make that one work in any meaningful sense.
