I'm excited I think of the Cowboy Bebop episode (Jamming With Edward) where they hunt down a rogue satellite to get data off it.

Also think it would be crazy to have a worm spread across the servers/starlink, would there be an antivirus system onboard or maybe not applicable, says RTOS can get a virus

> At ABI Research, where I work as an aerospace analyst, we did a rough total-cost-of-ownership comparison between a data center on Earth and one in space. It showed that the cost to launch and run a GPU in space for a year is at least an order of magnitude higher than the same feat in a terrestrial data center.

Economics calculator for Orbital vs Terrestrial Data Centers

You can play around with the cost sliders to estimate the economics, but even being quite optimistic, space data centers cost ~2-3x of their terrestrial counterparts.

Just so that nobody jumps in with what I first wanted to jump in with, this estimate was done with the assumption that Elon Musk's Starship is built, works as advertised, and launch costs are at the lower end of the projected range.

It wasn't an order of magnitude more because of how expensive rocket launches currently are.

(I'm glad that I read the article before arguing this one...)

Tyranny of the rocket equation[0] makes it hard for me to conceive how an orbital data centre could ever make sense.

If you just want to escape permitting laws, why not float it in international waters? That's a much more accessible and hospitable environment than LEO.

Honestly, data centers in the ocean make so much more sense than data centers in space it's kind of silly, but Mr Moneybags owns a rocket company he's trying to pump and dump, not a submarine company, so here we are.

I know Microsoft tried it. They had a press release saying it was successful but never did it again. Does anyone know more about that? I agree with you that data centers in the ocean seem a better bet.
