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.

That sounds like the Guoxing Aerospace / ADA Space “Three-Body Computing Constellation”, currently at 12 satellites (out of a planned 2,800).

The Chinese project involves a larger number of less powerful inference-only nodes for edge computing, compared to Starcloud's training-capable hyperscale data centers.
