A former NASA engineer - now a Google Cloud AI infra alum - rips apart the idea of building GPU datacenters in orbit. His verdict: space is a terrible server rack. Power delivery? A nightmare. Heat dissipation? Worse in a vacuum. Radiation? Frying time.
Even a 200kW solar rig (think ISS-sized) could barely run 200 GPUs. For context, OpenAI's Norway datacenter is aiming for 100,000.
