My job is mostly worrying about cooling paths, maintenance, power, heat transfer, lifetime of GPUs, and high performance networks. NVIDIA partner. I can drive to the datacenter. This stuff BARELY works here on Earth. Especially thermal issues.
Looking forward to watching spacex defeat physics.
Starlink V3 bus already has to dispose of ~20kW of waste heat from the electronics - because RF amps aren't that great at what they do. That's a ~2020 server rack, in SPACE.
Going from that to a 2026 server rack is engineering, not magic.
