Curious to learn how they deal with bitflip from cosmic rays and cooling. I’m so convinced the idea of compute in space is absolute nonsense, but that will still be interesting to see how they try to tackle the various issues

You can see the white/silver radiators; they're large but not outrageous. https://www.spacex.com/spacexai/starmind

Thanks!

> SUPERIOR COOLING

> Heat radiates freely into the vacuum of space. Without the need for energy-intensive chillers, cooling towers, fans, or dry coolers necessary in terrestrial data centers, SpaceX’s AI satellites reduce cooling power overhead by an order of magnitude.

Very skeptical, to say the least
