Aetherflux unveils 'Galactic Brain' — orbiting AI data centres powered by space-based solar

Aetherflux's plan joins a wave of proposals to host large AI compute in orbit as a way to access near-constant solar power and sidestep terrestrial grid constraints, aligning with moves by tech leaders to explore lunar and orbital data centres (see Musk, Bezos and Pichai weighing lunar and orbital AI data centers).

The concept relies on recent technical progress in space power and on-orbit fabrication — including record beamed-power ground tests and demonstrations of in-orbit solar-array manufacturing — which are clearing key technical hurdles for sustained orbital power infrastructure (see Star Catcher beams record test and Dcubed to demonstrate in-orbit manufacturing).

Framing the effort as an "American power grid in space" elevates policy, industrial and investment questions already flagged by analysts urging national strategies for space-based data centres, making this development relevant to national strategy and commercial planning (see think tank urging Europe to rapidly build a large-scale strategy for space-based data centres).
