About
Galactic Brain is Aetherflux’s flagship orbital data center program, announced in December 2025. It represents the company’s expansion beyond pure power beaming into in-orbit compute — leveraging continuous solar energy harvesting to power GPU-class workloads directly in space, putting the sunlight next to the silicon and skipping the power grid entirely.
Each Galactic Brain node is a solar-powered compute satellite operating in low Earth orbit. The initial deployment targets teraflop-class compute capability, scaling to petaflop-class constellations as node count grows. The first commercial node is targeted for Q1 2027, with approximately 30 satellites per Falcon 9 launch and 100+ per future Starship launch. Satellites use optical inter-satellite links to deliver multi-gigabit bandwidth with near-constant uptime, while ~500 ms latency makes the system best-suited for AI inference and batch workloads.
The architecture addresses terrestrial data center bottlenecks — land acquisition, utility connections, and grid-dependent power — that typically require 5–8 years to resolve. By contrast, Galactic Brain nodes can be deployed and operational within months. Radiative cooling in the space environment replaces energy-intensive liquid cooling systems used in ground-based data centers.
