Orbital Data Centers Prove Harder to Build Than Silicon Valley Expects

IEEE Spectrum reports that space-based data center concepts face fundamental thermal and structural challenges, with leading designs struggling against heat dissipation physics and launch payload limits. Orbital computing remains speculative despite venture interest, as no commercially viable prototype has reached deployment.

For infrastructure planners, terrestrial data-center scaling with fiber-to-edge models remains the realistic path forward; orbital compute is decades away from commercial viability and should not factor into near-term AI workload distribution strategy.
