Space Companies Propose Orbital Data Center Constellations
SpaceX filed with the FCC on January 30 for up to one million compute satellites, and Blue Origin followed with Project Sunrise proposing 51,600 satellites plus a 5,408-satellite TeraWave backhaul. Startups such as Starcloud raised $170 million and launched an Nvidia H100 on orbit. Scientists warn heat (≈1,200 m² radiator per MW), radiation, latency, and cost (~$50 billion per GW) make large-scale orbital data centres currently impractical.
Scoring Rationale
High-impact industry reporting: authoritative FCC filings and funding signals raise relevance and scope, while detailed physics and cost constraints (radiators, radiation hardening, latency, ~$50B/GW) limit near-term feasibility. Scored up for scope, credibility, and relevance; slightly moderated because it is largely an analytical synthesis rather than a technological breakthrough.
