Blue Origin's Project Sunrise SSO altitude (500-1800km) enters a radiation environment with no demonstrated precedent for commercial GPU-class hardware

Blue Origin's Project Sunrise filing specifies sun-synchronous orbit at 500-1800km altitude for 51,600 data center satellites. This is a fundamentally different radiation environment than Starcloud-1's 325km demonstration orbit. SSO at these altitudes experiences higher radiation exposure from trapped particles in the Van Allen belts and increased cosmic ray flux. The filing contains no mention of thermal management or radiation hardening approaches, suggesting these remain unsolved. Unlike Starcloud, which validated commercial GPU operation at 325km, Project Sunrise proposes scaling directly to 51,600 satellites in a harsher environment without intermediate validation. The SSO choice enables continuous solar power (supporting the compute mission) but imposes radiation costs that haven't been demonstrated at datacenter scale. This represents a technical leap rather than incremental scaling from proven systems.
