# Radiation hardening imposes 30-50 percent cost premium and 20-30 percent performance penalty on orbital compute hardware

Space radiation creates two distinct failure modes for semiconductor hardware: transient bit flips (zeros turning to ones) requiring error-correcting code memory and continuous checking, and permanent physical degradation where radiation exposure gradually disfigures semiconductor structure until chips no longer function. Protection against these failure modes through radiation hardening adds 30-50% to hardware costs while reducing performance by 20-30%. This creates a fundamental cost-performance trade-off for orbital data centers: either accept higher failure rates with commercial hardware, or pay significantly more for hardened components that perform worse. The Breakthrough Institute presents this as a 'terminal constraint' on near-term ODC viability, though the analysis does not quantify lifetime differences at various orbital altitudes or compare hardening costs to replacement strategies enabled by falling launch costs.
