According to Lex Fridman on X, Jensen Huang said Nvidia has engineers actively researching orbital data centers to leverage continuous solar power and dissipate heat via giant radiators in vacuum, addressing challenges like radiation, performance degradation, redundancy, and continuous testing, as reported in Fridman’s interview timestamps covering AI data centers in space. According to Sawyer Merritt’s post referencing the same interview, Huang emphasized there is no conduction or convection in space and heat must be evacuated by radiation, framing thermal management and radiation-hardening as primary engineering blockers for AI scale-out in orbit.
