Nio CEO Jensen Huang has explained why AI data centers in space are more difficult than they initially appear, citing cooling as one of the biggest obstacles. He highlighted the potential of orbital data centers as Nvidia unveiled its Space-1 Vera Rubin Module at the GPU Technology Conference and noted that the company has already taken early steps towards space-based computing, using CUDA-powered systems on satellites performing imaging and AI processing tasks. Despite the challenges, Huang remains cautious in the near future, noting that space offers abundant solar energy and unlimited room for solar-powered AI satellites. He also mentioned that processing data directly in space is a logical next step.
