I data center nello spazio promettono di salvare il pianeta. E anche di rovinare l'orbita terrestre

SpaceX and xAI are collaborating on an ambitious project to launch one million satellites that will function as orbital data centers. This initiative aims to leverage the unique environment of space for AI computations, promising enhanced efficiency and potentially lower costs compared to terrestrial data centers. The concept envisions a network of interconnected satellites capable of processing vast amounts of data. The proposed orbital data centers would be situated in sun-synchronous orbits between 500 and 2,000 kilometers above Earth. These satellites would communicate with each other and with the Starlink network via optical laser links. A significant advantage cited by SpaceX is the optimal performance of solar panels in space, free from atmospheric and climatic interference, making it an attractive alternative for AI data processing. However, the project faces considerable technical hurdles, including the challenge of heat dissipation in the vacuum of space, as satellites act as natural insulators. Additionally, cosmic radiation poses a risk to the advanced chips used in AI processors, which are susceptible to errors from energetic particles. The long-term viability and environmental impact of such a large satellite constellation are subjects of ongoing discussion.
