There is a growing narrative in the technology sector, fueled by the anticipated launch cadence of heavy-lift vehicles like SpaceX’s Starship, that the future of large-scale AI training lies in orbit. The argument is straightforward: Earth’s power grids are tapped out, water for cooling is scarce, and “NIMBY” (Not In My Backyard) politics make building new data centers difficult. Space, by contrast, offers infinite solar power, a distinct lack of neighbors, and a background temperature of 2.7 Kelvin.
