SpaceX and Google race to build AI data centers in space as scientists question the physics
SpaceX filed to launch up to 1 million satellites for orbital computing, while Google plans its Project Suncatcher test in 2027. The companies promise to solve AI's escalating electricity demands with solar-powered space data centers, but scientists warn of unresolved challenges in thermal management, radiation shielding, and economics that could make the vision unviable for years.
