Google launches four AI chips into orbit for Project Suncatcher

Google says a prototype satellite built with Planet carried four of its TPUs into orbit on SpaceX’s Transporter-18 mission on October 1. Over the coming weeks, it plans to study how the chips handle physical stress, radiation and temperature extremes. Project Suncatcher explores whether machine-learning infrastructure could someday operate at scale in space; Google AI says orbit could offer near-constant sunlight for solar power.
