Google launched its first orbital compute satellite into space today on a SpaceX rocket from California, marking the tech giant's debut of an advanced chip in orbit. Built by Planet Labs, the satellite will test whether Google's Tensor Processing Unit can function in space by providing continuous power, managing cooling, and running model tests. Travis Beals, the Google executive managing Project Suncatcher, noted that ground testing cannot fully replicate the real-world environment needed to develop large-scale compute clusters in orbit.
The current mission uses a standard Planet Labs platform, with future purpose-built demo satellites expected to launch next year to test laser communication links. Google envisions a long-term network of 81 satellites flying in formation to process parallel AI workloads. However, scaling up orbital data centers cost-effectively requires future rockets, and Google's newly published white paper in Joule estimates that SpaceX's Starship will need to achieve 1,800 launches over the next decade to reach projected cost reductions.
This initiative highlights the growing intersection of artificial intelligence and space infrastructure development as tech companies look toward future orbital workloads. While SpaceX faces significant hurdles to reach the required launch frequency, Google's ongoing tests confirm that its chips can survive space radiation.
