Google puts its first AI chip satellite in orbit
The Project Suncatcher prototype carries four TPUs to see how AI chips cope with space, and Google’s own maths says orbital data centres need about 1,800 Starship flights.
Google’s first Project Suncatcher satellite reached orbit on Thursday 1 October 2026 aboard SpaceX’s Transporter-18 rideshare, and Google says it is in contact and working as expected. Built with Planet, the satellite carries Google’s TPU chips to see how AI hardware handles launch, radiation and swings of heat and cold.
The fridge-sized satellite holds four TPUs and runs Google’s Gemma models in 15-minute bursts to manage heat, NPR reports. Two more satellites follow in 2027 to try laser links between them.
The case for the project is sunlight: Google’s 2025 research paper said a solar panel in the right orbit can produce up to eight times more than on the ground. The obstacle is launch. Google’s own estimate needs about 1,800 Starship flights over a decade, roughly 180 a year, for orbital data centres to make sense, TechCrunch reports. Starship has never flown more than five times in a year.
For buyers of AI services, the energy squeeze behind the project is the point. Labs are looking as far as orbit for power, a measure of how tightly compute costs track electricity.
