Google to launch prototype satellite to test TPUs in space next week

Google has confirmed that it will launch a prototype satellite next week as part of Project Suncatcher, a research effort to assess whether its tensor processing units (TPUs) can operate in the harsh environment of space.

The satellite will ride on SpaceX’s Transporter‑18 rideshare mission, developed in partnership with Planet. Its purpose is to collect in‑orbit data on how TPU chips cope with the intense vibrations, acceleration forces of up to 50‑100 g, radiation, and extreme temperature swings experienced during launch and while in low‑Earth orbit.

Google’s senior director for Paradigms of Intelligence, Travis Beals, said the project aims to explore the potential for large‑scale AI computing infrastructure in space, noting that satellites in low Earth orbit can receive up to eight times more solar power than on the ground. He added that the ultimate goal is to link multiple satellite constellations to handle larger AI workloads.

Prior ground testing at UC Davis’s Crocker Nuclear Laboratory showed the Trillium TPUs could survive radiation doses exceeding those expected over a five‑year mission. The upcoming launch will provide the first real‑world validation of those results.

Google recently announced its largest single investment in Europe, pledging €13 billion to Finland’s digital infrastructure over the next two years, including data‑centre expansion and clean‑energy projects.
