Google launches prototype satellite to test TPUs in orbit
Google is preparing to launch a prototype satellite under Project Suncatcher to test whether its Tensor Processing Units can operate in low Earth orbit, with an initial launch scheduled on SpaceX's Transporter-18 rideshare. The company reported vibration tests that simulated rocket launch forces and proton-beam radiation trials at UC Davis that exceeded expected five-year radiation doses, and it has tested heat-pipe and radiator cooling concepts in a thermal vacuum chamber. The orbital mission will collect real-world data on hardware reliability, thermal management and communications needs, and will inform future satellite designs and a planned 2027 laser link experiment.
