Google's TPUs Catch a Falcon 9 Ride to Test Solar-Powered AI in Orbit 🛰️

Alphabet's Google is sending its Tensor Processing Units (TPUs) to low Earth orbit aboard a SpaceX Falcon 9 rocket on the Transporter-18 rideshare mission from Vandenberg Space Force Base in California, marking the company's first in-space test of hardware tied to its Project Suncatcher initiative. The Falcon 9 will carry 130 payloads, with Google's prototype satellite among the spacecraft heading to orbit.

Google built the mission with Planet to evaluate how the chips handle launch vibration, radiation exposure and cooling in a vacuum. "This first launch is about seeing what works, identifying points of failure," Google executive Travis Beals said. Data from the flight will inform subsequent Project Suncatcher tests.

Project Suncatcher explores whether solar-powered satellites could eventually host large AI workloads. Google has estimated that satellites in low Earth orbit could receive enough sunlight to generate considerably more solar power than comparable ground-based panels, though the company says it remains in the testing phase.

Engineers still need to address cooling, radiation resistance and inter-satellite communication before any orbital computing network could operate at scale. The Transporter-18 mission is designed to give Google a baseline read on hardware behavior under real space conditions, with the next set of test parameters expected to follow the flight.
