Google will launch its first space-based AI computing experimental satellite on October 1, equipped with four TPUs running Gemini.
According to TechFlow on Sept. 25, citing TechStartups, Google plans to launch the first experimental satellite for Project Suncatcher on Oct. 1 to test the feasibility of operating AI computing infrastructure in space.
Approximately refrigerator-sized, the satellite will carry four Google TPUs to run Gemini workloads in low Earth orbit hundreds of miles above the surface.
The satellite will launch aboard a SpaceX Falcon 9 rocket on the Transporter-18 mission. Through a partnership with satellite company Planet to deploy AI hardware on an existing platform, Google is advancing its first planned on-orbit hardware test—originally scheduled for 2027—by several months.
The satellite's solar array is expected to generate around 1 kilowatt of power. Due to thermal constraints in space, the TPUs can currently operate continuously on Gemini workloads for only about 15 minutes before needing to pause to allow the thermal management system to recover. Google has also previously conducted vibration and radiation testing on the Trillium TPU, with future plans to explore building large-scale space-based AI computing clusters utilizing solar-powered satellites, TPUs, and high-speed optical communications.
