Google has announced that it will launch a prototype satellite equipped with its proprietary AI chip, the "TPU," on October 1, 2026, as an initial experiment for "Project Suncatcher"—a research project aimed at operating AI data centers in Earth's orbit. The launch is scheduled to be conducted using SpaceX's Falcon 9 rocket.

This project aims to explore whether it is possible to operate low-cost, large-scale AI data centers powered by solar energy by coordinating multiple artificial satellites in Low Earth Orbit (LEO).
In this experiment, Google will investigate the effects of the unique space environment on the TPUs. Key verification items include errors such as bit flips caused by radiation, intense vibration and acceleration, and thermal management in a vacuum environment. In preliminary radiation testing conducted on Earth, the "Trillium"—Google's 6 generation TPU—demonstrated high durability.
Additionally, since there is no airflow in space, verification of cooling technologies to efficiently dissipate chip heat will be conducted. Furthermore, regarding laser communication technology for high-speed, high-precision communication between satellites, Google plans to conduct demonstration experiments when it deploys 2 artificial satellites in 2027.
