Google plans to launch AI chips into space with Project Suncatcher

Technical challenges include keeping the TPUs cool in vacuum, which Google addresses with radiators and heat pipes, and ensuring data transfer between chips using laser beams. A joint test machine with Planet will be carried by a SpaceX rocket in September 2026 to evaluate vibration, radiation, and cooling in space. Google aims to launch two prototype satellites by early 2027 and test connectivity between them that year.

The project explores whether space‑based AI compute can reduce reliance on terrestrial power and cooling, potentially lowering costs if launch prices fall. It remains a research effort, with viability still uncertain as Google weighs transport, cooling, and communication expenses.
