Google is preparing to send its artificial intelligence chips into orbit for the first time as part of Project Suncatcher, a research initiative exploring whether large-scale AI computing infrastructure could eventually operate in space. The company plans to launch a prototype satellite next week aboard SpaceX’s Transporter-18 rideshare mission in partnership with Planet Labs.
The satellite will carry Google’s Tensor Processing Units (TPUs) into low Earth orbit, where engineers will study how the hardware performs under launch forces, radiation and extreme temperatures. Google will also test a cooling system based on heat pipes and radiators because conventional air cooling does not work in the vacuum of space.
Project Suncatcher is aimed at a longer-term vision of using solar-powered satellites as distributed AI computing infrastructure. Google says the initial mission is primarily a learning exercise designed to collect orbital data and identify potential failure points, rather than demonstrate a functioning space-based data center.
Google plans another milestone in 2027, when two satellites are expected to test high-bandwidth laser links needed to connect future clusters of AI processors in orbit. However, high launch costs, thermal management, radiation protection and satellite manufacturing remain significant challenges before space-based AI data centers could become commercially viable.
