Google launches AI chips into orbit to test space data centers
Google launched four Tensor Processing Units (TPUs) into low Earth orbit on Oct. 1 aboard a SpaceX Falcon 9 as part of Project Suncatcher, placing them inside a refrigerator-sized satellite called MVP built with Planet. The immediate aim is to measure TPU performance under orbital radiation and thermal conditions after prior radiation tests at UC Davis; Google says the current design lets chips operate roughly 15 minutes before cooling is required. Two more satellites are planned in 2027 to test laser communications, while broader questions remain about cooling, radiation protection, networking, launch costs, debris and emissions.
