Project Suncatcher, Google's test for putting AI accelerators in orbit, launched on Thursday, October 1, 2026. An experimental satellite carrying Tensor Processing Units (TPUs) rode a SpaceX Falcon 9 on the Transporter-18 rideshare from Vandenberg Space Force Base in California.
What happened?
Scientific American recorded the launch at about 2:32 p.m. Eastern Time. CNN describes the flight as the first satellite test of Google's orbital data-center project. Travis Beals, Google's senior director of paradigms of intelligence, said this first Project Suncatcher flight is about seeing what works and finding failure points. Google plans two more satellites in 2027.
What is on the satellite?
According to Ars Technica, the prototype, nicknamed MVP, is about the size of a refrigerator and carries four TPUs. Solar panels supply about 1 kilowatt. Google is expected to run Gemini models on the chips, but cooling only supports bursts of about 15 minutes. After that the TPUs must shut down. There is no air in vacuum to carry heat away.
On the ground, some chips already went through a proton beam at the University of California, Davis. Google said the chips held up remarkably well. The test satellite was integrated into a bus already built by Planet Labs.
Why it matters
AI data centers use a lot of power and face local pushback. The orbital bet uses steady sunlight and the cold of space. This is still an experiment, not a product. Caleb Henry of Quilty Space told CNN that 1 kW is modest even for telecom satellites. Cost, inter-satellite lasers, and dedicated launches remain open.
What changes in practice?
Nothing changes for Gemini users today. Google now has its own hardware in orbit and a 2027 plan for two more satellites.
