Google has lofted four of its latest Trillium-generation AI chips into orbit aboard a prototype satellite, a first real-world test of whether data-center-class computing can run in space. The satellite lifted off Oct. 1 aboard SpaceX's Transporter-18 rideshare mission as part of Project Suncatcher; Google says it has established contact and the satellite is operating as expected.

The experiment will answer three questions: whether AI processors can survive launch forces and radiation, whether their heat can be dissipated in a vacuum, and whether clusters of satellites can exchange enough data to function as a larger computing system. Google announced Project Suncatcher in 2025 as a way to explore solar-powered computing in orbit as an alternative to power-hungry ground data centers.

The stakes are significant. The International Energy Agency projects global data-center electricity use rising from about 485 terawatt-hours in 2025 to around 950 TWh by 2030, with consumption from AI-focused facilities roughly tripling over the same period.

The project's premise is to process AI workloads where the data is generated in space rather than beaming everything back to Earth — an approach echoed by the same Transporter-18 launch, which also carried the Satlyt startup's orbital-AI software.
