Google has successfully tested its AI hardware in orbit as part of the Project Suncatcher initiative. The MVP satellite, which is roughly the size of a refrigerator, was launched on October 1, 2026, aboard a SpaceX Falcon 9 rocket during the Transporter-18 mission.
The spacecraft is equipped with four Trillium-generation Tensor Processing Units. These chips provide computing capacity comparable to a single data center server, supported by solar panels that generate approximately 1 kW of power.
Due to thermal management challenges in the vacuum of space, the system operates in 15-minute intervals before requiring a shutdown for cooling. Prior to the flight, the hardware underwent radiation testing at UC Davis to simulate five years of orbital exposure.
Project Suncatcher, announced in late 2025, investigates the potential of using solar energy in low Earth orbit to power AI workloads. Google stated that orbital solar panels could theoretically produce eight times more power than those on the ground.
While the current test confirms the functionality of the hardware, Google has no immediate plans to deploy operational orbital data centers due to unresolved technical hurdles. Further testing, including laser communication links, is scheduled for 2027.
