Google Suncatcher Space Data Center Prototype Satellite Validates TPU in Orbit

Google is advancing its space data center project called Project Suncatcher, whose first prototype satellite was launched into orbit aboard SpaceX's Falcon 9 rocket in early October 2026. On October 31, multiple media outlets reported that the satellite has successfully come online and established communication with the ground. The satellite carries four Google TPU chips as its compute core and can generate up to 1 kilowatt of power. After coming online, the onboard Gemma 4 model completed an inference demo, generating a haiku about being in space; Google also tested other space-themed prompts and telemetry tasks, validating the TPUs' ability to operate in the space environment. The satellite is currently running stably in orbit and maintaining contact with the ground. According to The Verge, Google will next test the TPUs' ability to withstand thermal stress and radiation in orbit, and plans to reach the next milestone of two-satellite interconnection in 2027, with the long-term goal of putting AI data centers into space. The project has now entered its in-orbit validation phase.
