Google plans satellite launch to test AI data center in space

Google just revealed one of its most audacious infrastructure bets yet: putting AI chips in space and powering them with the sun. The initiative, called Project Suncatcher, envisions constellations of solar-powered satellites running Google’s custom Tensor Processing Units in low-Earth orbit, effectively turning space itself into a data center. The company announced the project on November 4, 2025, framing it as a long-term answer to one of AI’s most stubborn bottlenecks. Training and running large machine learning models requires enormous amounts of energy, and terrestrial data centers are increasingly bumping up against power grid limitations. What Project Suncatcher actually involves The plan starts modestly, at least by space standards. Google has partnered with Planet Labs, the San Francisco-based satellite imaging company, to build and operate two prototype satellites. Each one will carry Google’s TPUs into a dawn-dusk sun-synchronous orbit, a trajectory that keeps the spacecraft in near-constant sunlight. That orbital sweet spot is the whole thesis. Google claims satellites in this configuration could achieve up to eight times the solar panel productivity compared to ground-...
