Google says a data-center-class TPU aboard its Project Suncatcher prototype satellite generated a Gemma 4 response that was received on Earth. After the October 1 launch, the team powered up the systems and ran initial machine-learning tests. A short poem about space was downlinked during a pass over Svalbard, Norway, followed by other poetry and payload-status prompts. The next work tests reliability under thermal stress and radiation, with two interconnected satellites targeted for 2027. This is an early operational milestone rather than proof of commercial scale or a cost advantage.
