Google's Project Suncatcher satellite runs Gemma 4 in orbit
Google says its Project Suncatcher prototype satellite returned the first AI response generated by a data-center-class TPU in orbit. During a ground-station pass, the team uplinked a prompt to an onboard Gemma 4 open model, which produced a haiku about being in space. Google plans further tests of TPU performance under thermal stress and radiation, ahead of twin interconnected satellites targeted for 2027.
