Google receives an AI response from orbit

Google’s October 30 update says its onboard Gemma 4 model returned a space-themed haiku after receiving a prompt from a ground station. The response came down near Svalbard, Norway. The October 1 launch had been followed by commissioning, including powering equipment and early machine-learning tests. Further prompts requested poems and reports on payload systems. The team will continue testing thermal stress and radiation exposure before its planned milestone of two connected satellites in 2027.

TechCrunch reports a practical constraint behind the demonstration: the satellite carries four Tensor Processing Units, Google’s AI processors, but power demands allow only one to operate for about twenty minutes at a time. Its correction explicitly distinguishes the installed chips from those operating simultaneously. A Google spokesperson told the publication that the satellite was operating normally. The report describes the prototype as preparation for possible networks handling larger workloads in orbit, rather than an already operating network.

Google’s September engineering explanation clarifies the work still needed. Without airflow in space, cooling uses radiators; the team tested heat pipes and radiators in a chamber simulating temperature and vacuum conditions. Orbital observations will inform design revisions. Future clusters would also need precise knowledge of neighboring satellites’ positions to maintain high-bandwidth laser connections over short distances. Those connections are another planned test, so producing an answer and demonstrating a connected computing system remain separate milestones.
