Google Project Suncatcher TPU sends first orbital AI response

Google announced that its Project Suncatcher prototype satellite has produced the first AI response from a data center-class TPU in orbit.

• The team said it completed the commissioning checklist, powered up the host and TPU trays, and achieved a “Hello World” milestone by sending a prompt to the onboard Gemma 4 model and receiving a haiku back from orbit.
• Google said it will continue testing the TPUs under thermal stress and radiation exposure in orbit, with the next milestone set for twin interconnected satellites in 2027.
