Google said Friday that a satellite in its Project Suncatcher experiment ran an on-board language model and sent a generated reply back to Earth¹. The Verge, citing the same company blog, reported the same claim.

Google said it booted Tensor Processing Units on the spacecraft and that Gemma 4 completed a prompt to write a haiku about being in space¹. The company said it then tried other space-themed limericks and telemetry prompts reporting payload status¹.

The Verge described Suncatcher as an experimental effort that could eventually put AI data centers in space, and said Google launched the satellite earlier this month. Google’s blog said the prototype launched on Oct. 1 as a first step in research on powering AI compute in space¹.

Google said it will next test how the chips perform under thermal stress and radiation in orbit, and that confirming they can run workloads in space is meant to support a later milestone of twin interconnected satellites in 2027¹. Neither account included independent confirmation of the satellite’s output¹.
