An AI chip on a Google test satellite has answered its first request from the ground. Google says the prototype satellite for Project Suncatcher, which launched on Oct. 1, received a prompt this week asking the Google AI model it carries, Gemma 4, to write a haiku about being in space. As the satellite passed by Svalbard, Norway, the answer came back: "Blue marble below / Data streams in silent grace / Starlight feeds my core."
The satellite carries Google's own AI chips, called Tensor Processing Units, or TPUs, the same kind the company uses in its data centers. According to a news report, it has four of them but can run only one at a time. Google calls this the first AI response from a data center class TPU in orbit. Since the launch, it says, the team has worked through a checklist of start-up tests, switching on the trays that hold the AI chips and the computer that runs them, and running its first AI test jobs. After the haiku, the team tried space-themed limericks and prompts that asked for reports on the technical status of the satellite's equipment.
Suncatcher is Google's long-term research into whether AI computing could one day run on satellites. Google says satellites in low Earth orbit get near-constant sunlight and can generate up to eight times more solar power than they could on Earth. The catch is that space is hard on electronics. Radiation from the sun and cosmic rays can disrupt them, and with no air to carry heat away, chips are at risk of overheating. Google says its chips held up well when it tested them in a particle beam on the ground, surviving more radiation than a five-year mission in space would bring, but some things can only be tested in space.
That is what the next tests are for. Google says it will now check how the chips perform under heat stress and radiation in orbit, and that proving they can reliably run work in space clears the way for its next step, two linked satellites in 2027.
Answering a short prompt is a first step, not proof that AI computing in space can work at scale or compete on cost with data centers on the ground. Google has not said how long the radiation and heat tests will run or when it will publish what it finds.
