Google launches Project Suncatcher prototype to test AI chips in orbit

Google has launched a refrigerator-sized prototype satellite carrying four of its Tensor Processing Units, beginning an in-orbit test for Project Suncatcher, its effort to develop solar-powered AI data centers in space.
Built with satellite company Planet and carried into orbit by a SpaceX rocket from California, the spacecraft will test whether Google’s machine-learning chips can withstand launch stresses, radiation and extreme temperature changes. The TPUs are expected to operate for 15 minutes at a time because of the prototype’s power and cooling limits. NPR reported that they will run a version of Google’s open-weight Gemma model and answer simple queries.
Planet will commission the satellite before Google begins testing the processors. The companies aim to keep the mission operating for a year. Google plans to launch two more purpose-built satellites next year to test whether they can exchange data through laser links.
Project Suncatcher ultimately envisions groups of closely coordinated satellites performing AI computations using solar power and transmitting results to Earth. TechCrunch reported that one proposed configuration consists of 81 satellites.
Substantial engineering and economic obstacles remain, including launch capacity, radiation exposure, cooling hardware and the large solar arrays needed to supply data-center-scale power. The current mission is a limited demonstration intended to establish whether Google’s TPUs can operate reliably in space.
HOW THIS STORY WAS MADE
Written from 8 articles, 3 with the publisher's own text; 8 independent newsrooms once syndicated copies count as one; this version written 54 h after the record first saw the story; the editor revised it.

WHAT THE EDITOR DID
The second model checked the writer's draft against the same sources and changed it before publication. Struck words were in the draft; underlined words are its corrections.
WHAT IT FLAGGED editor revise: The story needs removal of two unsupported details about dividing computing work and larger future systems. - "Google plans to launch two more purpose-built satellites next year to test whether they can divide computing work and exchange data through laser links.": The sources say next year's two satellites will test their connection/collaboration via laser communications links, but do not say they will test whether they can divide computing work. - "while larger future systems could require far more spacecraft.": No provided source says larger future systems could require far more spacecraft; Scientific American says constellations of thousands, but the story attributes the configuration detail to TechCrunch and this future-systems claim is not sourced as written.
