Google's Project Suncatcher puts four AI chips in orbit

Google's Project Suncatcher dates back to November 2025, when the company said it would explore how an interconnected network of solar-powered satellites equipped with its Tensor Processing Unit (TPU) AI chips could harness the full power of the Sun. The launch with Planet Labs is the first physical test of that idea.

The broader interest in orbital data centers followed SpaceX's filing with the Federal Communications Commission in early 2026 for a network of up to 1 million data-center satellites, and Blue Origin's March proposal for 51,600 satellites under Project Sunrise. Elon Musk said at the World Economic Forum in January that the lowest-cost place to put AI will be space, within two years, maybe three. Google had already been working on the concept before that attention arrived.

Obstacles remain. Jeff Thornburg, CEO of Portal Space Systems, has said the large and heavy solar arrays needed would be expensive to transport, even as SpaceX cut estimated launch costs by 95% since 2008 to about $1,000 per kilogram, according to ARK Invest research. Repairing equipment in space is also harder. James Manyika, Google's senior vice president for research, told the New York Times that Google researched for about 15 years before anything showed up, and he expects this to look similar.
