Google has unveiled Project Suncatcher, an initiative to deploy AI-powered data centers in low-Earth orbit. The project aims to utilize solar-powered satellites equipped with custom Tensor Processing Units to overcome energy limitations faced by terrestrial data centers.
The company partnered with Planet Labs to develop two prototype satellites, which are scheduled for launch by early 2027. These satellites will operate in a dawn-dusk sun-synchronous orbit, where solar panel productivity is projected to be up to eight times higher than on the ground.
The mission will test TPU performance, including thermal management, radiation resilience, and optical inter-satellite communication. Google has already conducted radiation testing on its Trillium TPUs, confirming they can withstand doses equivalent to a five-year mission.
Alphabet, the parent company of Google, holds an equity stake in Planet Labs, which will handle the satellite design and construction. The project is currently viewed as a foundational step rather than a commercial product.
Google anticipates that orbital compute infrastructure could reach economic parity with terrestrial energy costs by the mid-2030s. This projection relies on launch prices falling below $200 per kilogram.
