Google has announced Project Suncatcher, a research initiative that explores the concept of solar-powered AI data centres orbiting in space. The concept proposes compact constellations of satellites equipped with Google’s Tensor Processing Units (TPUs), which would draw continuous energy from the Sun and communicate via high-speed optical links.

In a recent preprint paper titled “Towards a Future Space-Based, Highly Scalable AI Infrastructure System Design,” the company provided an overview of the project. The study claims that launching AI computing infrastructure into orbit could unlock enormous energy potential while reducing reliance on terrestrial resources. Reports state that solar panels in orbit can run almost continuously and gener
