Google has identified a new location for its next generation of datacenters, and it’s not in Texas or Brazil. It’s in a precise orbit, “about 400 miles above the Earth’s surface.” This altitude is the new “sweet spot” at the heart of “Project Suncatcher.”
This 400-mile (approx. 640 km) low-Earth orbit (LEO) is a strategic choice. It’s high enough to be above the bulk of the atmosphere, allowing solar panels to be 8-times more productive and avoiding atmospheric drag. It’s also low enough for relatively low-latency data transmission via the planned optical links.
This orbit would be home to Google’s proposed “compact constellations of about 80” satellites. These satellites, packed with AI-powering TPUs, would circle the globe, forming a distributed “datacenter in the sky” that is independent of terrestrial energy grids and water supplies.
This 400-mile-high infrastructure is Google’s proposed solution to the $3 trillion, resource-intensive datacentre boom on the ground. By moving “up,” Google hopes to “minimize impact on terrestrial resources” and find a scalable, sustainable path for AI.
However, this “sweet spot” is also a “sore spot.” It’s the same region that astronomers are trying to protect from “bugs on the windshield” light pollution, and it’s a zone that requires high-CO2 rocket launches to reach. Google’s 2027 prototypes will be the first to test this new 400-mile-high real estate.
