Google Launches Project Suncatcher: AI Data Centers in Space

  • On Tuesday, Sundar Pichai, CEO of Google, announced Project Suncatcher to deploy Tensor Processing Units on two prototype satellites by early 2027.
  • With energy demand outstripping supply, Google plans a dawn-dusk sun-synchronous low-earth orbit using solar arrays to harness near-constant sunlight, which could be eight times more productive than Earth panels.
  • To match terrestrial centers, Google’s Tensor Processing Units will link via free-space optical links to deliver tens of terabits per second in a cluster of 81 satellites at 650 kilometers.
  • Radiation tests show Trillium-generation TPUs begin memory irregularities after 2 krad, while Google says launch costs must fall to $200/kg by the mid-2030s for space datacenters to match terrestrial energy costs.
  • Partnering with Planet Labs, satellite imaging provider, Google will test hardware while SpaceX, Starcloud, Jeff Bezos and other startups pursue similar orbiting datacenter plans.
