Sundar Pichai, CEO of Google, announced Project Suncatcher to deploy Tensor Processing Units on two satellites by 2027.
Google uses sun-synchronous LEO for solar arrays to harness sunlight, 8x more productive than Earth panels.
81 satellites at 650 km will link via free-space optical links to deliver 10 terabits/sec.
Trillium TPUs show memory irregularities after 2 kilorad.
