Google's AI chips reach orbit as Falcon 9 launches the first Project Suncatcher test satellite
Before anyone builds a data center in space, the chips have to survive the trip, and Google has started finding out.
A SpaceX Falcon 9 carried Google's first Project Suncatcher prototype into orbit on October 1, lifting off at roughly 2:32 p.m. Eastern with Tensor Processing Units aboard, the same class of chip Google uses to train and run its AI models. The flight is a test rather than a service: engineers want to see how the processors handle launch and the space environment, and to trial a novel cooling system for the heat the chips throw off. Google said the hardware held up remarkably well under simulated radiation at UC Davis, enough to take more ionizing radiation than five years in orbit would be expected to deliver. Two more experimental satellites are planned for 2027 to test laser links between potential orbital data centers.
Scripture for Reflection
“Lift up your eyes on high: Who created all these? He leads forth the starry host by number; He calls each one by name. Because of His great power and mighty strength, not one of them is missing.”
As our instruments climb higher, we can let the night sky turn our attention back to the One who made it.
