Google confirmed its first Suncatcher prototype satellite, which carries a single Tensor Processing Unit and generates up to 1 kW of power, is online and communicating with ground engineers after launching this month on a SpaceX Falcon 9. Following roughly three weeks of subsystem checks, engineers sent the satellite its first prompt, having it run Google DeepMind's Gemma model to generate a haiku and report on orbital conditions; a Google spokesperson said the satellite is operating nominally.

Google sent a prototype orbital compute satellite, built by Planet Labs, aboard a SpaceX rocket from California, marking the first time one of its Tensor Processing Units has flown in space. The test will check whether the chip can sustain a kilowatt of continuous power, manage heat, and run AI models in short bursts without failure. Google's Travis Beals, who leads the effort called Project Suncatcher, said a more advanced two-satellite demo with laser communication links is planned for next year.

The piece explains how Google's Tensor Processing Units (TPUs), built for AI workloads in data centers, differ from GPUs and NPUs. TPUs are now replacing NPUs in Google's upcoming Pixel 11 phones, with Google claiming up to 3.5 times faster AI processing at up to 3.5 times less energy use. GPUs, meanwhile, remain versatile chips handling gaming, 3D rendering, AI training and crypto mining.
