Google runs its Gemma AI model on TPUs aboard a prototype satellite

Gemma 4 in Space. 🛰️ Google Research's Project Suncatcher just booted up data-center TPUs aboard a prototype satellite and ran Gemma 4 in Low Earth Orbit. For its "Hello World" test, engineers on Earth asked Gemma 4 to write a haiku about being in space. Passing over Svalbard, Norway, the satellite downlinked its response: Blue marble below Data streams in silent grace Starlight feeds my core. ✨ Built with Planet and running on a ~1kW solar budget, the team is now testing how TPUs handle heat and radiation in space.
