Google Runs Gemma on TPU in Orbit, First Step Toward Sun-Powered Space Data Centers
shashib · x · 2026-11-02
Google's Project Suncatcher satellite hit a milestone within 30 days of launch: a Gemma model ran on a data-center-class TPU in orbit, with the first AI response (a haiku about orbit) beamed back to a ground station over Svalbard, Norway — what Google calls the "Hello World" for orbital AI compute.
Key facts:
- The satellite, built with Planet, launched Oct 1 on a SpaceX Falcon 9; Google announced the response on Oct 30; 4 TPUs on board
- Google's cost case requires launch prices below $200/kg by the mid-2030s; solar energy per panel in orbit is 8x that on the ground
- Over the next year Google will measure how much AI work each satellite can deliver within its heat and power budget — heat is the main constraint, forcing pauses when exceeded
This is effectively a hyperscaler's answer to where the power for the next wave of AI capacity will come from: putting compute where solar power is abundant.
