Google's Project Suncatcher satellite runs TPUs in orbit
Google said the satellite booted its Tensor Processing Units in space and the on-board Gemma 4 model replied to a prompt with a haiku.
Google said its Project Suncatcher satellite successfully booted up its Tensor Processing Units (TPUs) while in orbit, and that the on-board Gemma 4 model generated an AI response from space in reply to a prompt. The announcement was reported by theverge.com.
The response was a haiku about being in space, according to Google. The company said it also tested other space-themed limericks and telemetry prompts on the orbiting hardware.
The test is part of Project Suncatcher, an initiative aimed at eventually placing AI data centers in space. Google launched the satellite earlier in October 2026.
What comes next
Google said its next milestone is a pair of twin interconnected satellites in 2027. Upcoming tests will evaluate how the TPUs perform under thermal stress and radiation exposure in orbit.
