Google's Project Suncatcher has reached an important milestone: its prototype satellite ran the Gemma 4 model on a data-center-class TPU (Tensor Processing Unit) in orbit and sent the response back to Earth.
What happened?
Launched on October 1, 2026 aboard a SpaceX Falcon 9 (Transporter-18 mission) in partnership with Planet, the satellite underwent roughly three weeks of commissioning. This week, during a ground-station pass over Svalbard, Norway, the team sent the first prompt to the onboard Gemma 4 model, asking for a haiku about being in space.
The received response was:
Blue marble below
Data streams in silent grace
Starlight feeds my core. ✨
They then tested thematic limericks and telemetry prompts about system status.
Why it matters
According to Google (official post by Travis Beals, Senior Director of Paradigms of Intelligence), this is the first AI response from a data-center-class TPU in orbit. The satellite carries four TPUs and generates up to about 1 kW, limiting operation to one TPU at a time for roughly 20 minutes. Upcoming tests will evaluate performance under thermal stress and radiation. Plans include two interconnected satellites in 2027 to demonstrate optical links.
