Google Operates Artificial Intelligence Model on Prototype Satellite in Orbit

Google successfully ran an artificial intelligence model on an orbiting prototype satellite and received a complete response back on Earth, marking a major milestone for its Project Suncatcher initiative.

The prototype spacecraft launched on October 1 on a SpaceX Falcon 9 rocket alongside more than 100 other payloads, according to TechCrunch and ANI News.

The satellite carries a single Google Tensor Processing Unit and generates up to 1 kW of electricity to power its onboard operations in low Earth orbit.

Engineering teams on the ground sent a prompt to the onboard Gemma 4 model asking for a haiku about being in space.

The satellite transmitted the resulting verse back to Earth, producing lines about starlight and data streams.

Google Chief Executive Officer Sundar Pichai announced the achievement in a social media post, describing the test as a key step forward.

"After launching our prototype satellite a few weeks ago, we've now successfully sent a command up to orbit, booted up the TPU, ran the prompt, and received our first complete response back on earth - a haiku!" said Pichai.

The initiative explores whether space environments can support scalable machine learning infrastructure and large inference workloads in orbit.

Because the satellite generates limited electricity, the processing unit can operate for only about 20 minutes at a time during communication passes.

Following the initial success, engineers tested additional telemetry prompts and space-themed limericks to check system performance.

"Next, we will continue with a series of tests to evaluate how TPUs perform under thermal stress and radiation exposure in orbit," Google said in a blog post.

Radiation in space can trigger bit flips that corrupt stored data without activating standard monitoring tools, making orbital testing crucial for hardware verification.

If the current mission proves successful, the company plans to launch two interconnected satellites equipped with advanced chips in 2027.
