Project Suncatcher runs a prompt on an orbiting TPU and returns a haiku

What happened

Project Suncatcher has received its first complete response from its prototype satellite, a haiku. Sundar Pichai says the satellite launched a few weeks ago, and the team has now successfully sent a command to orbit, booted up the TPU, run the prompt, and received the response back on Earth.

The story so far

Google’s Project Suncatcher prototype satellite has run an AI prompt in orbit and returned its first complete response to Earth—a haiku—according to Sundar Pichai. He said the team sent a command from Earth, booted the satellite’s TPU and received the result. TechCrunch reported that the satellite was operating normally and running Google DeepMind’s Gemma 4 on a single TPU to write poetry and report orbital conditions. The prototype is a test toward possible AI data centers in space. It generates up to 1 kW of power, but its TPU can operate for only about twenty minutes at a time, according to TechCrunch. Google says it will next evaluate how TPUs perform under thermal stress and radiation exposure in orbit. If the onboard TPU proves capable, TechCrunch reported, the next step would be to launch two more satellites in 2027 to demonstrate higher power generation and optical links between satellites.
