Google's Project Suncatcher has achieved a significant milestone by successfully running an AI model on a satellite in orbit and receiving its first response back on Earth. The prototype satellite, launched on October 1, completed its initial tests and sent a command to the onboard Gemma 4 model, which generated a haiku about being in space. Google CEO Sundar Pichai described this as a 'hello world' milestone for the project. The next phase will involve testing the performance of the Tensor Processing Units (TPUs) under thermal stress and radiation exposure in orbit. If successful, Google plans to launch two more satellites in 2027, which will have greater power-generation capabilities and demonstrate inter-satellite optical links. The ultimate goal is to create networks of closely flying, solar-powered satellites that can work together on large AI workloads.
