Google's first experimental space-based data center is operational after launching earlier this month, successfully running its Gemma 4 AI model aboard a satellite and generating a haiku about being in orbit. TechCrunch reports: The satellite, which carries four Google Tensor Processing Units (TPUs) and generates up to 1 kW of electricity, is intended to pave the way for future networks of close-flying satellites performing large inference workloads in orbit. However, the power demands of the TPU mean it can only turn one on for about 20 minutes at a time, complicating the already tricky business of space-to-ground communications. After a commissioning process that tested out the satellite's subsystems over about three weeks, the spacecraft was ready to work. When engineers on the ground sent their first prompt this week, they asked the model pre-loaded onto the satellite, Google DeepMind's Gemma 4, to write a haiku about being in space. And thus: Blue marble below Data streams in silent grace Starlight feeds my core. The ongoing test campaign will examine how the chips perform under thermal stress and in the space radiation environment. [...] If the TPUs onboard this spacecraft prove capable, the next step will be launching two more satellites equipped with the advanced chips in 2027. Those spacecraft will support higher power generation and demonstrate inter-satellite optical links.
