Google Suncatcher's prototype space data center is online and communicating with the ground after launching earlier this month alongside more than 100 other spacecraft on a SpaceX Falcon 9 rocket. The satellite, which carries a single Google Tensor Processing Unit (TPU) 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 on for about twenty 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. ✨ Google said it tested the model with these space-themed limericks (they should have sent a poet?) and, perhaps more importantly, the company asked the spacecraft to report on the orbital conditions around the satellite. A spokesperson told TechCrunch that the satellite was operating nominally. The ongoing test campaign will examine how the chips perform under thermal stress and in the...
