Google's first orbital data center satellite is online and reporting normal operation
Radiation testing and two follow-on satellites in 2027 will determine whether space-based computing can scale beyond a single prototype.
Google's prototype orbital computing satellite, part of its Project Suncatcher effort, is up and talking to ground stations after launching earlier this month on a SpaceX Falcon 9 alongside more than 100 other spacecraft. Following roughly three weeks of subsystem checks, engineers sent a prompt that had the on-board Gemma 4 model produce a haiku about being in space, and the spacecraft reported that it is operating normally. The satellite carries one Tensor Processing Unit and produces up to 1 kW, but the chip's power draw limits it to about twenty-minute runs, which complicates communication with the ground. Next, Google will test how the chip handles thermal stress and radiation, since radiation-induced bit flips could corrupt data without tripping standard monitoring. If those tests go well, two more satellites with the advanced chips are planned for 2027 to demonstrate higher power generation and inter-satellite optical links.
Why it matters
The prototype shows that a data-center chip can run in orbit and talk to ground stations, but its short twenty-minute runtimes and exposure to radiation-driven data corruption are open problems. The planned radiation and thermal tests, followed by the 2027 satellites that would demonstrate higher power and optical links between spacecraft, are what will show whether orbital computing is a practical idea or remains a demonstration.
