A haiku from orbit
Google's first space data center test just answered back. Engineers uplinked a prompt to the Project Suncatcher prototype satellite, its onboard Gemma 4 model ran on a Google TPU in orbit, and the reply came down during a pass over Svalbard, Norway. The answer was a haiku about being in space.
The satellite was built with Planet and launched on October 1, 2026 on SpaceX's Transporter-18 rideshare.
What's on board
The prototype carries four TPUs (Google's AI chips) and up to 1 kW of power, enough to run one chip at a time for about 20 minutes. Before launch, Google tested its TPUs under a proton beam: the memory only showed glitches at roughly three times the radiation dose expected over five years in orbit.
Why put AI in space?
Power. Google's research says a solar panel in the right orbit can be up to 8x more productive than on Earth, with near-constant sunlight and less need for batteries. AI data centers need huge amounts of electricity, so that matters.
The money question is launch costs. Google estimates that if launch prices fall below about $200 per kilogram by the mid-2030s, the energy cost of space compute could be roughly comparable to a data center on the ground. That's an estimate, not a guarantee, and reusable rockets like SpaceX's Starship are a big part of that path.
Next steps: thermal and radiation tests in orbit, then two satellites with optical links planned for 2027. For more on the data center boom on the ground, read our brief on AWS and AI data centers.
What it means for your money
- AI is now an energy story. Whoever finds cheaper power for AI chips gains an edge.
- Launch costs are the key number. Cheaper rockets could open new markets beyond satellites.
- It's early. This is a one-satellite prototype; the business case is still years away.
