Google's first space data centre satellite is now online
Google's Suncatcher prototype, carrying one TPU chip, is working in orbit and talking to the ground after launching alongside more than 100 other spacecraft.
The facts
- According to TechCrunch, Google's Suncatcher prototype launched earlier this month on a SpaceX Falcon 9 and is now online and communicating with the ground.
- The satellite carries a single Google TPU and generates up to 1 kW of electricity, so the chip can only run for about twenty minutes at a time.
- Engineers asked the onboard Gemma 4 model to write a haiku as a first prompt. A Google spokesperson said the satellite is operating nominally.
- If the test goes well, two more satellites with advanced chips are planned for 2027, with inter-satellite optical links.
Case notes · Danny's take
Why it matters
Everyone is asking where the power for AI will come from. Google's answer is to look up. This is a tiny test, one chip and twenty minutes at a time, but it checks the weak points: heat, radiation and slow links to the ground. The poem is a gimmick. The real question is whether the hardware survives, and the cost still depends on Starship flying very often.
For traders
Don't trade the haiku. Watch the radiation and thermal results, and whether the 2027 launch stays on schedule. Alphabet's stock also fell this week on ad revenue worries, so don't treat a space test as a market signal.
For builders
The source says ground tests suggest radiation matters less for inference than for training. If that holds in orbit, that is where early space compute will be aimed. Watch how the rival designs handle links between satellites.
