Google's Suncatcher space data center prototype is online and communicating

Key points

• Prototype launched earlier this month on a SpaceX Falcon 9 with more than 100 other spacecraft.
• Satellite carries one Google TPU, generates up to 1 kW, and can run only about twenty minutes at a time.
• Google DeepMind's Gemma 4 model, preloaded on board, answered a first prompt to write a haiku about space.
• Next: two more TPU-equipped satellites planned for 2027 to test higher power and inter-satellite optical links.

Why it matters for marketers: Marketers should note the on-orbit test results will be the first real-world check of radiation effects on AI chips, a claim that remains unproven until those results are published.
