❯ Google’s first AI-chip satellite reaches orbit, starting a test of whether data centers can work in space

Four TPUs in orbitOn October 1, Google launched the first prototype satellite of Project Suncatcher on a SpaceX Falcon 9 rideshare mission. According to the Wall Street Journal, the satellite has made contact with the ground and is operating normally. Built with Planet, it carries four Google TPUs.

First, can it survive?This is a learning mission that runs no real workloads; it mainly measures how the chips handle launch vibration, cosmic radiation and extreme temperature swings. With no air in space, fans cannot cool the chips, so the satellite must shut down to cool after about 15 minutes at full power. Google plans to test laser links between two satellites in 2027.

Chasing more powerData centers on the ground face shortages of power and land, and residents in many places oppose new projects. Space offers more abundant solar power and takes no land, which is why Google, SpaceX and others are betting on orbital compute. But cooling, maintenance and data transmission costs are far from solved, and real AI workloads in orbit are still a long way off.

▪ SIGNALSending data centers into space reveals less about tech ambition than about how tight power and community resistance on the ground have become.
