Google's first data center satellite, equipped with four Tensor Processing Units generating up to 1 kW, is now online in orbit to test large inference workloads in space, though TPU power limits restrict it to running a single chip for about 20 minutes at a time.
Google's Project Suncatcher space AI data center moonshot completes its first "hello world" test: successfully running the Gemma model on a custom-built TPU system at an altitude of about 500 miles and receiving a haiku about space in response, validating the feasibility of on-orbit AI computing.
