Google’s Suncatcher satellite runs Gemma 4 in orbit
First merged summary.
Google’s Project Suncatcher prototype is online after an October launch and has run an onboard Gemma 4 model from space.
Google said its Project Suncatcher prototype space data center is communicating with Earth after launching this month on a SpaceX Falcon 9 with more than 100 other spacecraft. After about three weeks of commissioning, engineers prompted a preloaded Gemma 4 model; it wrote a haiku and reported orbital conditions. TechCrunch reports the craft carries one TPU, generates up to 1 kW, and can power the chip for about twenty minutes; The Verge refers to onboard TPUs. A spokesperson said the satellite was operating nominally. Google plans heat and radiation tests, including bit flips, and twin higher-power satellites with optical links in 2027.
- Launched this month on a Falcon 9 with more than 100 other spacecraft.
- About three weeks of commissioning preceded the first model prompts.
- TechCrunch: one TPU, up to 1 kW, about twenty minutes of chip power.
- The Verge: Google also tried limericks and telemetry prompts in orbit.
- Ground tests found radiation a larger problem for training than inference.
- Two higher-power satellites with optical links are planned for 2027.
