Google Says Project Suncatcher TPUs Go To Orbit Next Week
Google published a look behind Project Suncatcher, its research moonshot to test whether AI compute can run in space. Everything below is Google describing its own project and its own pre flight testing. The launch has not happened yet.
Transcript
Google wants AI chips in orbit. Nothing has launched yet.
Project Suncatcher is Google's research plan for AI compute in orbit. A prototype satellite is scheduled to ride a SpaceX mission next week.
In low Earth orbit, sunlight is near constant. Google says that means up to eight times more solar power than on Earth.
Engineers shook the satellite to mimic a rocket launch. Google says a proton beam test showed the chips survive a five year radiation dose.
All of this testing is Google's own, with no independent verification. Google will test laser links between satellites in twenty twenty seven.
