Google Puts AI Chips to the Test with Space-Bound Prototype Satellite

Google has announced that it will launch a prototype satellite as part of its Project Suncatcher initiative, aimed at determining whether space is an ideal environment for machine learning. The satellite will be launched on October 1 via a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

The company's goal with this project is to test the functionality of its AI chips, known as Google Tensor Processing Units (TPUs), in space. According to Google, satellites in low Earth orbit can access near-constant sunlight, generating up to eight times more solar power than on Earth.

Google first unveiled Project Suncatcher last November, with a plan to launch two prototype satellites by early 2027. However, the company is not sending a full data center but rather an experimental version of one.

In its blog post ahead of the scheduled launch, Google detailed the behind-the-scenes work for Project Suncatcher, including testing whether its AI hardware can survive in space. Initial results have shown that the Trillium TPUs hold up remarkably well and can survive a radiation total ionizing dose greater than what they would receive during a five-year space mission.
