Google Sends AI Chips to Space for Harsh Environment Test

Google's ambitious Project Suncatcher has launched into space aboard a SpaceX rocket. The mission, which took place on October 1, aims to test the company's Tensor Processing Units (TPUs) in the harsh environment of low-Earth orbit.

The TPUs have already been put through their paces on land, with some subjected to simulated solar radiation and cosmic rays at a proton beam facility at the University of California, Davis. According to Google, the chips 'held up remarkably well' and could handle more ionizing radiation than expected over five years in space.

Project Suncatcher will also test a new cooling system designed by Google's engineers to disperse the intense heat generated by TPUs as they perform AI-related functions. There is no airflow in space, so this innovative solution is crucial for the success of orbital data centers.

Google's plans for orbital data centers are part of a larger effort to address the resource-heavy infrastructure required to power AI models on Earth. While experts caution that numerous engineering and cost efficiency challenges need to be addressed before these plans can be realized, Google is moving forward with its vision.
