Google Tests Tensor Processing Units in Space with Prototype Satellite Launch

Google has launched a prototype satellite into orbit to test its Tensor Processing Units (TPUs) in space. The satellite, carrying four Google TPUs, was launched aboard SpaceX's Transporter-18 rideshare mission on Thursday.

According to Google, the launch marks the first step of Project Suncatcher, a long-term research project conducted with Planet Labs PBC. The goal is to explore whether scalable machine learning infrastructure can be hosted in space.

Over the coming weeks, Google will collect data on how its TPUs handle physical stress, radiation, and thermal extremes in space. This data will help refine future designs for satellite-based AI infrastructure.
