Google to launch prototype satellite testing AI chips in low-Earth orbit
Google will send a prototype satellite carrying its Tensor Processing Units into low Earth orbit next week to assess AI hardware performance in space.
Alphabet's Google is set to launch its first in-orbit test under Project Suncatcher, deploying a prototype satellite equipped with Tensor Processing Units next week. The payload will ride on SpaceX's Transporter-18 rideshare launch, in partnership with Planet Labs, to collect data on the chips' resilience to launch stresses, space radiation and temperature extremes in low Earth orbit. Google will also examine a cooling solution that combines heat pipes with radiators, addressing the lack of airflow in vacuum.
Prior testing of the TPUs running AI workloads occurred at the University of California, Davis, but real-space conditions are required for validation. Experts caution that commercial space-based AI data centers remain years away due to high launch costs and engineering challenges. This initial mission aims to identify potential failure points, with plans for two additional satellites in 2027 to test high-bandwidth laser links for future computing clusters.
Why it matters
Proving AI chips can work in space may enable orbital data centers that sidestep Earth's energy constraints.
