Google is preparing to place its own AI chips into orbit for the first time, selecting SpaceX as the launch provider for its initial in-orbit test of Project Suncatcher. The mission, scheduled for October 1, marks a significant step in the race to determine whether space can host large-scale artificial intelligence computing.
What Happened
The satellite, designated MVP, is approximately the size of a refrigerator and will fly on SpaceX’s Transporter-18 rideshare mission. It carries four of Google’s Tensor Processing Units (TPUs), the same chips utilized in the company’s ground-based data centers. While Google originally planned to launch two custom satellites in 2027, it accelerated the timeline by integrating its chips into this existing platform. The MVP’s solar panels supply about one kilowatt of power, and Google intends to run Gemini models on the TPUs in bursts of roughly 15 minutes. After each burst, the chips will shut down to allow radiators to shed heat.
Why It Matters
This launch represents the first real test of Google’s hardware, riding on a rocket from the company with the most aggressive timeline in the orbital compute field. SpaceX’s own program is built around the AI1 satellite, a structure derived from Starlink V3 hardware designed for 150 kW of peak compute—about 150 times the power MVP will draw. SpaceX is constructing a Gigasat factory in Bastrop, Texas, targeting an annualized rate of about 1 GW of space compute by the end of 2027. In contrast, Google has been more cautious, estimating that launch prices need to fall below $200 per kilogram for orbital data centers to compete with ground facilities on energy cost, a threshold it believes could be reached in the mid-2030s. Google holds a stake of roughly 6% in SpaceX, and the two companies have been in talks regarding a larger launch deal since May.
The Bottom Line
Google’s Project Suncatcher is moving from research to in-orbit validation with a SpaceX launch, testing TPUs under launch vibration and radiation conditions that exceeded five-year mission requirements. While SpaceX pushes for massive orbital compute infrastructure, Google views this as a long-term project rather than an immediate product, highlighting the divergent strategies of the two industry giants.
