Google confirms its AI chips are working in orbit after Project Suncatcher test launch
The first Suncatcher satellite carries four Trillium TPUs and is the first space validation of Google's AI hardware
Google put a data center server’s worth of AI chips on a satellite and sent it to orbit. According to the company, the chips are working as intended.
The satellite, called MVP, is the first hardware flight test under Project Suncatcher. That is Google’s long-term bet that the best place to run AI might eventually be above the atmosphere, where sunlight is plentiful and the neighbors don’t complain about power bills.
What Google actually launched
MVP went up on October 1, 2026, aboard a SpaceX Falcon 9 as part of the Transporter-18 rideshare mission.
The spacecraft is roughly the size of a refrigerator. Inside are four Tensor Processing Units from Google’s Trillium generation.
Together, the four chips deliver computing capacity equivalent to one data center server. Solar panels on the satellite generate approximately 1 kW of power to keep them running.
After launch, Google confirmed the satellite is operating as designed. That makes this the first validation of the company’s AI hardware performing in space.
The 15-minute workday
MVP runs AI workloads in sessions of roughly 15 minutes before it has to shut down for cooling.

Heat is the quiet villain of space computing. On Earth, data centers dump heat into air or water. In a vacuum, there is no air to carry warmth away, so a hot chip has fewer ways to cool off.
Before the launch, Google’s teams ran extensive ground testing. At UC Davis, they exposed the hardware to radiation simulations that mimicked more than five years of space exposure.
Radiation matters because charged particles in orbit can flip bits and corrupt computations.
The team also ran vibration tests that simulated launch conditions.
Why Google wants data centers in orbit
Suncatcher was announced in late 2025 with a straightforward pitch. AI needs enormous amounts of electricity, and the sun produces plenty of it.
In low Earth orbit, solar panels could potentially yield up to eight times the power they produce on the ground.
Google is careful not to oversell it. The company has no immediate plans for operational orbital data centers, citing significant technological hurdles that remain unsolved.
Follow-on missions are planned for 2027. Those tests are expected to explore additional technologies, including laser communication links between satellites.
