Overview
- Google launched a refrigerator-sized prototype called MVP on October 1, 2026, aboard SpaceX’s Transporter-18 and confirmed the satellite is returning telemetry as it begins short inference tests.
- The craft carries four Tensor Processing Units and about 1 kilowatt of solar power and will run roughly 15-minute AI inference bursts before shutting down to cool.
- The mission’s goal is to measure survivability, radiation effects, thermal limits, and telemetry performance after substantial ground testing at UC Davis showed the chips fared well under simulated radiation.
- Google plans two follow-on satellites in 2027 to test continuous operation and high-bandwidth laser links between spacecraft, and its modeling says cost parity with Earth data centers would require very large drops in launch cost and hundreds to thousands of Starship-equivalent launches.
- The test raises practical concerns for space traffic, debris, cooling in vacuum, hardware obsolescence, launch emissions, and impacts on communities and astronomy that will shape regulatory and commercial decisions going forward.
