Google to Launch Experimental Satellite to Test AI Chips in Orbit

Google is preparing to launch its first experimental satellite into low Earth orbit to test how artificial intelligence chips function beyond the atmosphere, a step toward the company's long-term ambition of running AI computing in space. The satellite, named MVP, is scheduled to lift off on October 1 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

The mission is part of a broader Google initiative called Project Suncatcher, which explores whether orbital data centers could one day supplement or replace some of the massive, energy-hungry facilities that power modern AI systems on the ground. The launch was reported by The New York Times.

MVP is not a full data center but an experimental prototype. It carries four of Google's custom tensor processing units, or TPUs, giving it roughly the computing power of a single server. Its solar panels generate about one kilowatt of electricity. The satellite is designed for one year of active operation, though it is expected to remain in orbit for up to six years before burning up in the atmosphere under Earth's gravity.

Before launch, the hardware underwent radiation testing at the Crocker Nuclear Laboratory. Using a cyclotron, engineers bombarded the chips with a dose equivalent to five years of exposure in space. The tests showed that radiation-induced errors could be corrected by rebooting the chips.

Because fans cannot operate in the vacuum of space, the team developed a passive heat conduction system. A layer of thermal interface material sits beneath the motherboard, contacting layers of aluminum and copper that channel heat to a radiator panel, which dissipates it into open space. The chips can run continuously for about 15 minutes before needing to cool down, a window sufficient to process short queries to Google's Gemini model.

The idea for the project came from Google vice president Blaise Agüera y Arcas, who proposed it roughly three years ago amid rising energy costs for AI. In May 2025, Google co-founder Sergey Brin and CEO Sundar Pichai approved the initiative. To accelerate the launch and avoid waiting until 2027, Google partnered with Planet Labs, installing its processors on an existing satellite from the partner company.

Next year, Google plans to launch a pair of satellites and is developing concepts for constellations of more than 80 spacecraft to coordinate computing in orbit. The company is also discussing with engineers the creation of a custom satellite the length of a football field. Google executives emphasize that these are long-term research efforts.
