Orbital AI Satellite Test
Google plans to launch its first orbital AI test satellite aboard a SpaceX rocket.

Key Points
1
The prototype’s solar panels will provide about one kilowatt of power—roughly enough to run a microwave or hair dryer—and Google accelerated the test by installing its chips in a Planet Labs satellite already under construction.
2
The satellite is intended to answer simple AI queries; its four TPUs are described as having computing power roughly equivalent to a single data-center server.
3
Before launch, the refrigerator-sized satellite passed a vibration test designed to check whether its chips and components could withstand the shaking of a rocket journey. Google executive James Manyika called the result “great,” while saying he remained curious about how the satellite would fare in space.

Google’s proposed dawn-dusk, sun-synchronous orbit would keep the satellites in near-constant sunlight; the company says that configuration could make their solar panels up to eight times as productive as ground-based solar installations.
Google is launching its first orbital AI satellite on October 1, 2026, aboard a SpaceX Falcon 9 from Vandenberg Space Force Base in California. Google calls the refrigerator-sized test satellite, built with Planet Labs, part of Project Suncatcher—an ambitious bid to see if AI computing can work in space. The spacecraft carries four of Google's custom Tensor Processing Units and represents one of the first attempts by a major tech company to run live AI queries from orbit.
The satellite will generate about one kilowatt of power—enough to run a hair dryer—and can operate for roughly 15 minutes before its chips overheat and shut down. Google executives stressed this is purely experimental. Senior VP James Manyika said plainly: 'We don't expect, to be perfectly frank, that we'll have anything usefully operational in the next few years.' The real payoff may not arrive until the mid-2030s, when solar-powered orbital clusters could help reduce pressure on Earth's power grids, water supplies, and land use.
Why Google Is Racing to Put Data Centers in Space
U.S. data centers now consume 4 to 5 percent of the country's electricity, according to research. That share is expected to jump to 17 percent by 2030 as AI systems like ChatGPT and Gemini demand more computing power. Ground-based data centers face a crushing problem: they need massive amounts of water for cooling, require huge plots of land, and strain local power grids. Some communities are already pushing back against new data center construction.
Orbital solar panels never face darkness in a sun-synchronous orbit—the path Google plans to use. This configuration makes the panels up to eight times more productive than ground-based solar installations. No water cooling needed. No land footprint. Google believes satellites in continuous sunlight could eventually help hospitals, universities, and tech companies get computing power without adding load to struggling power networks.
A Refrigerator in Space With Major Heat Problems
Google's test satellite is tiny. Its four TPUs deliver roughly the same computing power as a single ground-based server. Before launch, the spacecraft passed a brutal vibration test in Google's San Francisco lab—shaking to simulate the forces of a rocket ride. James Manyika called the results 'great,' but warned that space is a far harsher environment than any lab.
Thermal management is the killer problem. Travis Beals, the senior director running Project Suncatcher, revealed that the TPUs can run for only about 15 minutes before they generate too much heat. Then the chips must shut down and radiate that heat into space over the next 45 minutes or so. In a real orbital data center cluster, engineers would need to solve radiation shielding, power distribution, and heat dissipation on a scale never attempted before in space.
The Long Road From One Satellite to Thousands
Success on October 1 would be just the first step. Google plans to launch two larger prototype satellites in 2027 with optical laser links—allowing satellites to beam data to each other at high speed. By the mid-2030s, the company envisions clusters of 81 satellites flying in tight formation, each kept in continuous sunlight. Theoretically, a cluster of 10,000 satellites could match the computing power of a single one-gigawatt terrestrial data center.
But Brandon Lucia, a professor of electrical engineering at Carnegie Mellon University, cautioned: 'Expanding from one satellite to a vast network of them that operate like a giant data center will take years and enormous funds.' Launch costs must also plummet—Google estimates orbital compute won't beat Earth-based data centers on cost until around the mid-2030s, assuming SpaceX and other providers can drop launch prices to roughly $200 per kilogram.
Competitors and Critics Are Watching Closely
Google is not alone. Blue Origin and SpaceX have both proposed orbital computing architectures. Yet Jeff Bezos has suggested orbital data centers may not beat traditional ones on price for at least 20 years. Critics point out that orbital constellations raise serious concerns: space debris collisions, rocket launch pollution, and the risk of atmospheric ozone damage from re-entering satellites.
Environmental advocates and aerospace engineers worry that moving data centers to space doesn't eliminate harm—it simply shifts it. Launch emissions, orbital debris, and the cost of maintaining thousands of satellites could prove prohibitively expensive and risky. Google frames Project Suncatcher as a sustainable solution; skeptics see it as a bet-the-farm experiment with uncertain payoffs and real planetary risks.
