Google has taken an early step toward its vision of computing infrastructure in space by running an artificial intelligence model aboard a satellite. On October 30, the company said it had received a response from orbit generated by Gemma 4 using a tensor processing unit, or TPU, designed for data-center workloads.
The satellite was built in collaboration with Planet and launched on October 1 on a SpaceX mission. It forms part of Project Suncatcher, Google’s research effort into distributed computing systems in orbit. The demonstration was deliberately limited: researchers sent an instruction asking the model to write a haiku about being in space, then received the result through a communication window with a ground station.
The response arrived while the satellite was passing near Svalbard, Norway. Translated from English, the three-line poem referred to the blue Earth below, data flowing silently and starlight powering the processor. The significance of the test was not the poem itself, but the ability to process the request aboard the satellite and send the result back to Earth.
The prototype contains four TPUs, although it can use only one at a time and for short periods of around 20 minutes, according to TechCrunch. That makes it a test platform rather than a functioning orbital data center. Google introduced its TPU processors in 2016 after using them internally since 2015 to accelerate artificial-intelligence calculations.
AI has already been used in orbit. The European Space Agency’s Φsat-1 mission used artificial intelligence in 2020 to filter cloud-covered Earth images before transmission. Starcloud also launched a satellite with an NVIDIA H100 GPU in November 2025 and later announced that it had run Google’s Gemma model onboard. Google’s current claim is more specific: obtaining a result from a data-center-class TPU operating in space.
Project Suncatcher’s longer-term goal is to link satellites equipped with processors through optical connections so they can work together on AI tasks. Google estimates that, in certain orbits, near-continuous exposure to sunlight could allow solar panels to generate up to eight times the electricity of equivalent panels on Earth. The company has not yet demonstrated that such an infrastructure would be practical at large scale.
Space also creates engineering problems that do not exist in the same form on Earth. In a vacuum, there is no air to carry heat away from processors, so Google is investigating thermal pipes and radiators and has tested them in vacuum chambers. Radiation can also affect electronic circuits, prompting additional ground-based testing. The company still needs to assess how its hardware performs over longer periods and whether deployment costs would be sustainable.
After the initial haiku, the researchers tested other space-themed poems and prompts intended to check the satellite’s technical status. They are now preparing experiments on how the TPUs withstand thermal and radiation stress while operating in orbit. The next announced objective is to test two interconnected satellites in 2027, providing a way to study how multiple orbital computing systems could cooperate.
