Google has announced the launch of Project Suncatcher, an experimental program exploring the feasibility of deploying data centers in Earth’s orbit. The concept involves launching satellite platforms equipped with Tensor Processing Units (TPUs) — purpose-built chips that will run AI computations around the clock, powered entirely by solar energy.
Travis Beals, Google’s Director of AI Paradigm Development, believes that space could eventually become the perfect environment for scaling AI infrastructure. The company has already shared preliminary findings from an internal study outlining both the technological potential and key engineering hurdles of the idea.
Solar panels and terabits per second
According to Google’s calculations, orbital photovoltaic systems could generate energy up to eight times more efficiently than ground-based solar panels. Yet the real bottleneck lies in creating ultra-high-speed data links between satellites. To compete with Earth-based data centers, the orbital networks would need to achieve tens of terabits per second in bandwidth — a goal that requires dense constellations of satellites positioned less than a kilometer apart.
Radiation is another unavoidable problem. Google says its new Trillium TPU processors have undergone radiation-resistance tests and proved capable of enduring exposure equivalent to five years of continuous operation in orbit without critical hardware failures.
The economics of space computing
For now, building a data center in space is an expensive and ambitious undertaking. However, Google analysts predict that by the mid-2030s, the operational costs of orbital computing systems could become comparable to those of conventional Earth-based data centers.
The first practical step is planned for 2027, when Google and Planet will launch a joint experimental mission to test satellites equipped with onboard AI computing hardware in low Earth orbit. The mission aims to confirm whether orbital AI data centers are a realistic goal — or just a stellar idea that belongs on paper for now.
