AI Satellites: Global Tech Race Demands 300 GW Power Grid
AI satellites need 300-500 GW, requiring millions of units, new cooling tech
The race to power artificial intelligence is about to get galactic, and astronomically complex. Tech giants are confronting a staggering infrastructure challenge that could redefine computing's physical boundaries: building millions of high-performance satellites capable of supporting massive AI computational demands.
The scale is mind-bending. We're not talking about incremental improvements, but a fundamental reimagining of global computing infrastructure that would stretch technological capabilities to their absolute limits.
Powering these AI satellite networks won't be a simple engineering task. The proposed system would require an unusual energy footprint: between 300 and 500 gigawatts of continuous power. To put that into perspective, this is more electricity than many entire countries currently generate.
Companies like Blue Origin are already diving deep into the technological feasibility. Jeff Bezos's team has been quietly studying this challenge for over a year, recognizing that the next frontier of AI might literally be above our heads, in orbit.
In this model, 300 to 500 gigawatts would require a fleet of millions of high-performance satellites--a logistical and financial feat far beyond today's capabilities. Blue Origin's team has also been studying the necessary technology for over a year. Founder Jeff Bezos sees the main advantage in unlimited solar energy but expects it will take up to 20 years for orbital data centers to become cheaper than terrestrial facilities.
Google is already pursuing a concrete timeline in cooperation with satellite operator Planet Labs. As part of Project "Suncatcher," two test satellites equipped with Google's Tensor Processing Units (TPUs) are scheduled to launch in early 2027. Beals described the project as a "moonshot." Scaling requires massive constellations Google's approach differs from monolithic space stations.
Instead of massive single structures, researchers propose swarms--constellations of smaller satellites. To replicate the capacity of a terrestrial gigawatt data center, Beals says 10,000 satellites of the 100-kilowatt class would be necessary. This likely corresponds to the power generated by SpaceX's new Starlink v3 satellites.
The system design calls for these satellites to fly in a "dawn-dusk" orbit to maximize solar exposure. According to the Google paper, solar modules in this orbit receive about eight times more energy per year than at an average location on Earth. The biggest challenge, however, isn't generating energy--it's communication between the computing units.
In terrestrial data centers, AI chips like Google's TPUs connect via extremely high-bandwidth fiber optic cables. To achieve the required data rates of several terabits per second, the satellites must fly extremely close together.
The satellite AI infrastructure challenge reveals staggering technological hurdles. Powering orbital data centers will demand an unusual scale of engineering, with millions of high-performance satellites required to generate 300-500 gigawatts.
Blue Origin's team has been quietly investigating these complex requirements for over a year. Founder Jeff Bezos recognizes the potential of unlimited solar energy but remains pragmatic about the timeline.
Current capabilities fall dramatically short of this ambitious vision. The logistical and financial barriers are immense, suggesting a multi-decade transformation rather than an immediate breakthrough.
Google's active involvement hints at serious industry momentum. Still, the path to orbital data centers remains uncertain and will likely require radical ideas in cooling, power generation, and satellite design.
The astronomical scale of this challenge, millions of units and hundreds of gigawatts, underscores how far technology must evolve. Bezos's estimate of 20 years suggests patience will be important in realizing this orbital computing dream.
