The AI trade has an influence drawback. Terrestrial information facilities are devouring electrical energy at charges that make grid operators nervous, and appropriate land close to energy sources is getting scarce. SpaceX and Blue Origin suppose the answer is apparent: simply put the info facilities in area.
Each firms have introduced plans to deploy satellite tv for pc constellations designed particularly to deal with AI computing workloads, powered by the one power supply that by no means runs out in orbit: the solar.
The plans: hundreds (or tens of millions) of satellites
Blue Origin’s initiative, referred to as “Venture Dawn,” goals to deploy as much as 51,600 satellites into sun-synchronous orbits between 500 and 1,800 kilometers above Earth. The orbits are chosen so the satellites keep a constant angle to daylight, which is essential when your whole energy technique relies on photo voltaic power.
SpaceX’s plan entails launching as much as a million satellites to supply 100 gigawatts of AI computing capability. For context, 100 gigawatts is roughly equal to the overall electrical energy technology capability of the UK. SpaceX filed paperwork with the FCC on February 1, 2026 outlining the initiative.
The technical actuality test
SpaceX itself seems to grasp the hole between ambition and supply. The corporate’s pre-IPO S-1 submitting explicitly acknowledges “vital technical complexity and unproven applied sciences” concerned in constructing space-based AI information facilities.
Radiation is close to the highest of the record. Pc chips in orbit face fixed bombardment from cosmic rays and photo voltaic radiation, which might corrupt information and degrade {hardware} far quicker than on Earth’s floor.
Then there’s the latency query. AI coaching workloads require large quantities of information to circulation between processors with minimal delay. Sending that information from Earth to orbit and again introduces latency that would undermine the very effectivity positive aspects these initiatives promise.
Upkeep presents one other headache. When a server fails in a terrestrial information middle, a technician walks over and swaps it out. When a satellite tv for pc fails at 1,000 kilometers altitude, you might have an costly piece of area particles.
Which brings us to the most important concern consultants have raised: area congestion. The idea is named Kessler Syndrome, named after NASA scientist Donald Kessler, who proposed in 1978 {that a} essential density of objects in low Earth orbit may set off a cascading chain of collisions. Every collision generates particles, which causes extra collisions, which generates extra particles. Finally, whole orbital bands grow to be unusable.
Including as much as a million satellites from SpaceX alone, plus 51,600 from Blue Origin, on high of the hundreds already in orbit, makes area particles administration a real concern slightly than a theoretical one.
