NPR examines the growing buzz around orbital data centers, driven in part by Elon Musk’s announcement that SpaceX plans to put data centers into orbit to tap the unlimited solar power of space. As AI drives global data center electricity consumption toward nearly 1,000 terawatt-hours annually by 2030, the appeal of power-free computing in orbit is real — but so are the obstacles.
Replicating even a modest 100-megawatt data center in space would require a facility 500 to 1,000 times larger than the International Space Station’s solar array. Add the challenges of heat dissipation in a vacuum, laser-based data transmission between satellites, and launch costs that Google believes must drop by a factor of five before orbital data centers make financial sense, and the timeline grows murky fast.
“It seems like there’s a lot of ifs and a lot of advancements that would have to occur. No one in data center land is losing any sleep.”
– Raul Martynek, CEO, DataBank
NPR profiles DataBank’s IAD1 facility in Ashburn, Virginia — 144,000 square feet consuming around 13 megawatts of power — to illustrate the constant maintenance, upgrades, and on-site workforce that keep terrestrial data centers running, and that no orbital alternative can easily replicate.
