A data center in space currently costs 13 times more to build and run than one on the ground.
Space-based clouds are often pitched as the future of green computing because of the cold environment and constant solar power. This economic analysis reveals that launch costs and spacecraft hardware are still far too high to be competitive. Specifically, the costs range from 3.4 to 13.5 times the price of terrestrial infrastructure. Even with the benefits of free cooling in the vacuum of space, the financial gap remains massive. The dream of off-world data processing is a luxury that won't make sense until rocket launches become significantly cheaper.
Orbital Data Centers: Spacecraft Constraints and Economic Viability
arXiv · 2604.27197
Orbital data centers are being evaluated as solar-powered compute constellations and relay-integrated processing platforms. Their feasibility is not set by orbital solar flux alone, but by simultaneous closure of photovoltaic generation, eclipse recharge, radiative heat rejection, sustained space-to-ground communications, utilization, replacement cadence, and delivered compute-years over finite mission life. This paper derives necessary cluster-level competitiveness conditions using delivered in
