SpaceX is preparing to launch orbital data center spacecraft as soon as next year, a move that has drawn sharp concern from the astronomical community. The satellites are designed to host computing infrastructure in low Earth orbit, enabling low-latency data processing for clients. But astronomers fear the increased satellite population and associated signals will hamper sensitive telescopes.
These orbital data centers would be larger than typical Starlink satellites and could carry antennas, heat radiators, and other equipment that reflects sunlight or emits radio frequencies. The potential for light pollution and radio interference is particularly acute for wide-field survey telescopes and radio observatories, which rely on dark, quiet skies.
The planned launch timeline—as early as 2026—signals SpaceX's rapid push into space-based cloud computing. The company has not released detailed specifications on satellite size, number, or orbit altitudes, but even a modest constellation could worsen an already strained orbital environment.
Interference from satellite megaconstellations has been a persistent issue. Astronomers note that existing Starlink satellites already leave streaks in optical images and leak radio noise. Orbital data centers, with likely greater power and thermal output, could amplify these problems.
SpaceX has not publicly addressed the astronomy concerns regarding this specific program. The company has previously worked with the National Science Foundation to reduce Starlink's reflectivity, but astronomers argue more aggressive mitigation measures are needed before deployment.
