SpaceX Satellites Threaten Stargazing Future
13 Jun
Summary
- SpaceX plans orbital data centers launching by 2027.
- Astronomers fear massive light pollution from new satellites.
- Millions of satellites could make the night sky as bright as a half-moon.

SpaceX is set to launch its first orbital data center satellites, known as AI1, potentially starting in 2027. These planned spacecraft will be substantial in size, measuring 70 meters long and 20 meters tall when deployed, generating significant power for onboard computing. SpaceX aims to streamline production for these AI satellites, differing from Starlink's design by utilizing laser links and extensive solar arrays rather than complex antennas. Construction for these satellites is slated to occur in Bastrop, Texas.
Astronomers are voicing serious concerns about the impact of SpaceX's expanding satellite constellations, including the upcoming data centers and larger Starlink versions. They warn that the projected brightness and sheer number of these satellites could create continuous "bright lanes" in the night sky. This escalating skyglow is expected to hinder optical observations, with potential sky brightness levels comparable to a half-moon, which could preclude many scientific programs for ground-based observatories and impact time-domain astronomy.
