Orbital Mirrors Exceed Photochemical Retinal Limits Under Telescopes, Preprint Finds
Bará's preprint quantifies photochemical retinal and glare hazards from orbital mirrors using current safety standards. Telescopic viewing of single mirrors exceeds limits; unaided viewing mainly produces unacceptable disability glare that worsens with multiple mirrors. The analysis highlights gaps in transient-flash data and calls for empirical validation before deployment.
Key limitation is reliance on existing standards without new empirical measurements of actual mirror arrays or human-subject glare tests under realistic night-sky conditions. Stronger evidence would require controlled field trials measuring visual performance metrics during simulated multi-mirror passes and updated action spectra for photochemical damage at the relevant wavelengths.
Bará: National aviation authorities will mandate orbital-mirror glare modeling for any constellation exceeding three visible elements within three years of first commercial launch.
