Satellite megaconstellations will threaten space-based astronomy - Nature

Rapidly growing satellite constellations pose a substantial threat to astronomical observations, with projections indicating that future space telescopes will have more than 96% of their exposures affected by satellite trails, necessitating urgent mi…
