NASA: Half‑Million Planned LEO Satellites Could Contaminate Nearly All Space‑Telescope Images
A NASA study quantifies how exponential growth of low‑Earth‑orbit constellations — with over 500,000 satellites projected by the late 2030s — will generate pervasive optical "light pollution" that could contaminate or severely degrade images from Hubble and other space telescopes. Simulations indicate almost all future observations may be affected.
