Scientists raise concerns over SpaceX's proposal to launch one million satellites, citing risks to night sky, space access, and atmosphere

Summary

Scientists are raising alarms about SpaceX's proposal to launch up to one million satellites into Earth orbit. The concerns center on three major areas: the loss of the natural night sky due to increased light pollution and satellite visibility, the risk of overcrowding space and creating debris that could limit future access to orbit, and the environmental impact on Earth's atmosphere from satellite launches and re-entries. With roughly 16,000 satellites currently orbiting Earth (14,000 active), a million new satellites would represent a massive escalation, and researchers warn that humanity's tendency toward short-term thinking is preventing proper consideration of these long-term consequences.
