The crisis in space
Man-made "megaconstellations" could end space travel. Space actives are growing rapidly, but what is often left unmentioned is the rapid growth of ‘space junk’ around the Earth’s orbit. If this is left unchecked, thick fields of debris could pose a dangerous obstacle to the new era of space exploration that has just started. W. Robert Pearson — a fellow in the Rethinking Diplomacy Program at Duke University — and astrophysicist Benjamin L. Schmitt together explore the developing concerns, arguing that it is crucial to update the international Outer Space Treaty with rules that can create a positive environment for exploration.
