We have launched all manner of satellite and machinery into low-Earth orbit. But what goes up must come down. Most often, these items burn up in the atmosphere upon re-entry, which isn’t good for air quality or the ozone layer.

But not everything incinerates — and increasing amounts of debris are hurtling back toward Earth and landing in backyards and farm fields. Falling detritus disrupts air travel and risks collision with infrastructure and people on the ground. There are those who argue that additional regulation is required around the launching and de-orbiting of these materials.

In this episode, host Ari Daniel speaks with astronomer Samantha Lawler and Smithsonian contributing writer Dan Falk about space junk and the concern among researchers that it is becoming a growing threat to public safety.
