The growing problem space debris poses for Earth

Season 2024 Episode 225 | 6m 09s

From defunct satellites to rocket parts, debris from everything humans have launched into space since the 1950s is orbiting the Earth. That space junk is threatening our technology, both up there and down here. Marcus Holzinger, a professor of aerospace engineering at University of Colorado Boulder, joins Laura Barrón-López to discuss what’s at stake.
