Sixty-six million years ago, the ultimate
catastrophe: a massive asteroid slams into
the Gulf of Mexico, blasting an enormous crater.
The impact wipes out most of the world's known
species, including the dinosaurs.
"The asteroid impact is the only global instant
catastrophe we know of.
It happened in a day."
"It caused such environmental disaster to
our planet that seventy-five percent of all
life went extinct."
But how did a local event trigger a worldwide
cataclysm, killing dinosaurs everywhere?
To find out, NOVA is following an extraordinary
expedition to drill deep into the asteroid
crater.
"It's a really big effort on the human scale.
People are just really excited about this
science."
Science that will reveal new evidence about
one of Earth's most devastating catastrophes:
the day the dinosaurs died.
