Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We’ll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.

Guests:

Scott Sandford - Astrophysicist and Research Scientist at NASA’s Ames Research Center

Robin George Andrews - Science journalist, volcanologist, and author of "How to Kill an Asteroid: The Real Science of Planetary Defense"

Featuring music by Dewey Dellay and Jun Miyake
