Can Asteroids Rock Our World? with Christina Hernández and Terik Daly

It's a beautiful night—the sky is clear, the stars are twinkling. You see a shooting star! Or is it a comet! Maybe a meteor? Whatever it is, it’s gone in an instant. But what if that whirring bit of space were headed... straight towards the Earth, not past it? Yeah, not so cute. This week, Christina Hernández and Terik Daly of NASA join Jonathan to talk about asteroids, what they’re made of, and how we could protect the planet if one came hurtling towards the place we call home.

Christina Hernández (she/her/hers) is a systems engineer at NASA’s Jet Propulsion Laboratory. She currently works on Psyche, NASA’s mission to a metal world, as a flight systems engineer. She previously spent over 6 years working on NASA’s Perseverance rover mission as a payload systems engineer. You can follow Christina on Twitter @estrellasycafe.

Dr. Terik Daly is a planetary scientist at the Johns Hopkins University Applied Physics Laboratory. He is the deputy instrument scientist for NASA’s Double Asteroid Redirection Test (DART) mission, which is the world’s first planetary defense test mission.
