Blue Dot 97: Planetary Defense

Apr 27, 2018

In this episode we talk defense. Planetary defense. From one of the worst of all possible natural diasters, an asteroid impact. Dave talks to Lindley Johnson, NASA's "Planetary Defense Officer" from HQ in Washington, Paul Chodas (an expert on calculating asteroid orbits) and Physicist Megan Bruck Syal from the Lawrence Livermore Laboratory in Pasadena. Johnson and Syal are involved in HAMMER ( Hypervelocity Asteroid Mitigation Mission for Emergency Response), a mission designed to actually deflect an asteroid on a collision course with Earth. One thing that all of our guests mentioned: "This isn't like the movie Armageddon" and while we get that, we also felt the need for a little Aerosmith in the show, and you don't want to miss a listen and enjoy while contemplating the worst of all possible natural calamities.
