Dr. Andrews explores how modern planetary defense blends cutting-edge detection networks, such as NASA's NEO Surveyor, with active deflection efforts like the DART mission, which successfully shifted an asteroid's orbit. He also delves into theoretical approaches, including gravity tractors and even nuclear options as last-resort strategies. While comets remain a tougher, faster-moving threat, advances in technology continue to make catastrophic impacts increasingly unlikely. Driven by a deep passion for the solar system's tangible wonders, Dr. Andrews continues to write and follow groundbreaking missions like NASA's Europa Clipper. About Dr. Robin Andrews: Dr. Robin Andrews is an experimental volcanologist, science journalist, and award-winning author whose work has appeared in Scientific American, National Geographic, The New York Times, and The Washington Post, including front-page stories in the latter two. He has frequently appeared on television programs such as Good Morning America and BBC News, and was awarded the 2022 David Perlman Award for Excellence in Science Writing by the American Geophysical Union. Robin's books include Super Volcanoes: What They Reveal about Earth and the Worlds Beyond and How to Kill an Asteroid: The Real Science of Planetary Defense, blending rigorous science with engaging storytelling. Show Highlights: (1:29) Where asteroids and comets come from and how they may pose a threat to Earth (3:11) How large asteroids have to be to cause significant city-wide or nation-wide damage (4:31) How big an asteroid has to be reach planet-killer status (5:48) How we know where asteroids are and their threat… ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/amsecast-3515150/episodes/planetary-defense-101-with-dr-robin-andrews/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/amsecast-3515150/planetary-defense-101-with-dr-robin-andrews.md` — Read the agent-friendly Markdown representation of this episode resource.
