In Episode 66 of Rabbit Hole of Research, Joe, Nick, Georgia, and Mary welcome Charles Blue, a science writer with over 35 years of experience in astronomy, Earth science, and science communications. Charles serves as Executive Communications Strategist for NASA’s Exploration Directorate, and has participated in tabletop exercises that simulate real government responses to potentially hazardous near-Earth objects (NEOs).
The crew digs into the difference between asteroids, comets, and NEOs, why objects approaching from the sun’s direction are nearly impossible to detect, and how impact risk changes dramatically depending on size, composition, and warning time. Charles walks through the global network of observatories tracking these threats, the communication challenges of telling the public something might be coming, and what those tabletop scenarios actually look like when the cone of uncertainty lands on the place he calls home.
From altering an asteroid's albedo, its surface reflectivity, with paint, to kinetic impactors to the politics of nuclear deflection, the crew works through what we can actually do, and how NASA’s DART mission proved that moving an asteroid isn’t just Handwavium. Charles also discusses next-generation detection, and Joe asks about the dangers of asteroid mining liability, and pulls on the Starship Troopers conspiracy thread.
The real science of planetary defense is more interesting than anything Hollywood has thrown at us.
And yes, we’re looking at you Armageddon.

We want to Hear From You (leave a comment):
1) If you knew an asteroid was on a collision course with Earth, would you want the government to tell you? Or would you rather not know?
2) DART proved we can move an asteroid, but who should have the authority to make that call? One country, the UN, everyone?
3) What’s your favorite fictional take on an asteroid or comet impact, and don’t worry about the science, they all use a healthy dose of Handwavium?
4) The Starship Troopers conspiracy, did the government let Buenos Aires happen? We want to know where you stand.
