I just wrote an article for IEEE Spectrum (https://spectrum.ieee.org/planetary-defense-killer-asteroids) about my work on some big questions: Is humanity in danger from potentially deadly asteroid impacts? How can we spot them? And how can we protect ourselves?
I work at the Johns Hopkins Applied Physics Laboratory designing spacecraft that can crash themselves into asteroids to prevent them from hitting Earth.
I’ve researched asteroids for years. I was an Instrument Scientist for the Mercury Dual Imaging System (MDIS) and the Chair of the Geology Discipline Group for NASA’s MESSENGER mission. I have been on five field teams with the Antarctic Search for Meteorites (ANSMET) program. And asteroid 6899, Nancychabot, is named after me.

I am joined by Andy Rivkin, an expert in asteroids and planetary defense, to make sure we can address all your questions.
We will be here for two hours, from 1-3pm ET on June 12.
