Planetary Defense

We talk with CDR Leviticus Lewis, U.S. Navy (ret.), who now works with FEMA as a Program Manager for NASA's Planetary Defense Initiative. Mr. Lewis talks about the most current efforts of the Planetary Defense initiative and the launch of the DART mission to test kinetic impact on an asteroid. Planetary defense encompasses all the capabilities needed to detect the possibility of a potential asteroid or comet impact with the earth, and then either prevent the impacts or mitigate the possible effects of an impact. He also comments on the global coordination and participation of international agencies on planetary defense.
