NASA Planetary Defense Officer Lindley Johnson was among speakers at an Oct. 25, 2016, NASA/FEMA tabletop exercise in El Segundo, California, simulating emergency response to a hypothetical future asteroid impact. Regular exercises like this facilitate a strong working relationship between the asteroid science community and emergency managers. (The Aerospace Corporation)
