Don’t Look Up: How NASA is getting ready for killer asteroids

Guest: Michael Daly, professor of space science and research chair in planetary science at York University

“Don’t Look Up” is the latest film to join the killer-asteroid-threatens-the-Earth genre of films. While that narrative has been the basis of plenty of science fiction, it is a potentially real scenario that NASA scientists are thinking about. In November, the space agency launched its first planetary protection mission called the NASA Double Asteroid Redirection Test (DART). DART will hit an asteroid and then measure the effects of that collision. Will it knock it off course? If so, we may have a new tool to deal with wayward space rocks that are looking for trouble with planet Earth.
