Dr. Nancy Chabot returns to the show to talk about the DART mission, which changed the orbit of an asteroid moon. This was the first demonstration of asteroid deflection technology. She explains how the mission worked, what scientists are discovering, and why a small nudge is all you need when it comes to moving an asteroid out of Earth's way.
