Can We Stop an Asteroid? NASA's Real Planetary Defense Test

Can a spacecraft change an asteroid's path? DART tested the idea by deliberately hitting Dimorphos in 2022. This episode explains the collision, the role of escaping debris, the measured orbit changes, and why early detection matters. Dimorphos and Didymos were not on a collision course with Earth. This video explains a planetary defense experiment, not an imminent threat. Visual credits: NASA/Johns Hopkins APL; NASA's Goddard Space Flight Center.
