Live Q&A with NASA Planetary Defender

NASA planetary defender Dr. Kelly Fast has a hard and fast rule: “Find asteroids before they find us.” Working in NASA’s Planetary Defense Coordination Office, Kelly is helping send the #DARTMission to test “nudging” an asteroid in space. DART, short for Double Asteroid Redirection Test, is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous near-Earth object. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space. NOTE: the target asteroid is currently not a threat to Earth.
