Planetary Defense Spacecraft Hits Asteroid

A spacecraft sent by NASA has successfully hit a football stadium-sized asteroid in hopes of altering the asteroid’s path through space. The giant asteroid was not a threat to Earth, but from this mission, scientists can learn how to best protect the Earth from any future asteroids that might be headed toward it. Listen to hear scientists' reactions as the spacecraft hit the asteroid, find out what the asteroid looked like, and learn how space telescopes will help scientists learn more from the mission.
