It is a common occurrence for extraterrestrial bodies to impact with planets in the Solar System. The inner planets are most at risk of impact from bodies that lie in the Asteroid Belt between Mars and Jupiter. In this program, students will see how we are preparing our planet for a possible impact and how we are using spacecraft to learn more about the asteroids.
