NDLI: NOVA: Asteroid; Doomsday or Payday? | Protecting Earth from Asteroids

Content Provider	PBS LearningMedia
Copyright Year	2014
Description	Explore how scientists are researching methods to prevent asteroids or comets from hitting Earth in this video excerpt from NOVA. In the movies, a threatening near-Earth object is typically blown to pieces. However, a kinetic impactor that changes the course of the object may be a more effective solution in the real world. Hear from a scientist who studies strategies to destroy or deflect an asteroid and watch as he and his team simulate collisions using a model asteroid made of resin and high-speed projectiles. High-speed video allows them to analyze impacts in great detail to see how the fragments behave and how the model asteroid responds.
