Product Description
This high-interest video documents the best observed meteor impact in history. In February 2013, a large asteroid broke apart over central Russia. Inhabitants of Chelyabinsk witnessed the impact, and the town suffered significant damage when a sound blast emitted by the fragmenting object struck the town. Nearly 1000 people were harmed by flying glass and other debris. Never before in known human history had so many people been hurt by an object from space.

Soon after the impact, dozens of high quality videos taken by dashboard cameras and cellular phones were uploaded to the Internet, offering a bonanza of data for space scientists and meteor researchers.

NOVA's Meteor Strike describes the efforts of scientists to reconstruct the properties and orbit of the Chelyabinsk meteor. It also underscores the danger that earth faces from potential meteor impacts. The space scientists came to the alarming conclusion that the Chelyabinsk impact could have been much worse, and that its potential damage was mitigated by its shallow angle of entry and fragmented stone composition.

The pdf contains a two-sided video worksheet consisting of 38 multiple choice question, along with an answer key. You will need to obtain a DVD of the video, or use the PBS Internet site or YouTube.
