"COOL COMETS"

Comets are so cool, they're actually icy! As these cosmic snowballs approach the Sun, they turn into the beautiful celestial bodies we can see from Earth. Now, for the first time ever, a hi-te ch NASA mission will capture comet dust samples and bring them back to Earth. The samples will give us new information about comets and help us understand the origins of our solar system. Take a journey with NASA into space as we explore the mysteries of comets and the secrets of our distant past.

This 30-minute simulcast is now available as three Quicktime movies. A Quicktime 3.0 player is required to run the movies.
