NASA Comet Discoveries and Encounters

NASA commemorated a quarter-century of comet discoveries, and looked forward to future comet encounters during a symposium at the Newseum in Washington. A team of NASA scientists and academicians who study comets discussed the impact of these celestial formations on the evolution of Earth. The program is available as a large download. It also has been split into parts to make the download faster.
