You may begin this topic wondering why studying minor members of the Solar System is worthwhile. Why would anyone want to devote their career to these chunks of ice and rock? To learn more about how and why NASA examines comets, view the video Why Study Comets? from eMediaVA℠.

After viewing the video, consider the following question: do you think it is important to study comets and the history of the Solar System? Post your responses to these questions in the discussions area. Then, return to the topic several times over the next few days to read your coursemates’ posts.
