CNN's John Sutter talks about the films Armageddon and Deep Impact. He says NASA has been working on a plan to move an asteroid that could hit Earth. The space agency is also involved in Dart, which would send a small spacecraft into collision course with it. "It's easy to sit on planet Earth and say, well, I saw Armageddon and I think you all could do better"
