One of the expectations of ramming a space probe into a comet was to be able to see the resulting crater. The Deep Impact collider was released and the Deep Impact probe continued on from a distance to record the impact. What it saw was a blast much larger than expected and was so large that direct visual observance of the resulting crater became impossible. However, the same thing which kept us from seeing some of these results is the same plume of ejected material that has told us that more about this comet’s composition and how the surface materials are held together quite weakly.
