The first link talks about crashing the probe crashing into the moon to see if they can find water molecules and get new data about the surface material of the moon. The second link shows how many people were disappointed in the non-visual results of the impact because scientists were thinking there would be an impact crater and a dust plume up to six miles long projecting out from the moon.. but that didn't happen.

And if you go to NASA's website you can see the video of it happening.

Wow, I'm glad I wasn't really looking forward to seeing it happen live. Even the video clip is nothing like what I'd have expected to see. I was thinking it would have been a fluid video, but instead it seemed to look like something made on photoshop.
