As Deep Impact's impactor probe smashed into Comet Tempel 1 this week, every available observatory, on land and in space was watching to help gather as much science as possible from this $333 million mission. The Gemini North telescope, located on Hawaii's Mauna Kea successfully captured images, before and after the collision that clearly show the debris cloud moving off the comet. They also found evidence that rocky materials were exposed on the comet's surface.
