Yesterday, right on schedule, a man-made space satellite released a refridgerator-sized probe and aimed it on a collision-course with a comet some 83 million miles out there somewhere. The purpose of this crash was to use the resulting explosion of dust and debris to study the nature of the material on this comet. What sort of dust/dirt/ice/??? is up there? What can that information tell us about the role comets played or did not play in the formation of planets and the introduction of minerals or water to our own planet Earth.
From what I've read, it seems like the project could not have gone better and the data and pictures the team is getting from the satellite (and observations using powerful telescopes from earthlings) are quite cool.
