Deep Impact Catches First Glimpse of Target Comet

smooth wombat writes "The BBC has a story, with pics and diagrams, showing the first image of comet Temple Tuttle 1 taken by the Deep Impact spacecraft. (Secondary link from Wired News) The Deep Impact spacecraft is to rendezvous with the comet on July 4th and impact the comet in an attempt to learn more about how comets are formed and possibly more insight into how the solar system was formed. A camera on the impactor will allow scientists to examine the surface of Tempel 1 in greater detail than ever before. Depending on how much dust hits the camera's lens, scientists should be able to see photos up until a second before impact. If that's the case, the photos will reveal objects as small as 8 inches in width. The photos will immediately be relayed to the main Deep Impact spacecraft and then down to Earth."

    The encounter, at roughly 23,000 mph, is expected to kick up dust and leave behind a large crater, though scientists don't know for sure just what will happen since they have never attempted anything like this before.

    I couldn't find anything in either article about the instrementation other than that they have cameras. Is that the only thing they've got? If so, then an image won't be able to do anything than generate more questions and add little insight.

      Even if there were no cameras or other instruments on board, data would be generated because the comet's orbit should be perturbed very slightly, something that would show up in future orbits.

      The data will be valuable if we are ever required to change a comet's orbit in a hurry, or even if we weren't in a hurry but knew that something would hit the earth in hundreds of years. Due to the long distances traveled, a slight change very early on expands into a much greater effect many years later. There wouldn't be a need to launch a megaton nuke against something as long as it can be prevented early on by touching it with a feather.

      That being said, a camera image can plainly tell you if you hit the target at all, and answer critical questions such as: did the object go straight through the comet without transferring any momentum? How much material was displaced? What is the size, density and composition of the dust cloud? What is the shape of the crater?

      Much of this data can analyzed later to improve the accuracy and dependability of future missions, to help decide how much more research is needed, and to improve our understanding of space debris in general.

      I work on the Shuttle and Station programs. Occasionally, we need to dump water overboard for one reason or another. It's spectacular to see from the ground, and while there are some constraints as to when it needs to occur often times we simply pick an arbitrary time period within a window to actually execute the dump.

      You can be darn sure that, given the choice, we schedule it to occur over the continental United States with the proper lighting to see it for ourselves and watch the news pick it up! If the trajectory doesn't work out, we try to give Europe a show.
