Well - impactor TCM 1 went well - <0.3% error and it's on course for a nominal impact time. PI has suggested that the comet is Banana shaped and we're going to hit the end of it which looks a little triangular ohmy.gif

I want to thank tman for his work on trying to track the motion of the impactor. I have taken two of his frames, one from early on and the second to last frame, to show the motion. I have identified the location of the second to last frame in the fourth from the beginning. This shows that the nucleus rotated under the impactor so that the sub-spacecraft point moved from lower right to upper left, from those two bright deposits to the low scarp at upper left. Some of the motion I see is definitely from lower right to upper left, on average, but there are a few deviations. Still, very odd frost deposits, definitely suggesting that we will find fresher ice beneath this dark surface layer (a la Phoebe).
