In the NASA presentation of the results of the Stardust spacecraft flyby of the nucleus of Comet Tempel, images were presented in which the results of the bombardment of the comet in July 2005 can be seen. My expressed conjecture about the pattern of the debris was not supported. In the high resolution images, which were not released to the internet before the press conference, the scientists were able to detect a small crater on the order of 150 km in diameter. During the time since the collision with the impactor, the edges of the crater appear indistinct and more smoothed out. Along with other changes in the outward appearance of the comet’s nucleus, we can say that it consists of very fragile material which, by the way, supports the current model of the structure of a comet nucleus.
