Scientific paper

Comet sample temperature rises due to the adduction of mechanical energy connected with sample acquisition operations should be kept as small as possible, in order to minimize the probability of modifications of the samples chemical-physical properties. In addressing this problem, mathematical models are developed for determining the time evolution of the temperature field in the sample acquisition, together with the results obtained for different sampling techniques, comet material characteristics, drill power and penetration rate or harpoon speed of impact. Temperature rises are shown to be very significant.
