Abstract

On the 3. of September 2006, the SMART-1 mission is ending with an impact on the Moon. The talk will deal with the statistical lunar crater model derived from the images delivered by this spacecraft. Impact cratering is an important geological process which affects the majority of the terrestrial planets, moons and asteroids. The size and shape of the craters are determined by the velocity of the impactor and the soil conditions of the target material. In this presentation I take a statistical approach, assuming that each crater is a representation of a Gaussian random circle. This approach allows the calculation of the correlation function of the crater contours and offers access to the fractal dimension of the terrain at a certain range.
