Abstract: Exploration of small craters and craters clusters on Mars allows one to study meteoroid fragmentation details that cannot be detected in terrestrial conditions. It was suggested earlier that the description of a cluster with a scattering ellipse allows one to estimate the meteoroids' trajectory, which is connected with orbital parameters of the impactor. Independent construction of scattering ellipses and comparison with crater ejecta demonstrate the accuracy and find out some problems of this approach.
