2006 Research Report

Mars related problems include modeling of 1) high-velocity ejecta  possible martian meteorites and fragments, creating secondary craters; 2) water/ice content influence on proximal ejecta rampart craters.

Terrestrial craters: 1) numerical modeling of small craters with particular attention to a projectile deceleration and disruption in atmosphere (with an aim to estimate accurately asteroid hazard in this size range and to reconstruct impact scenario); 2) numerical modeling of the largest craters' ejecta - to compare the results with available data (e.g. the Chicxulub distal ejecta) and to estimate their influence on the Earth's climate.

Moon: 1) High-velocity ejecta modeling possible material exchange between the Moon and the Earth (lunar meteorites, He-3 anomalies); magnetic anomalies in antipodes of the largest lunar basins.
