- Аннотация: The surfaces of airless bodies like Mercury undergo processes of gardening, due to the direct and continuous exposition of the regolith to the solar and cosmic radiation. The long exposure to the meteoritic and to the energetic ion bombardments causes deep changes in the surface features. Eventually, to have a real knowledge of the body, it would be necessary to study the layers below the exposed surface, down to at least tens of meters. The present mission idea consists in launching a massive and high velocity projectile, able to volatilize an adequate surface volume and generate a crater of up to a hundred meters. The projectile should be built of a special alloy that would be easily distinguishable from the one of the planet surface. This artificial impact would allow the investigations of the underlying surface layers and composition.Two mission scenarios will be presented, one of them allowing an arrival during BepiColombo’s nominal mission.
