| Zusammenfassung: | Despite their global importance, little is known about the few existing examplesofimpacts into marine environments and icy targets. Theyareamong the least understood and studied parts of impact crater geology The icy impacts are also of great importance in understanding the developments of the outer planets and their satellitessuch asMars or Europa. Furthermore, the impact mechanisms, crater formation and collapse, melt production and the ejecta distribution arescarcely known for impact on targets other than the "classical" solid silicates of the continental crust.The reaction of water and ice to impacts clearly deserves a more thorough study. The understanding of impact effects and consequences in the case of aqueous hits, soft sediments and icy targets have not been thoroughly explored andcomprise the main focus of this book. Anumber of papers in the field of hypervelocity impacts on ice are included. These cover a review of available literature in the field of laboratory studies of such impacts, large impact structures on Titan, predicting impact cratering on a comet nucleus, and a novel report on thesurvival of bacteria fired at hypervelocity into icy surfaces. This latter paper is concerned with astrobiology and in particular Panspermia (natural migration of life through space).
