Query: Water delivery in the Early Solar System   As part of the national scientific network 'Pathways to Habitable Worlds' the
delivery of water onto terrestrial planets is a key question since water is
essential for the development of life as we know it. After summarizing the
state of the art we show some first results of the transport of water in the
early Solar System for scattered main belt objects. Hereby we investigate the
questions whether planetesimals and planetesimal fragments which have gained
considerable inclination due to the strong dynamical interactions in the main
belt region around 2 AU can be efficient water transporting vessels. The
Hungaria asteroid group is the best example that such scenarios are realistic.
Assuming that the gas giants and the terrestrial planets are already formed, we
monitor the collisions of scattered small bodies containing water (in the order
of a few percent) with the terrestrial planets. Thus we are able to give a
first estimate concerning the respective contribution of such bodies to the
actual water content in the crust of the Earth.
