ASTEX stands for a feasibility study of an exploration mission to two near-Earth asteroids. The targets should have different mineralogical constitution, more specifically one asteroid should be of ‘primitive” nature, the other one should be “evolved”. The scientific goal of such a mission is to explore the physical, geological and compositional constitution of the asteroids as planetary bodies as well as to provide information and constraints on the formation and evolution history of the objects per se and of the planetary system, here the asteroid belt, as a whole. Two aspects play an important role, i.e. the search and exploration for the origin and evolution of the primordial material for the formation of life in the solar system on one side and the understanding of the processes that have led to mineralogical differentiation of planetary embryos on the other side. The mission scenario consists of an orbiting and landing phase at each target. The immediate aims of the study are (1) to identify potential targets and to develop for selected pairs more detailed mission scenarios including the best possible propulsion systems to be used, (2) to define the scientific payload of the mission, (3) to analyse the requirements and options for the spacecraft bus and the lander system, and (4) to assess and to define requirements for the operational ground segment of the mission.This eight-months study is directed by the MPI for Solar System Research under support grant by DLR Bonn-Oberkassel and is performed in close collaboration between German scientific research institutes and industry. It is considered complementary to mission studies performed elsewhere and focussing on sample return and impact hazards and their remedy from near-Earth objects.
