Zusammenfassung der Projektergebnisse

Stardust was the first space mission ever that returned solid material from a known object other than the Moon, namely comet Wild 2. In order to understand the chemical (inorganic as well as organic), isotopical, mineralogical, and structural properties of the cometary dust, six preliminary examination teams were constituted that had exclusive access to the Stardust samples during the first six months after the return of the spacecraft in January 2006. The principal investigator of the project, Dr. Thomas Stephan, was member of four of these teams focusing on inorganic and organic chemistry, mineralogy, and the structural properties derived from impact features. The work carried out in this study played a central role for the determination of the bulk chemical composition of Wild 2 that is practically identical to the bulk composition of the Solar System. However, individual dust grains show large heterogeneities even on a submicrometer scale. A big surprise was the finding of inner Solar System material in the cometary dust that comes from the outermost regions of the Solar System. These findings had implications for early Solar System models that need to explain large scale mixing in our Solar System 4.6 Billion years ago. Presolar grains that were expected to occur in great number in cometary dust were found to be much less abundant than in other primitive Solar System material. However, this apparent lack of presolar material can be explained by preferential destruction or mixing of these grains with normal Solar System material during capture by Stardust. Our results were instrumental for a better understanding of these processes that occur during impact of the cometary dust into the aerogel collectors and aluminum foils. Contrary to previous models, cometary material in Wild 2 is not just a mixture of primitive presolar matter. The history of cometary matter seems to be more complex. This mater represent a mixture of high-temperature minerals formed in the inner solar system, primitive presolar material, and organic matter and ice that have never seen high temperatures. More studies are needed to fully understand the properties of Wild 2 material captured by Stardust.
