"MOON WALK - 50 years moon landing" looks at the significance of the moon missions at the end of the 60s and beginning of the 70s for today's space research. Tanja Mohr-Westheide, impact researcher at the Museum für Naturkunde Berlin, collected the moon sample for the mission at the NASA Johnson Space Center in Houston, Texas. The sample, cast in resin, will be on loan in the exhibition until 11 October 2019. "The moon serves as a reference for researchers: its craters and rocks are an archive of impact events that occurred on Earth during the same period - but are no longer visible. Moon samples are therefore still interesting for science after decades", says Professor Kai Wünnemann, Head of the Department "Impact and meteorite research" in the research area "Evolution and Geoprocesses". The moon samples and the scientific findings of the Apollo missions provide information about the origin and development of the moon and the earth.
