The European Rosetta mission arrived at Comet 67P/Churyumov-Gerasimenko in August 2014 after a 10-year journey through space. Three months later, the Philae robotic lander touched down on the comet – the first probe to do so in the history of humankind. It was a fantastic scientific adventure and an exceptional spaceflight project. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) takes you on a journey to the origins of the Solar System with this exhibition app “DLR COMETS - The Rosetta mission: Journey to the origin of the Solar System”. The centrepiece of the exhibition is a model of comet 67P/Churymov-Gerasimenko based on data from Rosetta’s OSIRIS camera system, surrounded by backlit photographs of the comet and mission highlights. Additionally to the historical and technical background on comets as important building blocks of the Solar System, the Rosetta mission and its scientific achievements to date, the exhibition includes film-clips highlighting the personal stories of the men and women that made Rosetta a reality and the deep emotions evoked by involvement in the mission.
