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.

Teia is an application that represents the solar system using 3D models. But, unlike the rest of the applications published in the stores, the objective of this application is to show the objects that this system is composed of by teaching perceptible and localizable curiosities on the surface of the planets. What are the rilles on the Moon? And the rupes on Mercury? Does Jupiter have a pearl necklace? Is really there a face on Mars? Why does Neptune have such an intense blue color? Learn every corner of the Solar System with this great collection of features spanning a total of over 40 pages, structured and developed by experts in the Planetary Astronomy field. The models represented have been designed taking care of the maximum possible realism, from the true color of the surface of Venus, to the structure of the ring systems. In this way, you have the feeling of visiting each planet only a few thousand kilometers away. The models represented are the following: * Mercury. * Venus. * Land. * Moon. * Mars. * Jupiter. * Saturn. * Uranus. * Neptune. Application developed by Himalaya Computing and Órbita Bianca.
