1 PTScientists GmbH: Mission to the Moon and the return to Apollo 17 Confidential & Proprietary First private mission to Involve “non- land on the Moon traditional” partners Conduct scientific Carry out tech experiments on the demonstration for Moon lunar-surface comms Key technology and mission partners Science and research partners Partnerships and cooperations Space belongs to everyone 6 The Core Technology With our key technological partners Audi, Vodafone and ALINA Audi lunar quattro the support of the European space agency ESA and the German space agency DLR, we developed the space-ready Audi lunar quattro rover and the ALINA spacecraft. ALINA is the autonomous landing and The Audi lunar quattro rover will deploy navigation module capable of and operate a series of technological delivering 1000 kg of payload to the payloads to demonstrate and explore lunar surface. Given it’s modular design new ways to shortcut space exploration. ALINA is compatible with all major launch providers.
