"Opening worlds - sharing knowledge" was the motto of the event, where the initiative presented itself to the visitors from noon until the evening.

Here, knowledge transfer took place in a playful way: Not only adults, but even the youngest visitors were able to interactively gain insights into research on the exploration of Mars. They programmed small robots themselves using color codes and sent them across a Martian surface around a 3D model of the MaMBA habitat.

Professor Marc Avila, spokesman of the initiative, answered the questions of the visitors at the "Ask a Scientist" event and was pleased about the large number of visitors on the subject of Mars: "The visitors are very interested in it," said the scientist. "And many interesting questions can be answered in direct conversation."
