We are a student initiative at the TU Braunschweig. We develop, build and launch experimental rockets. We already successfully participated twice in the remote formula of the European Rover Challange. Now we develop and build our own mars rover demonstrator in order to participate at the on-site formula of the European Rover Challenge in Kielce, Poland. Last but not least we are engaged in developing high altitude experiments which are deployed on our own weather balloons or are made for participating in DLR’s REXUS/BEXUS program.
