Stock Photo - 01 October 2021, Saxony, Leipzig: At the Jesco von Puttkamer School in Leipzig, 14-year-old student Cosma (3rd from right), student Karl (3rd from left) and principal Ralf Heckel (6th from left) from Leipzig and aerospace students from the Universities of UNAQ and TEC Monterrey Curnavaca Mexico discuss a new design with carbon fibre belt drive for a moon buggy. The exchange students spend three months at the International Space Education Institute taking part in daily workshops on topics ranging from space travel, working with engineering software and study and career orientation in engineering. At the same time, they are participating in the preparation of the Leipzig team, of which Cosma is a member, for the NASA Human Exploration Roverchallenge at the US Space & Rocket Center in Huntsville/Alabama next year. At the last youth design competition for vehicles on other planets, Cosma was able to take first place with her team in 2019. Photo: Waltraud Grubitzsch/dpa-Zentralbild/ZB. - Leipzig/Saxony/Germany
