'horizons' is the name of German ESA astronaut Alexander Gerst's next mission. He takes part in expedition 56/57, his second 'research voyage' to the International Space Station ISS, in June 2018. After the Belgian ESA astronaut, Frank de Winne, Gerst is the second European as commander of the ISS. On 20 December 2018 Gerst returned together with Prokopjew and Auñón back to Earth. With the landing in Kazakhstan, the mission Horizons officially ended.
Alexander Gerst remained in orbit, at an altitude of almost 400 kilometres, for six months. The name 'Horizons' symbolises the curiosity and fascination of exploring and researching the unknown.
German universities and research institutions, German companies and DLR as a research centre contributed approximately 35 experiments to the Horizons mission. Here, the planned range of topics extends from biological and medical experiments, to research topics from the fields of (astro)-physics and material sciences. They also include technology demonstrations, an education programme for children and adolescents, and industrially or commercially-motivated applications.
