Alexander Gerst is a German European Space Agency astronaut and geophysicist, who was selected in 2009 to take part in space training. He was part of the International Space Station Expedition 40 and 41 from May to November 2014. Gerst returned to space on June 6, 2018, as part of Expedition 56/57.
