Dr Alexander Gerst
“The moon is like our eighth continent; it’s still almost virgin territory,” says Alexander Gerst. At the European Space Agency (ESA), the 50-year-old heads a department that supports future missions to the moon. In 2014 and 2018, Gerst took part in long-term missions of the International Space Station (ISS), spending a total of one year in space. He had been fascinated by expeditions even as a student of geophysics: he travelled from Karlsruhe to the Antarctic to undertake vulcanology research and went to New Zealand on a DAAD scholarship. From space, he witnessed areas on Earth that were stricken by drought or had been cleared of rainforest – ever since, he has been a tireless campaigner for conservation and climate action. ―
