Astronaut and geophysicist Alexander Gerst spent almost a year on the ISS space station. Now he is setting off with us on new research adventures – to the extreme regions of the Earth. His goal: to document the state of our homeland in space. In Antarctica, Gerst was on the lookout for meteorites. Off the Azores, he dives into the deep sea together with marine biologist Antje Boetius. And on Spitsbergen, Gerst accompanies science teams on climate research on lonely glaciers, in ice caves and at icy heights. The astronaut’s journeys demonstrate how beautiful and diverse our world is. But they also show that we humans are putting our future at risk on this unique “Spaceship Earth”.
