This time a year ago, Thomas Pesquet was orbiting planet Earth on board the International Space Station. As we round off 2017, France’s 10th astronaut joins FRANCE 24 for a look back on a year that, for him, was literally out of this world. Join us inside the historic cupola of the Paris Observatory for this exclusive interview with FRANCE 24's European affairs editor Catherine Nicholson. The engineer-turned-spaceman tells us about the European Space Agency mission that took him on a 127 million kilometre journey around Earth; and explains why this experience has inspired him to take up the fight against climate change. He also opens up about his scariest moment on board the ISS (clue: it involved a spacewalk).
