For more than 20 years, ESA astronauts have joined other crew members on board the International Space Station. More than 240 people have lived and worked on the orbital outpost, carrying our essential research to advance our scientific knowledge in space, but also on Earth. In this special programme recorded for the 20th anniversary of the station, join the very first European astronaut on board Umberto Guidoni, together with Tim Peake, Thomas Pesquet and many others, as they reflect on the station’s remarkable achievements. Watch them recall the best moments of their time on board, including filming strikes from thunderstorms on Earth from the ISS cupola or even dressing up for Halloween. Finally, they share their thoughts on what space exploration might look like in the next 20 years.
