ESA astronauts Samantha Cristoforetti and Matthias Maurer joined Chinese astronauts earlier this month for nine days of sea survival training off China’s coastal city of Yantai.

This is the first time ESA astronauts have trained in China and stems from the 2015 agreement to boost collaboration between ESA and China Manned Space Agency, with the goal of flying European astronauts on the Chinese space station from 2022.

This video, filmed by the Astronaut Center of China, shows the first joint training, with interviews of ESA participants in English, French, German, Italian and Spanish.
