ESA’s Matthias Maurer and Hervé Stevenin took part in NASA’s Extreme Environment Mission Operations, or NEEMO – a 16-day underwater sortie to enact a mission to Mars and test equipment for astronauts.

About 4.5 km off the coast of Florida, USA, a rotating crew of four complemented Matthias and NASA astronaut Megan McArthur who tested new techniques, operation procedures and technology.
