Hervé Stevenin Environment Mission Operations (NEEMO 16). In September 2013, Stevenin and ESA astronaut Jean-François Clervoy slipped into the roles of Neil Armstrong and Buzz Aldrin for an underwater simulation test of Apollo 11 moonwalk tasks, organised by the Compagnie maritime d'expertises (COMEX) off the coast of Marseilles, France. They tested a COMEX-designed prototype training-spacesuit based on the Orlan adapted to simulate Moon gravity. Stevenin became an aquanaut through his participation in the NASA NEEMO 19 mission simulating undersea a space exploration mission aboard Aquarius, the world only undersea research laboratory with crewmates NASA astronaut Randy Bresnik, ESA astronaut Andreas Mogensen and
