Hervé Stevenin, engineer ENSMA Promotion 1985, is the European Astronaut coach of the European Space Agency. He completed a mission, NEEMO 19 NASA astronauts with the aim to study the behavior of persons subject to conditions similar to those encountered in a distant spacecraft from Earth during a long stay conditions. The pleasant surprise is that he and NASA have booked students ENSMA a time slot for a half-hour videoconference live … from the bottom of the sea! Indeed, Hervé Stevenin and the astronauts were trapped for a week in an underwater laboratory (Aquarius) off Florida. Students and school staff were impressed and pleased with the exchange.
