History is making a big splash at the National Geographic Museum of Exploration in Washington, D.C., this summer. The SP-350 Denise — better known as Jacques Cousteau’s Soucoupe — defined oceanography as we know it today. Invented by Jacques and engineer Jean Mollard, this “diving saucer” allowed scientists to observe the deep sea at 400 meters for hours at a time. It launched for the first time in 1959 from the deck of Jacques’ research ship, Calypso, and its capabilities revolutionized our understanding of the ocean and what we can do to protect it. We can’t wait for you to dive deeper into the story with our full-scale replica of the Soucoupe at #TheMOE! For now, here’s a sneak peak at this deep sea icon.
