Bill Todd is in charge of the design and development of the vessel’s operational functions. Program Manager for Exploration Analogs at NASA Johnson Space Center and a specialist engineer for many years in astronaut training at NASA, Bill Todd trained most of the crews who flew with the American Space Shuttle. Passionate about the similarities between space and the underwater world, he created the NEEMO (NASA Extreme Environment Mission Operations) program, a special program to train astronauts under the sea, in the Aquarius underwater habitat, off the coast of Florida. In particular, he developed many « man to machine » operational concepts using underwater robotic means to recreate conditions similar to those encountered in space. He continues his research based on exploratory procedures and human behavior in confined and extreme environments.
