A Neemo aquanaut with jetpack used to move underwater.
Neemo missions train astronauts for life in space. Living and working in an underwater base is similar to life on a space station. During a 12-day mission, ESA astronaut Tim Peake and six crewmates lived in cramped conditions, performed ‘waterwalks’ and had to solve problems as a team to test equipment and techniques for future space exploration.
The underwater base is almost 20 m under the sea off the coast of Florida.
