The 22nd NASA Extreme Environment Mission Operations (NEEMO) mission is underway, an underwater analog exercise to train for spaceflight without leaving Earth.

Six aquanauts took a dive of some 65 feet (20 meters) to the sea floor where they will spend 10 days living and working below the waves. They are now on board the Aquarius underwater habitat off the coast of Florida.

The habitat acts as a makeshift “space base” for the aquanauts to make regular “waterwalks” in full scuba gear and, by adjusting their buoyancy, they can simulate the gravity levels found on the Moon, Mars or asteroids.

Exploration tasks

NASA astronaut Kjell Lindgren will be commander for this mission that will focus on exploration spacewalks as well as tasks based on the International Space Station. He is joined by ESA astronaut Pedro Duque, planetary scientist Trevor Gradd and research scientist Dom D’Agostino, along with two support technicians.
