ESA astronaut Pedro Duque looking out the viewport from his home 20 m undersea during NEEMO-22. The 22nd NASA Extreme Environment Mission Operations mission, consisting of astronauts, technicians and scientists living in 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.
