How do you prepare for space missions on Earth? One way is to simulate an expedition into space underwater. Yesterday, six aquanauts dived almost 20 m to the sea floor where they will spend 10 days living and working below the waves.
The team taking part in NEEMO 22, the 22nd NASA Extreme Environment Mission Operations mission, consists of astronauts, technicians and scientists who are now on board he 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.
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.
The team will also assess new ESA hardware to help evacuate astronauts when on a lunar spacewalk. The Lunar Evacuation System Assembly (LESA) concept was developed and tested at ESA's astronaut centre in Cologne, Germany.
When on a sortie in space, astronauts always head outside in pairs for safety. LESA will allow one astronaut to transport a colleague in need back to base and rescue. The system was tested in ESA's neutral buoyancy facility and will now be put through an operational test during NEEMO.
Underwater and above
Space agencies are always looking for ways to prepare and train for spaceflight without leaving Earth. ESA sends astronauts underground in Sardinian caves and NASA goes underwater. Astronauts from all Space Station partners join to make the experience as realistic as possible - working efficiently and safely with a culturally diverse team is part of the package.

A strong future Science, Technology, Engineering and Math (STEM) workforce is vital to sending humans to Mars, yet a new survey commissioned by Lockheed Martin (NYSE: LMT) shows about a third of U.S. middle school and high school teachers (36 percent) see enthusiasm from their students about STEM learning. To help address these findings, today the company unveiled new resources as part of ... read more
