ESA astronaut Samantha Cristoforetti with the crew of NASA's NEEMO23 mission.
Led by Samantha, the international crew lived and worked at the world's only undersea research station, Aquarius.
Located almost 19 m below the surface of the ocean, near Key Largo Florida, USA, Aquarius is an ideal environment to test concepts for future missions to the Moon and Mars, simulate spacewalks and carry out marine science under the guidance of Florida International University’s marine science department.
