Testing lunar tools underwater

NASA astronaut Jessica Watkins tests ESA-developed prototypes for a set of geological sampling tools and a support trolley to be used during future missions to the Moon. This testing took place in June 2019 during NASA's NEEMO 23 mission during which ESA astronaut Samantha Cristoforetti led a crew of aquanauts living and working underwater for nine days onboard the world's only undersea habitat, Aquarius.
