Les environnements sous-marins permettent de simuler les conditions de l’exploration spatiale et offrent à la NASA un cadre pour tester du matériel, mener des recherches et préparer de futures missions dans des environnements extrêmes, tels que la Lune ou Mars. L’immersion sous l’eau recrée l’isolement, les espaces confinés et les ressources limitées auxquels les astronautes sont confrontés dans l’espace.
