Cependant, pour Timothy Peake et ses \u00e9quipiers de l\u2019ESA, le contact avec l'oc\u00e9an n'est qu'un d\u00e9but. Hier, ils ont ralli\u00e9 une base sous-marine situ\u00e9e au large de la Floride. Ils y resteront pendant 10 jours.<\/p>\n<\/div>\n<p>Les missions NEEMO pr\u00e9parent les astronautes \u00e0 vivre dans l\u2019espace. Les conditions de vie dans une base sous-marine sont similaires \u00e0 celles des stations spatiales. Pendant leur mission de 10 jours, Tim et ses six \u00e9quipiers vont vivre \u00e0 l\u2019\u00e9troit, effectuer des sorties extra-v\u00e9hiculaires dans l'eau et travailler en \u00e9quipe.<\/p>\n<p>\u00c0 20 m\u00e8tres sous l'eau, les aquanautes vont subir une pression 2,5 fois plus \u00e9lev\u00e9e qu\u2019au niveau de la mer.<\/p>\n<p>En raison de la profondeur, les aquanautes ne pourront pas remonter \u00e0 la surface sans paliers de d\u00e9compression.
