Six astronautes, participant au programme d\u2019entra\u00eenement souterrain CAVES de l\u2019ESA, ont r\u00e9cemment eu la chance de d\u00e9couvrir un nouveau type d\u2019esp\u00e8ce vivante.<\/p>\n<\/div>\n

Tous les pays envoyant des astronautes sur la Station spatiale internationale font suivre \u00e0 leurs \u00e9quipes le programme d\u2019entra\u00eenement CAVES. Cette formation a \u00e9t\u00e9 con\u00e7ue pour am\u00e9liorer l\u2019esprit d\u2019\u00e9quipe dans les conditions les plus extr\u00eames. Pendant leur s\u00e9jour de six jours dans l\u2019obscurit\u00e9 des grottes de la Sardaigne, une grande \u00eele italienne situ\u00e9e au sud de la Corse, les astronautes ont men\u00e9 plusieurs projets scientifiques, dont un li\u00e9 \u00e0 la recherche de formes de vie souterraine.<\/p>\n

Cette ann\u00e9e, avant l\u2019arriv\u00e9e des astronautes, les organisateurs de ce programme d\u2019entra\u00eenement ont observ\u00e9 de surprenants crustac\u00e9s dans l\u2019un des \u00e9tangs souterrains. (La plupart des crustac\u00e9s - comme les crabes, les crevettes et les homards - vivent dans l\u2019eau.) Les astronautes ont d\u00e9cid\u00e9 de placer pr\u00e8s de l\u2019\u00e9tang et dans d\u2019autres endroits un \u00ab app\u00e2t bien puant \u00bb, compos\u00e9 de foie et de fromage en d\u00e9composition, afin d\u2019attirer un maximum de cr\u00e9atures.<\/p>\n

Quelques jours apr\u00e8s, les astronautes ont pr\u00e9lev\u00e9 des sp\u00e9cimens des esp\u00e8ces les moins communes et les ont pr\u00e9serv\u00e9s dans l\u2019alcool afin de les ramener \u00e0 la surface. C\u2019est ainsi que l\u2019\u00e9quipe d\u2019astronautes a d\u00e9couvert une cr\u00e9ature jusqu\u2019alors inconnue.<\/p>\n

Cette minuscule forme de vie, longue d\u2019\u00e0 peine 8 mm, est une sorte de cloporte. Les cloportes, qui vivaient \u00e0 l\u2019origine dans l\u2019eau, sont les seuls crustac\u00e9s \u00e0 avoir \u00e9volu\u00e9 pour s\u2019adapter \u00e0 la vie terrestre. Curieusement, cette nouvelle esp\u00e8ce a retrouv\u00e9 la vie aquatique en revenant aux origines de son \u00e9volution.<\/p>","protected":false},"excerpt":{"rendered":"
