Apr\u00e8s son voyage immobile vers la plan\u00e8te Mars, l’astrobiologiste fran\u00e7ais Cyprien Verseux va passer un an sur la base Concordia en Antarctique.<\/strong><\/p>\n

Si vous vous int\u00e9ressez aux projets de bases habit\u00e9es permanentes sur la plan\u00e8te Mars<\/a>, le nom de Cyprien Verseux vous dit forc\u00e9ment quelque chose. Cet astrobiologiste fran\u00e7ais m\u00e8ne des recherches autour des\u00a0micro-organismes capables de transformer les ressources naturellement pr\u00e9sentes sur la Plan\u00e8te rouge<\/a> en produits n\u00e9cessaires \u00e0 la survie humaine.<\/p>\n

\"\"<\/a>
Cyprien Verseux est arriv\u00e9 pour un hivernage d’un an sur la base Concordia en Antarctique.<\/figcaption><\/figure>\n

Il a fait partie il y a deux ans de la mission HI-SEAS<\/a> IV (Hawaii Space Exploration Analog and Simulation<\/em>), un programme de simulation de la vie dans un habitat sur Mars conduit par l\u2019Universit\u00e9 d’Hawa\u00ef<\/a> et la NASA<\/a> : avec cinq autres jeunes scientifiques, il s’\u00e9tait enferm\u00e9 pendant douze mois dans un d\u00f4me pour vivre dans les m\u00eames conditions qu’un voyage sur Mars.<\/p>\n

\"\"<\/a><\/p>\n

Une aventure que Cyprien Verseux raconte dans son livre Vivre sur Mars, 365 jours pour tester la vie sur la Plan\u00e8te rouge<\/em>.\u00a0 Cette fois l’astrobiologiste a d\u00e9laiss\u00e9 les pentes ensoleill\u00e9es du Mauna Loa \u00e0 Hawaii pour un endroit beaucoup moins hospitalier : Concordia, la base scientifique la plus isol\u00e9e du monde.<\/p>\n

Cette base, qui se situe en Antarctique, d\u00e9pend des instituts polaires fran\u00e7ais<\/a> et italien et accueille des scientifiques depuis 23 ans. Ils viennent y \u00e9tudier\u00a0la glaciologie, la physique de l’atmosph\u00e8re, le g\u00e9omagn\u00e9tisme, la sismologie, la biologie humaine ou encore y faire des observations astronomiques de grande qualit\u00e9 (pas de pollution lumineuse<\/a>, une longue nuit de 3 mois et un tr\u00e8s faible taux d’humidit\u00e9).<\/p>\n

M\u00eame si pour cette mission l’astrobiologiste va se faire glaciologue (il \u00e9tudiera l’\u00e9volution du climat), sa pr\u00e9sence \u00e0 Concordia le replonge dans son exp\u00e9rience hawaiienne. Car Concordia, c’est un peu Mars la blanche, et c’est d’ailleurs le nom du blog<\/a> dans lequel Cyprien Verseux raconte son s\u00e9jour : une base scientifique encore plus isol\u00e9e que la Station spatiale internationale<\/a> o\u00f9 les conditions de vie ressemblent beaucoup \u00e0 celles que rencontreraient des astronautes install\u00e9s sur une base lunaire ou martienne. Il y fait tr\u00e8s froid (jusqu’\u00e0 -80\u00b0) et la base est inaccessible 9 mois par an, obligeant ses occupants \u00e0 faire preuve de grandes capacit\u00e9s d’adaptation. Un endroit o\u00f9 la survie de tous ne d\u00e9pend que de la technologie et de la force mentale de chacun, comme ce sera le cas au cours des futurs longs voyages loin de notre plan\u00e8te Terre…<\/p>\n","protected":false},"excerpt":{"rendered":"
