Les chercheurs europ\u00e9ens souhaitent envoyer un rover \u00e0 la recherche de signes de vie sur Mars. C'est l\u00e0 le message qui est ressorti du congr\u00e8s de deux jours de l'ESA qui s'est tenu \u00e0 Birmingham en Angleterre.<\/p>\n<\/div>\n

Mars est la plan\u00e8te qui ressemble le plus \u00e0 la Terre, et c'est l'endroit \u2013 hormis la Terre \u2013 o\u00f9 l'existence d'une vie primitive est la plus probable. Les donn\u00e9es transmises par la sonde Mars Express de l'ESA sugg\u00e8rent que la Plan\u00e8te Rouge \u00e9tait autrefois beaucoup plus chaude et humide qu'aujourd'hui.<\/p>\n

Sa surface gel\u00e9e cache-t-elle de l'eau ? Si tel est le cas, une forme de vie simple y survit-elle ? C'est pour percer ces myst\u00e8res que les chercheurs souhaitent explorer la surface de Mars \u00e0 l'aide d'un rover tr\u00e8s sophistiqu\u00e9.<\/p>\n

La mission envisag\u00e9e pourrait d\u00e9coller en juin 2011. Apr\u00e8s deux ans de voyage, l'atterrissage du rover sur Mars sera amorti avec des airbags et, si possible, des r\u00e9trofus\u00e9es.<\/p>\n

L'une de ses principales missions consisterait \u00e0 rechercher des traces de vie, pass\u00e9es ou pr\u00e9sentes. La charge utile du rover comprendrait notamment un dispositif d'analyse des gaz destin\u00e9 \u00e0 d\u00e9tecter des indices chimiques de vie dans l'atmosph\u00e8re.<\/p>\n

Un outil de forage permettrait aussi au rover de pr\u00e9lever des \u00e9chantillons de roche et de sol \u00e0 une profondeur de 2 m\u00e8tres. Ces \u00e9chantillons seraient ensuite analys\u00e9s \u00e0 l'aide du syst\u00e8me d'analyse des gaz.<\/p>\n

Toujours sur le rover, d'autres instruments permettraient de rechercher de l'eau, d'\u00e9tudier les couches rocheuses souterraines et de mesurer les secousses martiennes. Ils identifieraient aussi les dangers susceptibles de g\u00eaner de futures missions humaines.<\/p>\n

Voyant plus loin encore, les chercheurs ont aussi confirm\u00e9 leur volont\u00e9 de participer \u00e0 une mission de retour d\u2019\u00e9chantillons internationale en 2016.<\/p>","protected":false},"excerpt":{"rendered":"
