De nombreux chercheurs pensent que la plan\u00e8te Mars pourrait abriter de petites formes de vie microbiennes. Pour voir de telles cr\u00e9atures, il vous faudrait un microscope. Les identifier serait l\u2019une des d\u00e9couvertes les plus importantes jamais faites. C'est l'objectif de la mission ExoMars de l'ESA !<\/p>\n<\/div>\n<p>La premi\u00e8re partie de la mission ExoMars sera lanc\u00e9e en mars 2016. Un v\u00e9hicule spatial baptis\u00e9 TGO (Trace Gas Orbiter) orbitera autour de Mars \u00e0 la recherche de substances chimiques qui pourraient avoir \u00e9t\u00e9 \u00e9mises par des formes de vie. Les donn\u00e9es collect\u00e9es par TGO nous donnerons des indices sur les lieux o\u00f9 nous pourrions trouver de la vie sur Mars.<\/p>\n<p>Pendant ce temps-l\u00e0, une petite sonde nomm\u00e9e Schiaparelli tentera de se poser sur la surface martienne. Schiaparelli est \u00e9quip\u00e9e d\u2019un \u00e9quipement de pointe et de nombreux capteurs qui permettront aux scientifiques de la mission d\u2019\u00e9tudier avec attention chaque phase de l\u2019atterrissage. Les ing\u00e9nieurs de l\u2019ESA pourront ainsi parfaire la nouvelle g\u00e9n\u00e9ration d\u2019atterrisseurs martiens !<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"625\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/03\/ExoMars_rover\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2016\/03\/exomars_rover\/17875370-2-eng-GB\/ExoMars_rover.jpg\" alt=\"\"><\/figure>\n<p>La deuxi\u00e8me phase de la mission ExoMars sera lanc\u00e9e en 2018. Un robot de pointe, baptis\u00e9 \u00ab ExoMars Rover \u00bb, mettra \u00e0 profit les enseignements tir\u00e9s de la sonde Schiaparelli pour se poser en toute s\u00e9curit\u00e9 \u00e0 la surface. L'ExoMars Rover partira ensuite \u00e0 la recherche de zones susceptibles d'abriter des organismes extraterrestres.<\/p>\n<p>L'une des particularit\u00e9s remarquables du rover ExoMars r\u00e9side dans sa capacit\u00e9 \u00e0 forer jusqu'\u00e0 deux m\u00e8tres sous la surface dans le cadre de ses recherches. Cette profondeur est suffisante pour que toute forme de vie soit prot\u00e9g\u00e9e des rayonnements mortels qui frappent la surface de la plan\u00e8te. Aucune autre mission n'a jamais \u00e9t\u00e9 capable d'un tel exploit ! Le rover ExoMars transmettra ses donn\u00e9es au Trace Gas Orbiter, qui les relayera ensuite aux scientifiques impatients sur Terre.<\/p>\n<p>Beaucoup de gens attendent avec impatience la mission ExoMars, car elle nous offre la meilleure chance \u00e0 ce jour de d\u00e9couvrir des traces de vie sur Mars\u2026 si tant est qu\u2019il y en ait.
